I imagine what was once a restaurant will become more like a dorm cafeteria. You just come in and eat what you will of what they’re serving that day. No more wait service. Most of the automation of the place will be like a factory, with machines doing continuous tasks with little more intelligence than today’s toasters. There needs to be an AI presence somewhere, but it will likely be offsite, and using specialized drones for non-repetitive tasks like maintenance of the machinery and the control of the rats.You are merely trying to suggest a scenario which YOU think CURRENT automated systems could not deal with. I will leave such issues to the experts in the field. — universeness
This goes against the morals of a huge percentage of voters. I mean, contraception is considered a sin by many, and forced sterilizations are not going to be popular with the voters. It also renders the species completely dependent on the baby farms. It hits one’s Nazi eugenics buttons where only ‘better’ people can breed, and only qualified people can raise children, not necessarily their own. Yea, the voters will love that.Yes but bodily autonomy may not be an issue in the future if the whole process is done outside of the body, as I am sure most women would prefer that, to the bodily trauma they currently have to go through.
There are those that consider it murder to not bring to term a female egg, whether via in vitro fertilization or via test-tube procedures like you suggest.No abortion as such would be needed just a case of completing a process or stopping it. I imagine, a whole new set of arguments would ensue.
Sounds like a possibility, but it would be probably easier to just combine the DNA of both into a waiting egg from which the female DNA has been removed. Remember that the two women also want to do this and might need one of their gene sets placed into something like a sperm cell. Also remember that the state controls reproduction and might decide that you don’t get to raise your own kids, or raise kids at all, even if you do breed some, so whether the genes of the kids you raise are yours or not might not be something you get to have if we’re implementing this test-tube world.How about a future where a man can be injected with a compound which makes him produce the equivalent of a female egg. This could then be removed and fertilised with sperm, from his male partner.
Most theists would probably embrace all that. I was one once and wasn’t taught the sort of exclusion that you might get from the more conservative church authorities. There are churches based on love and inclusion instead of the opposite.:lol: I would love to see the theist's react to that one.
It isn’t the sort of question that ones comes out and asks, but my son sort of dated somebody from such a family, so I did at some point find myself in their home. The girl’s father certainly put out an air of not minding what I (or my son) thought of his social status.Those on the bottom of the social status scale don’t seem to mind their position there, or the social disdain that comes with it.

You know this for certain? How many have you personally asked?
I don’t think the humans will have complete free travel. Sure, it’s a big zoo, but there’s parts of any zoo from which the tennants are kept out. Yes, the zoo animals can say what they want. No it’s not a democratic system, but I don’t think voters would yield their responsibility completely away to the point of it being a zoo. Who knows. Maybe they would. A zoo is pretty posh compared to the wild, especially when the ‘wild’ is everywhere not in this artificial enclosure optimized for humans. Being outside that would probably require life support.Do the animals in a zoo have free travel? freedom of speech and protest? a democratic vote?
Yes, those are all zoo amnesties. But you don’t get to choose to be a zookeeper. An assistant one perhaps.Free education? A career path of their choice with an ability to change their chosen life path anytime they wish?
So the argument goes. How big you think it should be? Less than a 1-10 million people on Earth? That seems plenty for a breeding population, and is well within the limits of renewable resources without resorting to importing something as dangerous as energy from off-planet. It would need to be spread out over several interesting places. I can’t get enough of mountains, especially since I was raised in a place completely lacking in them.If they do, then I would love to live in such a world zoo.
Most of that answer was ‘find more regions’, which didn’t answer the question at all. Better education and whatnot is going on now, and has almost zero effect. No breeding like rabbits is currently considered immoral by many groups. The propaganda isn’t capable of change unless the morals change first.How is population of a given region controlled?

A nice sound bite, but mistaken.What is it good for? Absolutely nothing!

It’s not supposed to, but it’s also quite human nature that corruption is likely, at least until you offload that task to the automation just like everything else. Can the automation be corrupted? Is it bound by popular choices? We all want (voted for even) guns so we can kill each other. Should the automated non-corruptible authority deny that because it wouldn’t make anybody’s lives better? Because I assure you, the only reason the USA has guns is due to sanctioned legal corruption.or can influence the actions of those in authority
It was, but not as much ‘cost’ as moving close to my employer.

OK, I think I get what you’re saying, but what do you do then with the person who wants to live in a place that happens to be quite distant from his place of work?

Is this person’s needs to be denied?I have no idea why you interpreted this as You don’t think long commutes are a waste of resources?
Sure, but slowly, not at a specific event like the pushing of a button that let ‘Skynet’ loose. The singularity isn’t like that. By the time we see it, it’s probably been there for quite a while.The development of an AGI/ASI, has been posited by many, as the technical singularity moment, that will ring the death knell for the whole human species.
Machines have long since done some things better than us. I think the definition needs refinement from this one. Any stupid search engine has faster access to a huge database of answers and can get to them faster. But so far it cannot create new knowledge, and I think that part is critical.From that site, we have:
What is artificial superintelligence (ASI)?
Artificial superintelligence (ASI) entails having a software-based system with intellectual powers beyond those of humans across a comprehensive range of categories and fields of endeavor. — universeness
I pretty much disagree with every statement here.A book contains data, not knowledge. Knowledge is created after you assimilate this data. (Check the term "knowledge".) And it is your mind that process this data, not your brain. The brain can only process stimuli. And stimuli are not data. — Alkis Piskas
OK, so you seem to be taking the language point of view, a refusal to use a given word to describe an identical process being done by something not on your list of approved categories. This smacks only of religious ignorance. Especially the bit about the suggestion of self-awareness (something that you assert only life can have) existing before abiogenesis (life), which seems to be directly contradicting your own definitions.AI can never become self-aware or even just aware. Awareness is an attribute of life (living organisms).
Didn’t get this. You want to harness the energy of a black hole? Kind of hard to do that from something from which no energy can escape.As for "Dyson spheres", I don't think so.

I did the tape and card bit, but am unaware of binary being input that way. That was mostly done with manual toggle switches. Very tedious, simple, and before my time. There were assemblers by the time I came around, and my punch-card input was typically some version of fortran.It could have been worse, you could have been a binary programmer in the days of punch cards or input tape
I don’t think binary code was every more than a few thousands of bytes. If you can’t bootstrap something more high-level in that amount of space, you’re in the wrong industry.Must have been fun trying to find a code error in a million lines of binary code
But that number (from Cantor’s proof) is generated from a countable list of rationals, not an uncountable list of reals. So it can be computed. It doesn’t require the ordering of the reals. That was my point,.Cantor's proof (by contradiction) shows that the set of real numbers is uncountable and thus can't be enumerated. Since the set of real numbers can't be enumerated, the diagonalized number therefore can't be computed. — Andrew M
I am not really clear on what a formal statement of metaphysical Copenhagen interpretation would say. I’m more familiar of its roots as an epistemological interpretation where collapse (of what is known) very much does occur, but it is just a change in what is known about a system, not a physical change. They’ve since created a not-particularly well defined metaphysical interpretation under the same name, and if it doesn’t suggest physical collapse, I’d accept that statement.Copenhagen-style interpretations also generally deny a physical collapse. So, in that sense, Copenhagen and Everett/MWI agree (and disagree with physical collapse theories such as GRW).
The empirical difference is between physical collapse theories such as GRW, and non-physical collapse interpretations (such as MWI and Copenhagen). From Wikipedia:
Cool. Interesting to watch then. Thanks.Such deviations can potentially be detected in dedicated experiments, and efforts are increasing worldwide towards testing them. — wiki
Totally agree with this, but it renders meaningless a statement about a single body in the absence of something relative to which motion can be defined.One body relative to the other body, is what is being discussed. Obviously, each is moving and neither is immobile. — Metaphysician Undercover
If there are two bodies with relative motion, then per the definition of motion, both are moving relative to the other, and the differentiation can easily be made by measurement. If there is but the one body, then motion isn’t defined at all.The principle of relativity states that there is no physical way to differentiate between a body moving at a constant speed and an immobile body.
I don’t. I said in my prior post that I could accept it, despite the non-relative wording of it.Why do you incessantly resist and deny the point of the principle of relativity?
If what is being discussed is one body relative to the other body, your choice of wording leaves the second entity unspecified, merely implied, like there’s some embarrassment about it. So say it. Relative to what is nothing immobile?The basic principle is that nothing is immobile (nothing is at rest).
And here I thought it was the definition of motion that did that. The principle of relativity seems to still hold even if you discard the relative definition of motion, and Einstein’s theories along with it.The principle of relativity renders the concept of "at rest" as obsolete.
If the PoR makes the concept of ‘at rest’ invalid, why does it (or at least the version of PoR that you prefer) reference it?… because by the principle of relativity "at rest" is not a valid concept.
Anyway, I will accept this as well. You don’t seem to be pushing the alternate definitions. In Minkowskian spacetime, a rest frame can be any arbitrarily selected frame and the is the implied second object relative to which motion is defined. The selected frame is an inertial one if Newton’s laws of motion hold in it, but other frames (with different laws) are also allowed.Then through extension of Newton's first law, a rest frame, or inertial frame, can be derived from any body displaying uniform motion because "uniform motion" is the concept which has take the place of "at rest".
I don’t find it unintelligible, but I do find fascinating the complete inaccessibility of such numbers to us. The vast majority of real values are these inexpressible values. I gave a few examples of them, especially ones that don’t require units which themselves are only approximately defined.What do you think this means, to assume numbers which cannot be counted nor computed? To me it's a form of unintelligibility, to say that there are numbers which cannot be accessed by us, or used in any way. — Metaphysician Undercover
From what I see, all the efforts have been aimed at reduction of the acceleration of the train, not even reduction of its speed. It’s not a fault. I cannot think of a being that has this capability. Perhaps this is evidence against intelligent design, because that’s one of the primary items I would have included in a decent design.If the people on the tracks, made the train, and caused it to hurtle towards themselves, then they are the only ones who can stop it. The optimists are not as passively waiting and are not as meekly accepting of the fate your pessimism suggests, they can do nothing about. — universeness
OK, I can accept that. I also had a paper-pushing job of sorts, but quite a good one involving significant creativity and pay. Such jobs will also be available for automation one the capability is there. It isn’t yet.

Soon automated, hopefully, same for all such tedious jobs.
It wasn’t so much a job that wasn’t desired, but rather management that nobody wants to work under. I suppose they can make machines that don’t mind being berated for not being fast enough, or machines that don’t need to wear diapers just because the boss thinks 4 hours between restroom breaks is a minimum interval (Amazon does this among others).You keep churning out such examples, and I keep repeating that I am confident that any job humans don't want to do, can be eventually automated.
Ah, now you finally mention the possible utility of consequences, even if completely unspecified.If anyone refuses to do their share, then I would not remove access to any of their basic needs, but there would be social consequence's of their refusal, to do their fair share.
This is an interesting conflict because I’ve never seen either side of the argument make the slightest attempt to acknowledge the points made by the opposing side. There’s almost zero rationality to it. I’ve been to rallies (you decide which side) and trust me, rationality is nowhere to be seen.Pro-life and bodily autonomy arguments and issues like it, will no doubt persist for a long time yet.

It’s not big-brother if it’s just preventing crime, right?You might find my suggestion here unpalatable, and you might even think that violence would be threatened or enacted against Jimmy, or Jimmy himself would respond to such social haranguing with violence, even though it would be prosecuted, if it was perpetrated.
I don’t know, I sort of favor the way they do it with the guy in the hut, but how to differentiate the layabout from the guy who has this busy hobby writing unpopular books and is too busy to pitch into community-necessary work that somehow cannot be automated? Some have excuses. Not all are able-bodied. Some are retired and exempt, and part of the code is to extend their presence as long as possible.Perhaps you can suggest a better way to reason with Jimmy, if all verbal reasoning has failed to date.
Just so. Then there’s no obligatory tasks, pretty much exactly like life in a zoo.Perhaps the issue would never arise eventually, due to the level of automation achieved.
Don’t think it can unite us. Sure, it can join two smaller groups into a larger one, as it always has, but it cannot, nor has it ever in history, made us one. At best it will be a total imperialistic state with one small group in control of everyone else as occupied states. If they kill off all the occupied population (as they seem to be attempting with Ukraine), then without anyone over whom to have power, the state will collapse into smaller units in mutual conflict. Imagine the entire planet controlled by somebody like Putin, with nothing but Russians everywhere and nobody left who isn’t one. That won’t last. The rules will not be the same for everybody. I can’t prove this, but it seems human nature that this is inevitable. A group needs an enemy to maintain its identity as that group. There’s never been an ‘us’ that seems to encompass all of humanity.Either war will destroy us all or it will eventually unite us all, as it has since we came out of the wilds. — universeness
If that was the outcome, there’d be no point to the war. No, the loser loses something, usually significantly more than just say their leader having to bend the knee.

You said this, just not in those words. You said people could barter for more than the essential needs provided by the state on what I called the black market. That makes for wealthy people. If not, then such activity (barter) should be illegal and all goods (say the highly sought after paintings) should be handed out by lottery or something, in which case they’ll all be destroyed in short order because the average Joe has no means to care for priceless artwork. The artist will probably not bother to make many, knowing this fate awaits them.If what you say proves to be true in the future, and the 'wealthy' still exist as you describe them above.
Agree, but it wouldn’t be for me, mostly for the same reasons I don’t pay the stupid tax.Yeah, a lottery win can be a death sentence for many.
I didn’t mention any ‘trick’. I’ve earned my nest egg without every having an employee. I do own a company of sorts now, but it’s just me. It pays far less than the days when I was employed, but I find myself not wanting to get back into it.'Earned the same amount,' is controversial, to say the least. The money trick means you can earn great wealth, not by particularly working hard but by sycophantically leeching from the sweat and toil of workers.
Ah, we seem to have introduced a concept of clean money, different than the usual definition (laundered). You seem to define it in terms of moral means of acquisition. My brother (the one I spoke of above) made his living day-trading for several years. It wasn’t gambling and he did quite well, but I told him that it wasn’t productive since the activity served the interests of nobody, no customer or anything. He stopped doing it (afaik) and now rents other people’s houses. That is a productive activity and I approve more.If you earned your millions/billions via investments and deals on the stock markets (gambling joints), then your wealth is via the money trick and is NOT CLEAN imo.
It’s efficient, and should be emulated by your perfect society. You just don’t like the money going to the owners. The brutal working conditions should be illegal though, but they’re necessary to be competitive. Your social society would eliminate that competition and theoretically make the working conditions far better, especially since nobody is going to be forced to do it by the necessity of needing to feed their families.That beginning, that resulted in the Amazon company that exists today and the abomination that is now the wealth of Bezos, is nefarious, and vile, and needs to be stopped from ever, ever happening, in the future.
You don’t think long commutes are a waste of resources? My last job was about 200 km away. I considered moving but the cost of living was so much higher there. So I went in once or twice a week and did a 40 hour shift and did the rest of the work from home. I burned 4 cars into the ground doing that. Every one of them was lost somewhere on the commute to that place.Sounds good to me! Apart from the 'waste of resources.' — universeness
Yes, but one car passing another isn’t a significant change. It’s a subtle one, even if the long term implications are not subtle. Maybe the cars are not side by side but km apart and nobody notices the difference.For me, the term 'information singularity' or 'technological singularity,' is more about a 'moment of very significant change.' — universeness
You seem to be deliberately avoiding the analogy, which is everybody on a train trestle (or tunnel) with nowhere to stand with a train present. The people cannot get out of the way, but they can slow/stop the train, but not trivially. But most (the optimists at least) assume the train will stop by itself or somebody else will do it. The pessimists know nobody else will do it, but even they don’t really have any good suggestions for preventing the train from arriving. There’s nothing nefarious going on (except perhaps those profiting from speeding up the train). The train is of the making of the very people on the tracks.People love to see trains coming. They bring stuff and take stuff and offer travel. — universeness

Not thinking of those being an amazing anything. How about just the person running a paper-pushing position at say a local doctor’s office. Yes, you can get the boost from doing something needing doing, being amazing about it in the eyes of others is a stretch. Respectable, sure. What about all those service jobs with a boss that makes every day misery? I know several businesses locally that permanently have help-wanted signs outside because they scare away employees faster than they attract them. Imagine that situation without the incentive of getting anything (event he ego boost) for your efforts.The rewards involved in helping others, can be as much of an ego boost, as someone telling you what what an amazing artist, singer, writer, scientist, capitalist, warrior, devil, angel, worshiper, athlete or tiddlywinker you are. — universeness

I’m speaking of those in a first world country that actively decide not to contribute. There’s a significant number of them. In the country with the hut, somebody making a choice like that would just starve. You’re describing a global first world situtation, so your comparisons shouldn’t reach for the opposite end of that spectrum.Most folks are forced to, yes, or do you think a 16 year old black boy living in a hut in a poor village in a 3rd world country or a slum ghetto somewhere, has the same opportunities in life, as your kids have had?
Of course I do. Not many of those voting otherwise tend to find their way onto a forum like this one. OK, more here than you’d find on say a science forum.Good, I am glad you vote, I hope you vote for those who are closest to secular humanism,
Prints sure, but it’s the originals which command the value. Those ‘sell’ by barter if nothing else, and command a significant exchange on the black market (any market operating outside the ‘to each according to their needs’ mechanism).If people like what she produces in HER CHOSEN JOB of 'artist,' then prints of her work can be downloaded by anyone for free, framed and put up on their wall.
Yea, that’s been a problem. China for instance steals software, copying it freely, thus forcing restrictions on sales of tech to them. An Xbox for example could not be legally be exported to China due to this policy. I agree that such laws are kind of pointless on a global communist society, but right now there isn’t a global anything economy. It’s just different independent countries each with different rules. The lack of unified rules is a huge part of the problem. How do you propose to move from how it is now to a unified thing?I would get rid of all copyright and patent laws.
Trying to figure out if/where the sarcasm kicks in. Yes, many people love art. Those guys get the prints. But the wealthy can afford the rare stuff, the originals, and there will very much be the wealthy. The artist in question will be one of them. Lack of a concept of money just makes it harder to tax.To the state, artists WOULD BE very significant contributors. Of course she is contributing to the well being of others. People LOVE art. Why is her work in so much demand, if it does not contribute to peoples well-being???
Seriously? Because it commands a price. She can trade it for other luxuries that are not included in the package available to everybody.Why would she put her 'original' paintings on to a barter market?
So do I. Did I say otherwise? OK, a luxury life does not imply a happy person. One of the best way to ruin your happiness and relations with everybody you know is to win a major lottery. The stats on that are very consistent. But a lottery winner is very different from somebody who earned the same amount.I think the artist you describe would be happy living under the system I am proposing.
I suspect the future for the personal vehicle (let alone a flying one) is doomed. Transportation in any sufficiently dense population is best done by mass transit. I’ve been in the places where many people don’t own cars since everything can be reached via bus, subway, intercity trains, boats, etc. Most of the personal transportation might be limited to bicycles. It’s too rural where I live to do that, but that raises the problem where many want to live in a scenic place like the mountains, but do work more suited to an urban setting. That makes for a lot of resources wasted on commuting, even if it is a mass commute.Every one will get 'one' of what they need for free, a house, a flying auto drive car, a home/mobile com system, a fridge freezer, home seating...

It also has nothing to do with world-creating. Planet Earth will be the same planet afterwards.But the philosophical implications of a world-creating, Singularity preceding the existence of our physical world, are of interest to me.
I could not understand that bit at all. It doesn’t involve an explosion, but it does involve growth of capability possibly going more exponential than the somewhat more linear growth seen today. That growth might not be so exponential since we seem to already be pushing the limits of Moore’s law.the information singularity at point of explosion pushes sentience across a threshold whereupon a "quantum leap" upward into a new, higher gestalt of cognition gets underway. — ucarr
You’re speaking of a mathematical singularity here, where certain laws of physics become meaningless when denominators go to zero and such. The information singularity is nothing like that. It’s kind of like one vehicle passing another on the highway.

Funny, but I don’t see that as scary. I see that as a destiny fulfilled.

That’s probably the best analogy I saw in the posts. The I-S is like that, a sort of critical mass that results in something self-sustaining like an atomic pile (or a meltdown), but not so over-critical that it explodes like a bomb.The intriguing part, according to my speculation, concerns the parallel of matter reaching critical mass just prior to radioactivity with elementary particle formation and likewise information reaching critical mass just prior to gnostic "radioactivity" with elementary knowledge formation. — ucarr
I pondered over this for several days trying to understand the arguments. I still hold to what I said. The section you mention nicely shows that the x generated from the list of computable numbers is not itself a computable number, but I was speaking of the x generated from Cantor’s original proof of some real not being a rational number. That x is computable, but not rational, and thus cannot be used as evidence that there are some real numbers not computable.Interestingly, the real number generated by Cantor's diagonalization proof is a computable number, so I’m not sure if this counts as evidence that there are some real numbers not computable. Once again, not disagreeing with the conclusion, only with how it was reached.

Collapse seems to be a choice of classical description of a quantum state, in other words, an interpretation-dependent thing. In interpretations with ‘jumping’, yes, it happens all the time, everywhere. In interpretations without it (such as Everett’s relative state formulation, pre DeWitt’s MWI), it’s just a classical effect, not anything physical that happens.What is ‘jumping’ in that quote? “Do we not have jumping then all the time?”.
— noAxioms
He's referring to the collapse of the wave function (i.e., a discontinuous change in the otherwise continuous time evolution of the Schrodinger equation).
I have serious doubts about that. It is a suggestion that there is an empirical difference between the interpretations, and yet I see not explicit prediction from any pair of interpretations that differ.Presumably [the AI in the box] wouldn't. But an AI (unlike a human) could be run on a quantum computer as part of a carefully controlled experiment, thus testing physical collapse theories that differ from standard quantum theory.

This is blatantly wrong. For one, the appearance of the sun revolving around the Earth once a day is not explained by the Earth revolving around the sun once a day any more than we’re revolving around all those other objects (moon, stars, etc) once a day. Secondly, the sun revolving around the Earth (once a year) violates basic Newtonian physics (lacking a reaction for the action of the sun). Newton’s laws were not in place back then so Galileo wouldn’t have known that.Galileo formulated the principle of relativity in order to show that one cannot determine whether the earth revolves about the sun or the sun revolves about the earth. — tau
This statement is especially ambiguous. Which of them is moving/immobile relative to what exactly?

Not one of them would be electable. You need a pessimist for one thing. Nobody is going to take evasive action if they refuse to see the train coming.Are you sure NOBODY wants to ensure the well-being, thriving and progression of our species, towards becoming as benevolent a presence in the universe as is possible?
OK, they got rid of the aristocracy, just as the French did. It was better than before, but it was never communist except in name. Maybe briefly at first, but people needed to eat and keep warm.There are definite similarities, between my politics, and the intentions of the hero masses of Russia and China, that got rid of the vile monarchy, aristocracy, plutocracy that ruled those country's so badly.
Yea, I don’t know enough about how all that worked. My knowledge of the transition to that gangster state is pretty poor. Don’t know how it all kind of worked before then, or how the rest of the world dealt with such a state.'The Plan,' as formed in Russia to create a fair, money free, socioeconomic system in Russia, was a brilliant system, that worked very well for the Russian people, when it was first introduced. Russia's decline into the totalitarian gangster state, it is now, started when the truly evil Stalin took power.
Hence my interest in designing a better system, even if only on paper. But my expertise makes me a naive contributor at best. They tried to do it in the USA, but clearly mistakes were made.An utterly crucial lesson, we have all, yet to fully understand and learn how to successfully prevent from happening again.
Admittedly, people are readily willing to shell out tens of thousands of dollars to garner an imagined approval from complete strangers. I wonder how much I fool myself into thinking I’m not impressed by it.There are very serious social consequences. People will still want to know answers to questions such as 'so what do you do?'
They’re forced to? They’re able bodied and educatable. That path isn’t forced. Taught maybe.The difference between then and now, is that they will have truly CHOSEN to live their life like that, rather than be forced to, as the majority who are experiencing life like that today, are forced to.
I vote. I hadn’t any plans to go into politics and rise to the levels where such things are decided.Well noticed! don't you think you should work with those who are trying to remove such consequences of the capitalist money trick?
OK. Suppose somebody is a very talented and popular artist. She creates works that are far more in demand than there is supply. So it goes onto the barter market and she gets wealthy with whatever the medium of exchange is. In the mean time, to the state she’s a non-contributor since none of her work contributes to the well-being of the whole. At best her side ‘income’ at least pays for the better art supplies since the state isn’t going to find need there if her work is on the non-contributor status just like all the other authors, artists and hobbyists, the ones whose work is noticed by a handful of people at best.I have no problem with the 'black market' you describe in the quote above.
If someone wants, say, an old/vintage car collection, that they do up, and show to others and drive around, then, the 'barter' system you describe, sounds good to me.
Everyone can take their basic means of survival for granted. As long as that is available to EVERYONE with no conditions attached, and such rights CANNOT BE REMOVED by any new authority, then I think we can accomodate the majority of the wishes of those who prioritise 'independent expressions of personal freedom,' and also allow, 'entrepreneurial aspiration.'
Irrelevant. So does communication between the two of us, whether on this forum or in person. There’s probably at least half a dozon translations/format-conversions done between any such communication, and this is without a machine bothering to parse it to the point of understanding. The ‘make a photon’ instruction might be a single hole in a paper tape. That’s how say one note might be conveyed to a player piano.I think we are probably imagining the same thing. Obviously, your instruction above would be in an HLL or high level language that would require translation before execution. — universeness
OK, you are envisioning binary machine instructions. I wasn’t since such an instruction processing unit is optional just like it is with the piano which works just fine without one. Nothing wrong with doing it via machine instructions.The 'machine code' level is the language code we are discussing here , not your 'emit a positron' language (I doubt 'please' will be needed).
Ah, a sort of 3D printer for food. Is that so unimaginable?Employing a source of photons to produce a photon or positron is not my challenge. It's producing a tech that can create a Tbone stake by manipulating the proposed digital level fundamental of the universe.
As I said, that is impossible (energy conservation violation), and Star Trek never suggested such a capability, despite their complete willingness to discard physics when it suits their purpose.A Tbone steak, produced, from that which is traditionally described, as the vacuum of space.
I don’t think there is any such thing. It’s a nice image for some purposes is all.A wave of light is an electomagnetic analogue waveform of continuous peaks and troughs that traverses the vacuum of space at a fixed speed.
You can’t zoom into it. Light ‘packets’ unmeasured are undetectable. Light measured is no longer light. This isn’t true of something classical like a water wave, which may lose its wave nature if you zoom in, but there’s still something classical into which one can zoom.If you could zoom right into it, I would expect to find that it is made up of discrete packets of energy/field excitations which might be vibrating strings or undulations etc
The law is 'You SHALL NOT add your speed, to the speed of light!' — universeness
Not true. You just have to use relativistic addition just like adding velocities of anything under Einstein’s theory.
It seems that in other sites that you cite, the term ‘non-relativistic’ refers to pre-Einstein views like Newtonian physics. — noAxioms
Nice reference, but this is a pop video by Carl whose audience is the naive layman. This does not stand up to physics. He implies that light is some sort of exception, that if you are on a bicycle going 20 km/hr relative to the road and throw a rock forward at 20 km/hr relative to the bicycle, that the rock would be going at 40 km/hr relative to the road. Well it’s close to that due to the speed being so insanely low, but it assumes Newtonian relativity, as does pretty much the entire video, understandable due to the layman audience.[Carl Sagan clip on ‘Thou Shalt Not Add My Speed to the Speed of Light’ — universeness
Not to disagree, but an assertion like that requires a demonstration that they’re countable.The computable numbers are countable since they be put in a one-to-one correspondence with the natural numbers. — Andrew M
Interestingly, the real number generated by Cantor's diagonalization proof is a computable number, so I’m not sure if this counts as evidence that there are some real numbers not computable. Once again, not disagreeing with the conclusion, only with how it was reached.However the real numbers are not countable per Cantor's diagonalization proof. Thus there are some real numbers that are not computable.
OK, they managed to test something whose outcome (the CHSH inequality violation) was already predicted by quantum theory. It’s a new test, but not one that changed the theory or any of its interpretations in any way.That just sounds like Bell’s theorem (old news). What in 2019 was added to that?
— noAxioms
The addition is that the experiment tests a Bell inequality for a Wigner's friend scenario (which the paper terms a Bell-Wigner test).
Not sure where you get this idea. PoR is defined in a few placesYou are reversing logical priority here. The concept "frame of reference" is derived from the principle of relativity, not vise versa. — Metaphysician Undercover
And from the special relativity paper itself:In physics, the principle of relativity is the requirement that the equations describing the laws of physics have the same form in all admissible frames of reference. — wiki
Each one of these definitions of the principle of relativity references ‘frames of reference’ or ‘systems of coordinates’. I would go so far as to say that the PoR is derived from frames of reference, but it certainly is defined using the concept. Thus the reference frame precedes the principle, else the definitions above would all be meaningless.They suggest rather that, as has already been shown to the first order of small quantities, the same laws of electrodynamics and optics will be valid for all frames of reference for which the equations of mechanics hold good. We will raise this conjecture (the purport of which will hereafter be called the “Principle of Relativity”) to the status of a postulate
…
1. The laws by which the states of physical systems undergo change are not
affected, whether these changes of state be referred to the one or the other of
two systems of co-ordinates in uniform translatory motion — Einstein,1905
That’s like asserting that a mathematical point or a location in space must have a size. Your choice I suppose. It seems to just complicate what is otherwise a simple thing.So when I said "every moment of passing time", I implied that within any "moment" there is inherently some duration of time.
Clearly those who maintain the zoo, the automations that do the actual (unpleasant?) work, who provide all the Purina human chow to all the people that want not. It might not be there primarily for viewing. It would definitely have a limited population. It is bad zoo policy to let all the exhibits breed without bounds.A zoo suggests the existence of outside visitors who will come and be entertained by viewing your captive status. Who would they be, in your zoo imagery? — universeness
True. It all seems to depend on who’s in charge. What’s taking responsibility for the management and well-being of the occupants. If it’s the occupants, it’s not a zoo. But then there are tasks needing to be done that nobody wants to do, such as the actual management and assurance of well-being of the occupants. Who for instance is going to enforce controls? These people are not going to be revered. Reviled is more like it. OK, there are plenty who would actually want to do those things, but those are not the ones you want doing these tasks. They’re the power hungry ones, the ones that are first to be corruptible.Dependence on automated systems does not assign you zoo status
You’ve described a full communist society, one without money, where everbody gets fed and housed and medical care regardless of level of contribution. That spell zero responsibility since there are no consequences to not being responsible.I have no idea where you get any notion of 'zero responsibility,' from.
Not necessarily. Certainly not in a society without money. If there is trade (you don’t get this unless you give me that), there is an economy, something evading the ‘to each according to their needs’ system.Black markets are money based.
That’s very different than positing that a quark is composed of multiple strings. Yea, I suppose strings could be expressed as something described by digital information.A quark may be a vibrating string state, for example, in common with all field excitations. — universeness
Why not? The data can be “please emit a positron”, and that data causes the machine to emit one (newly created at that).A process is not yet available that can create a photon from the data stored in a datafile.
A wave of light(electromagnetic radiation) and the quanta of photons, for example.
A wave of light is made of photons, which are waves of light made of photons ........What’s a wave of light then. I’ve heard of a beam of light, but a not so much a wave of it like a wave of water molecules.
Probably nearly the same as the speed relative to the space station. There being an observer in it or not doesn’t change that.What is your speed relative to an observer in a space station?
Not true. You just have to use relativistic addition just like adding velocities of anything under Einstein’s theory.The law is 'You SHALL NOT add your speed, to the speed of light!'
True, and I mentioned this above, but that’s like trying to solve global warming by frying Earth with a giant magnifying glass like we did to the ants back in the day.No it's not, as we can create extraterrestial renewable energy, such as solar power generation stations, built in space. — universeness
That’s what we’re doing now. Augmenting. Admittedly, the fusion fuel isn’t likely to run out in the near term.Also renewables can be augmented, by perhaps, new future tech, such as cold fusion.
It has happened, else the ‘augmentation’ wouldn’t be necessary. I share you confidence that the usage will drop below that line again.Yes, might never happen, it's not a fact that it will, for many reasons such as the ones I have suggested above.
That is very true, but such lifts require a clear path, clear of all the orbital space junk that we’re currently adding at an exponential rate. They’re talking of putting one on the moon because its not as expensive there, and the moon hasn’t all that much junk in orbit about it yet.Future tech such as spacelifts, might be very efficient.
Precisely what a probe is for, yes.It's not a vital point, as long as the necessary info is returned to those who need it, on Earth or otherwise.
But from my point of view, it was a conclusion reached after years of analysis.That's just confused thinking imo. — universeness
Totally agree. Unfortunately, the public education in my home town was pretty awful. I mingled with them during driver’s ed of all places and got a good sample of what those schools produced.A good education, only if you can afford one, is a vile concept.
Mine actually did a pretty good job, teaching that science is compatible with religion. Only later when the church decided it was the enemy was I forced to choose. I never got that from my school.I am also against all religious schools.
Well there’s a reason almost all my dutch relatives do their best to stay away from those institutions. They’re quite known for it. I personally didn’t see any of it since I didn’t live there.In all honesty, it seems to me that your judgement of those who administered palliative care for your grandparent, may be very harsh, but I suppose, such judgements are within your prerogative. — universeness
I had asked what the recognition was. Your answer was ‘nothing special’. That sounds like poor motivation. No, I had not suggested leaving people to freeze and starve.You prefer a system based on 'you don't do anything, that I or even WE, subjectively, decide has not met OUR standards,' so you will be left to rot and starve or freeze to death? — universeness
If they’re automated, then we live in a zoo. If the tasks are shared, then there needs to be motivation to do your part. The middle suggestion evades the question. The guy who should best do it is busy writing a book nobody will read.Such jobs will be automated or done by those who don't find them unpleasant or will be done by everyone on a shared basis.
Van Gogh comes to mind. Can’t think of any literary examples, but I’m sure they’re there.Most of the most revered works available today were created by people who got very little or no recognition during their lifetime and died in poverty.
Agree to all, but that’s not metadata, nor ‘extra bits’ in network packets. Redundant data in the cases above is there so if you lose something (a disk, an entire site), the data is backed up elsewhere.I taught computing science for 30+ years. Data redundancy is wide ranging. Duplicated data in database systems, too many copies of data, out-of-date data. — universeness
Yes, as I pointed out. Parity and ECC bits and all...In data packets, error detection and correction data has always been called redundant data.
This is ECC they’re talking about. Yes, it’s part of the actual data, and there to prevent costly retransmission of the packet in the cases of minor noise on the line. The bits cost perhaps 10-20% of the payload. Parity bits cost less, but that’s just error detection, not correction. Parity is common on disks and sometimes RAM, but ECC is more common in network packets.From wiki:
In computer main memory, auxiliary storage and computer buses, data redundancy is the existence of data that is additional to the actual data and permits correction of errors in stored or transmitted data.
We again seem to be talking past each other. It sounds like an assertion of one thing out of which everything is composed, like you could break a quark apart into them. If you don’t mean that, I don’t get what you mean.Quarks would not be fundamental, if the smallest bit of the information which 'defines' a Quark or a photon, is THEE fundamental of the structure of the universe. — universeness
They do that now, albeit with difficulty. Far easier to create say a positron out of a not-positron. Happens naturally all the time.Perhaps one day we will have the tech to create a REAL up-quark instead of a simulated or emulated one, displayed on some output media.
Sounds like an energy conservation violation to me. Even the fictional food replicators needed raw material from which to make its stuff, which is why you’d donate your dishes, dirty laundry and sewage back into the system.No, not a simulation or emulation. I used the word REAL. So, to convince me that information is THEE universal fundamental, I would need to witness a REAL machine like the food replicators on Star Trek, producing REAL food, from information only, not naturally produced seeds or animal flesh/produce!
A wave of what? A quanta of what?Yeah, so you have got past the a wave is made of quanta
No. Gravity is treated as a force under Newtonian mechanics. I made no mention of frames in that statement. I don’t know what a relativistic frame is as distinct from a non-relativistic one. There are different kinds of frames, but they’re all just arbitrary abstract coordinate systems.So gravitational waves quantise to gravitons but gravity does not consist of gravitons, gravity is not a force under relativity. So, are you saying gravity IS a force in a non-relativistic frame
Always wondered about the Satanists. I mean, the bible says if you believe in God, you go to heaven. Well, the Satanists believe in God as their sworn enemy. I'm sure the church has an answer to that, but I never asked. It's a funny religion since with most of them it's a test of how good you behave (and of course how much bribes were spread around). Nope. Jesus died so your worship of Satan can be forgiven. Your belief is enough to get you up there. Bet that's going to piss them off when they end up in sort of a prisoner of war camp behind enemy lines. Apparently the death of Jesus didn't forgive the sin of lack of belief. Seems quite incomplete and not very loving of him.or even satanists or pagans, are all still theists imo. — universeness
Both qualify as a computable number. The diagonalization method used with an ordered list of all rational numbers nicely produces a number that isn’t rational, but is very much computable by the definition on the site you linked. All one has to do to get n bits of precision is to list the first rational numbers and take a bit from each, a very finite task.OK, maybe, but it’s a very different definition. Is there an example of something that isn’t [a computable number]?
— noAxioms
Yes, one can use diagonalization to produce a number that isn't in the set. Another example is the probability that a randomly constructed computer program will halt (Chaitin's constant). — Andrew M
The page seems to assume infinite memory and infinite machines states. The more memory you need to access, the more states you need, and a machine emulating something needs more memory/states than the thing being emulated. The page seems to assume for instance a generic language where say pointers are not of finite size. But I’ll accept the definitions used on the page and withdraw my statement.A universal Turing Machine can simulate itself by accepting, as input, a description of itself and running it. See Turing completeness.
I agree with that, but I wasn’t talking about predictions. I was talking about language describing things other than the results.The experiment matches the predictions of standard quantum mechanics, and thus also the predictions of MWI.
Another reason why I don’t like the suggestion of actual metaphysical branching of worlds. Everett never suggested it, but DeWitt added that, coining the term ‘MWI’ in the process. I prefer Rovelli’s take on it where there is no ‘actual’ about any of the measurements, and observation serves only an epistemological purpose.So it doesn't challenge MWI on those grounds. But also, on an MWI view, it's disputable whether a measurement actually took place since no decoherence (and thus no world branching) occurred.
That just sounds like Bell’s theorem (old news). What in 2019 was added to that?So, if one accepts the authors' definitions for an observer and measurement, then one of the assumptions of free choice, locality, and observer-independent facts must be false.
Sorry, but I don’t see what the AI adds that any simple device (like the circuit on the camera) doesn’t.Which is why Deutsch's proposal to use an AI on a quantum computer would be an important and compelling experiment.
If I have to drop something, that one seems far preferrable to the others. I don’t reject it since it cannot be disproved.You're rejecting the "observer-independent facts" assumption, which is fine.
This does not seem to reference that definition, but more of the dictionary definition of observer.As John Bell inquired, "Was the wave function waiting to jump for thousands of millions of years until a single-celled living creature appeared? Or did it have to wait a little longer for some highly qualified measurer—with a PhD?" — Andrew M
That sounds like an absolutist statement, which sort of violates PoR. PoR might be used to say that any body is in motion relative to certain frames. Without the frame reference, motion is undefined.Under the precept of the relativity principle any existing body is always in motion. — Metaphysician Undercover
I’ve called it an abstraction, specifically an abstract assignment of coordinates to events. That’s true of any frame, inertial or not. So yes, an ideal as you call it.Would you agree that the inertial frame is just an ideal, and it does not actually represent anything real in the real world of physical, material bodies?
I’d have said ‘every moment of time’. I don’t see what the word ‘passing’ adds to that. That almost every body is subjected to nonzero net forces at any moment means that nothing exhibits inertial motion, but plenty of them exhibit good approximations of it to where the mathematics is very useful indeed.there is no body in the universe which is not subjected to forces at every moment of passing time.
And yet the total available renewable energy is fixed. Do you see what I’m trying to illustrate? A line that is going up has to eventually cross a horizontal one.Have a look at: Growth in energy demand, eg:
For a long time, growth in the world and the U. S. energy consumption as a function of time, follow what is known as an exponential function. Now it looks like we have switched to linear growth — universeness
That claims exponential growth, not linear.Where Greek letter Δ(delta) is the change or increment of the variable and λ (lambda) is the growth rate. After some mathematical methods, it can be shown that the equation changes to the form:
N=N0eλt
The question had been about other star systems, not stuff in local orbit. But I cannot find it economical to even do it in orbit. The energy needed to supply food to Earth from orbit seems vastly larger than the gain from the food. Sure, electricity is cheap up there, but electricity doesn’t get stuff in and out of orbit. Better to just export the electricity, except for the nasty side effect of having a giant WMD in orbit at the disposal of a species known for individuals that tend to take advantage of such capabilities.We might grow excess food in space and transfer it to Earth
Given all the hydrogen we have here, this seems kind of low priority. Also, where are you going to mine it? Jupiter has plenty, but it takes an obscene amount of resources to pull anything out of that gravity well, and then a whole lot more to transport it to Earth. There’s actually not a lot of readily available hydrogen except perhaps through the mining of comets and stuff.we may tap fuel sources such as extraterrestial hydrogen etc.
I kind of have, yes. One that works, albeit currently beyond our capabilities. That should change soon. But it takes a stupid long time to do it, so one of the most important features would be reliability and repairability. Things will go wrong and it can’t be a fatal problem.Seems like you have already set your own preconditions for our imaginary trip, ship and crew!
Yes it can, just like the Mars rovers phone back about the samples. The only reason they’d like samples back home is because there is a limited lab there on Mars, but an interstellar probe wouldn’t have that problem if complex lab analysis is a requirement.Returns? Can’t it just phone home?
— noAxioms
I'm sure it will but it can't phone home any samples it collected.
I’m not talking about rendering a person a total vegetable. I mean the indoctrination of the masses with lies designed to alter the behavior of the population in favor of whatever goals the administer desires. This goes on every day. I’m only against the lies that benefit special interest groups instead of the whole. There are good lies and bad lies, even critical lies. I believe certain things that I rationally know for a fact are false. Sounds contradictory, but its how it works.I assume you are against the concept of 'brain wiping' anyone and if you are witnessing 'brain wiping,' everyday, then I hope you are speaking out against it, in the same way you would speak out against any mental or physical crime you were witnessing daily. — universeness
The schools here are actually pretty good, albeit a bit on the dangerous side. I suppose that what I disapprove of is what lies parents are allowed to choose their children to be taught in publicly funded schools. My childhood school was not publicly funded, and the schools like that around here collapsed about 6 years ago, but are still going strong where I grew up, which happens to be ground-zero for Trump’s chosen secretary of education whose family actually funded construction of my high-school. Good school too, regularly placing tops in academic ratings.That's why I suggested you sound a bit mad sometimes in your turn of phrase. I assume you are not a fan of the current school curriculum content where you live or/and you don't approve of how some parents choose to inform or educate their children.
I agree that ‘wiping’ is too strong. Washing I think is the more usual term. All propaganda is a form of brain washing, designed to instill the masses with something other than the truth. My mother still suffers from some of the propaganda to which she was exposed as a child growing up in a Nazi occupied country.I have also witnessed what I would consider a biased or imbalanced approach to informing the young but I think 'brain wiping' is too emotive and more in-line with dystopian visions such as Orwell's 1984.
Oh yes. ‘Do no harm’ is a joke when the ending torture is considered ‘harm’. But keeping bright and comfortable person sedated deprives them of years of quality life.Would you allow people to end their life, if continuation means daily suffering with no or very little chance of improvement?
Screw the sedation at least. If there was unacceptable suffering going on, then yes, she should be allowed the choice. I wasn’t aware of any, and she was actually quite fine about a month before when they reduced the sedation long enough for my mother’s visit. I wasn’t there at the time.What would you have done differently for your grandparent, when you consider her medical status at the time?
So those recognized get the same thing as those that don’t. That isn’t recognition. You did great! You get to live. You over there, you don’t do anything! You also get to live. Yay system.The basic means of survival will be free, that's the recognition.
Somebody has to do the unpleasant jobs. You make it sound like everybody pursues their hobbies and nothing actually gets done.Yes, you would still be a contributor, as long as you wanted to try.
We are there. Anyone can blog for instance. Lots (most) of it dies in obscurity, hardly considered a vocation from the viewpoint of the system.Anyone can publish (we are kind of there now, with some free publishing sites).
You have a very funny definition of ‘redundant’ then. I’ve never seen the term used that way, nor have I ever seen metadata referred to as redundant, and I’m in that biz.The fact it is required to successfully send and receive the data packet is irrelevant to the fact that such data is redundant, in the same way the stamp and envelope and paper that a hand written snail mail letter uses, is redundant. — universeness
Actually, it’s often only that content that contains redundancy, usually in the form of ECC bits and such, unnecessary if the packet arrives unaltered at its destination.It's only the textual/imagery content of a snail mail letter that is not redundant.
No disagreement here.I know, but a data packet is a more often than not, a message fragment. Many fragments make up the 'message' or the picture or the movie or audio clip. The internet is a packet switching network.
This makes it sound like quarks are not fundamental. There’s different kinds, but they’re not made of ‘parts’ like say a proton is.A quark could therefore be quantised into a series of lower level data fundamentals and be 'processed' into any of the 'quark' variants (up, down, strange, charm, top, bottom).
Ah, you seem to be talking about some kind of simulation. Most simulations don’t find the need to put every simulated bit on any kind of output media. Mostly they need to know how it behaves, say if a simulated chip performs according to specifications. If it works, great. If it fails, they probably want to dig down to what part didn’t do what was expected, something perhaps not saved on the first pass.So, yes, if YOU as the programmer instructed 'make up-quark,' using some high level or low level programming code, then a program would be executed, which used stored data to create an up-quark.
Perhaps one day we will have the tech to create a REAL up-quark instead of a simulated or emulated one, displayed on some output media.
That part is actually pretty clear. Even without a theory of quantum gravity, the alternative (a classical universe) has long since been falsified. It’s quantum, we just don’t have the unified theory yet.Anyway, I think it remans very difficult to prove that at a fundamental level, the universe is quantum — universeness
Just FYI then: Gravity is not a force under relativity, and relativity isn’t a quantum theory (yet). Gravity doesn’t travel. Gravitons are the delivery/messanger particle of gravitational waves (that which LIGO detects), and not of gravity (that which your bathroom scale arguably detects). Gravitational waves transmit changes to the gravitational field (the geometry of spacetime). Gravitational waves are energy, lost pretty much permanently every time masses rearrange themselves. For instance, Earth’s orbit about the sun radiates gravitational waves at the rate of about 200 watts, which, barring everything else, will eventually spin all the planets into the sun after some obscene amount of time. Earth’s orbital distance is currently changing for 4 different reasons, and that one has the least effect, but will also continue longer than the others.No graviton has ever been found yet, but perhaps gravity is not a force and therefore has no delivery/messenger particle.
OK, maybe, but it’s a very different definition. Is there an example of something that isn’t in this set? Maybe my prior example of the half life of carbon 14. I called it a representable number, and I suppose that if you can represent it, you can compute it as per your definition, and if you can’t compute it, you also cannot represent it, except I think I just did in my example.I can still express the length √2 with two characters, a very finite state. Humans deal only with such representable numbers, and they’re countable.— noAxioms
Yes, computable numbers. — Andrew M
I think I just represented it with such words, so I’ll answer my own question.Do we know that "the ratio of the half lives of two specific isotopes" isn't representable? — noAxioms
Does the statement above apply to non-classical physical systems? Can it simulate say a quantum computer to arbitrary precision? Another interesting note about the above statement is that a Turing machine cannot simulate itself, which is not a violation of the statement.That question seems relevant to the physical Church-Turing thesis (Church-Turing-Deutsch principle) which says that any bounded physical system can be simulated by a Turing machine to any desired precision. — Andrew M
OK, I said I’d get back on this one. I admittedly get lost in the complex examples, but I did at least want to comment on some of the assumptions the paper is making, assumptions which are very interpretation dependent. The topic here is about how MWI would handle it.A related test has been carried out at a microscopic level (using photons instead of AI's) where it was shown that physical collapse does not occur. — Andrew M
A.Smith, this is also relevant to your question. No, no experiment has demonstrated a living thing to have a special role.Does the observer have to be conscious or are there non-living "observers"? — Agent Smith
An observer is apparently a clerk, reacting to a measurement and putting into some non-volatile state. A digital camera for instance has a CCD (the measurement device) and an SD card (the persistent state) and a bit of circuitry (the observer) to move the data from the CCD to the SD card. This is nothing particularly special, but they give it a very special role in the paper:let us first clarify our notion of an observer. Formally, an observation is the act of extracting and storing information about an observed system. Accordingly, we define an observer as any physical system that can extract information from another system by means of some interaction, and store that information in a physical memory. — PPGBKBRF
It seems that they’ve given this clerical role some special metaphysical status, that of arbiter of what is fact or not, and also the only physical process which is probabilistic instead of deterministic. I’m not sure if they’re asserting these things and strawman arguments to knock down or they’re actually pushing this.The observer’s role as final arbiter of universal facts [1] was imperilled by the advent of 20th century science.

in quantum theory, all physical processes are continuous and deterministic, except for observations, which are proclaimed to be instantaneous and probabilistic. — PPGBKBRF
This is suddenly a relational wording of the situation due to the addition of ‘from the friend’s PoV’. Suddenly the ‘observation’ doesn’t make anything a universal fact at all, as evidenced by Wigner’s measurement:According to quantum theory, the friend randomly observes one of the two possible outcomes in every run of the experiment. The friend’s record, h or v, can be stored in one of two possible orthogonal states of some physical memory, labeled either |“photon is h”> or |“photon is v”>, and constitutes a “fact” from the friend’s point of view. — PPGBKBRF
Rightly so. There are no facts, just points of view. The friend is measured to be in superposition of having recorded one fact and of having recorded a different fact, pretty much demonstrating a lack of universal facts. Establishment of those universal facts were the only apparent role of these observers, so with that neatly shot down, the observer plays no role at all.Wigner can now perform an interference experiment in an entangled basis containing the states of Eq. (1) to verify that the photon and his friend’s record are indeed in a superposition—a “fact” from his point of view — PPGBKBRF
Thank you for the definitions. The article you referenced makes no mention of ‘uniform existence’, ‘unchanging presence’ so it helps to define these terms up front if you’re going to use them."Uniform existence" is having an unchanging presence, as in not being acted upon by forces; what is described by Newton's first law, which is commonly referred to as "the law of inertia". — Metaphysician Undercover
A good definition, and it comes from the top of the article, not section 1.7 to which you linked. That section deals with pre-20th-century handling of what is now called accelerated reference frames. It even includes an early form of the equivalence principle as worded by Newton.Check the Stanford article I previously referenced:
“an inertial frame is a reference-frame with a time-scale, relative to which the motion of a body not subject to forces is always rectilinear and uniform, accelerations are always proportional to and in the direction of applied forces, and applied forces are always met with equal and opposite reactions.”
Unclear what your question was. I think I can take apart an assertion of a discrete granularity to space and time, especially if there’s any kind of regular grid to it, not that I suggest it being continuous either. Both seem to assume counterfactuals, something that I find unlikely.So what's your point with respect to my question (and its context)? — 180 Proof
OK, but a continuous voltage probably isn’t actually continuous since it is based on discreet charges of elementary particles, admittedly over non-discreet interactions.Definition of "analogue": Relating to or using signals or information represented by a continuously variable physical quantity such as spatial position, voltage, etc. — Alkis Piskas
All those can be produced to arbitrary precision with value holding only discreet values, which is why I don’t think there’s a proof of it. None of this constitutes even evidence, let alone proof. As I said, I suspect the same, but to prove it would involve measurement to infinite precision.Sound and all other vibration frequencies, electricity and otherforms of energy, etc. show that.
Sorry, but signals by man are no more analogue or discreet than natural ones. A computer signal for instance is quite variable and gates must operate on spec through a range of expected input voltages.From what I know, only artificial --created by man-- frequencies can be discrete (digital).
And I don’t. Talking about something doesn’t make it so.Moreover, what we can perceive in nature and which we can talk about is analogue. I think this is enough for a proof.
This makes no sense. If you claim a proof on non-discreetness, then you also have your proof against said illusion. Anyway, neither of us lays claim of a discreet/digital waves and voltages, so not sure why you find the need to disprove it.What we have actually no proof of is that this is an illusion and that the structure of the physical universe is digital/discrete.
That is true of every form of energy. You burn coal, you get the same mass loss from the same generated power. Remember mass energy equivalence?From a Quora discussion:
as shown in peer-reviewed reviews over the last 10 years, to be the result of the conversion of deuterium to helium, and that conversion involves a “mass deficit,” i.e., the mass of the helium product is a little less than the mass of the deuterium that was converted to helium.
That is a definite amount of energy, by the laws of thermodynamics; expressed as 23.8 MeV/4He. I.e,. that much energy is released for every helium atom formed. That’s a lot of energy for a very little helium. — universeness
Did they take into consideration an exponential growth in demand? Yes, I agree that 100% can be (and will be) met. Something has to happen to that growth then. I said as much above.From physics.org: Can we get 100% of our energy from renewables:
They demonstrate that there are no roadblocks to a 100 percent renewable future.
If you grow by 1 person a day (or any linear rate) forever, eventually there’s so many people that the average number of new people per person approaches 1, the no-growth value. This is not true of exponential growth, which is not possible in the long run because you can only spread the people out to vacant places so fast.I don't understand your logic here. Exponential growth and linear growth are both growth, why does 'the number of descendants per capita, in the long run, result in NO growth? — universeness
OK, building materials then. I already said that.if we don't have to rip out it's resources to build stuff on the Earth or extraterrestially.

Said ship has neither the resources nor the time (millennia) to send probes out to prospective destinations.

I suppose, but I see it more of a failure to do the right thing rather than putting it to a popular vote in the first place.If those who you would have labelled as 'on the correct side' of the situation you describe above, were unable to convince a majority of the stakeholders involved, that they should have accepted the federal grant then the failure is with that inability to convince.

None taken. I was referring to my own expression of it. I am very much a cynic. I’ve been complimented on it even.No cynicism was intended on my part.
I was asking about the form that this recognition would take. You didn’t answer that, but instead listed some things that maybe should be recognized. The homemaker for sure. My wife held few jobs, but contributed no less to the effort than did I. The kids were never in day care.No, I mean a homemaker or a home carer that is a relative, or a person who spends a great deal of their time writing stories or music or painting pictures or educating themselves or contributing to online discussion forums, etc, etc, should be recognised as engaging in activities which are recognised as 'having a job.'
I would not want to be on the top sports team then, even if I had the capability. Not worth the incredible effort involved.No, national and international level competitive sport would continue but for reasons other than the wish to become rich. Remember the starting point. Everyone gets the food, drink, shelter, education, legal and medical protection, the right to a job they want to do and the free training/education they need to do so, etc, erc, all FREE from cradle to grave.
That they are, which would make a simulation of our universe impossible with the sort of architecture we know, no matter how scaled up in size and power.Why? Spacetime positions are relative.
They’re usually called metadata. They’re not redundant since the packet would fail in its purpose without them. They’re sort of like the address on a letter, not part of the payload within, but still necessary. Parity might be redundant, but is there for correction of small errors during transmission. How is any of this relevant to the quarks? I guess that’s below.A data packet about to be transmitted will contain binary bits, that have no direct relevance to the 'payload' of the data packet. Such bits are normally called 'redundant data.
A packet is a message between two entities using a protocol agreed upon by both. Why would these two entities wish to communicate something about a particle? What message are you envisioning? If I said ‘quark’ to you (the receiving entity), what would you do with that message? Just trying to grasp what you’re talking about.There has to be a means of distinguishing between data packets who's payload is textual or is a bit map or is audio data etc. So, in the case of fundamental field excitations, there would have to be an ID system established to differentiate between a payload that was a coded quark, photon, electron, gluon etc.
I think you’re referencing a different sort of efficiency. Not even sure what you mean by that statement. Yes, fusion would be nice, and would likely solve the carbon issue since while still utilizing a limited resource instead of renewables, there’s an awful lot of the fuel available, at least for a while.A future cold fusion system will perhaps be the most 'efficient,' if we ever achieve it. — universeness
OK, this seems totally illogical. ER is limited by definition. You can’t make more, you can only attempt to waste less. OK, there are exceptions such as putting up solar collectors in high orbit, which is essentially a space-based death ray with a minor computer hack.ER (renewable energy) can rise to meet E if humans make it so.
This is a money issue, which you’ve dismissed. I’m not talking about money, I’m saying that ER has a cap.The fact that renewable energy is charged, in the world markets, at the same price per unit as 'the most expensively produced' energy is another example of the affect of the nefarious profit mongers.
Does it? Last I looked it still costs more. OK, hydro has always been pretty cheap, but not so much solar and wind. They’re based on expensive equipment which needs regular replacement. Part of this is subsidies, which need to be accounted for when comparing actual costs.Renewable costs much less to produce than fossil fuel based oil and gas
OK, you seem to be solving the goal of wanting excess population but first solving the problem of finding a place to put them. That’s different than having a problem of excess population and presumably trying to ‘save’ as many as possible.The justification seems obvious , in that, there is a lot more room in space than there is here on earth. — universeness
Agree, but how many of those declining population countries have negative trade deficits?Perhaps 'Countries with declining populations,' are an small indicator of the future of population control.
Exponential growth will always overpopulate a species no matter how fast they colonize new systems. That’s kind of simple geometry. I had done a topic on what it would be like with a planet of infinite resources/land/area. Each location has limited resources, but there’s always the frontier. Answer: Not exponential population growth. Linear at best, which is in the long run the same number of descendants per capita as no growth.BUT, as we slooooooowly become an extraterrestial species, we will have less need to worry about population control and have more need to encourage reproduction.
Fair enough. I’m trying to figure out what can actually help us on Earth that is best imported from off-planet sources. Certainly building material for stuff being built in space, but how does that help the planet other than to relieve them of the efforts needed to bring that material up from the surface?Eventually this will mean extra resources can be brought TO Earth FROM space.
They did export stuff back too, and yes, building materials was probably top of the list. Still, the pioneers landed in an environment for which they were already evolved, and an alarming percentage of them still died within a year or two.It's no different than it was when compared to pioneering humans on the move. They had to bring their supplies with them until they could establish a supply chain wherever they ended up.
If you have excess population, many are going to die anyway, especially under the ‘share all the world’ socialism where the most resources go to those needing it most. Not to ding that strategy, but some kind of ‘cut your losses’ mechanism needs to be in place to prevent that sort of thing from happening.Less savage solutions are possible. You are just being a bit impatient and lazy minded. :grin:
I suspect your brother and sister-in-law would smack you on the head for typing the above quote.

With pioneer missions to other worlds, scouting missions may not be an option. Coming back certainly isn’t, but a ship full of colonists would be heading to unknown conditions without the scout. By the time a robot gets there and reports back, its senders stand a fair chance of not being around to hear the answer. The trips take an obscene amount of time, all the movies notwithstanding that treat interstellar travel like a bicycle ride to the corner thrift store.The first missions are scouting and pathfinder missions.

Don’t personally know the mindset. They watch TV I think. I don’t very much, and it pisses a lot of acquaintances that I cannot join discussion of the latest twist in some reality show or something.Most layabouts get very bored quite often.
That would not be a layabout then, right?Perhaps they would want to use their mind and body in ways that they would enjoy and would help the society/community they live in.
All the cynicism above aside, I agree with this. Make the people and their children part of a whole, part of the culture. It works because I see it. Trick is to break the pattern of them identifying with the group encouraging the opposite. It perhaps means destroying cultural identity. It seems to work best in places with little of that, but then what do I know? I don’t live in those places.Communication, support, respect, cooperation, justice, etc etc must become foundational when it comes to how people are supported.
What does this recognition look like? Get a name on a poster or the nightly news? I mean, I do see it in some countries. In India, apparently your status is based on how many people you have under you. The recognition is an org-chart. You can be a brilliant contributor but don’t have any underlings, and you’d be pretty much a disappointment to your folks. I’ve seen this.A person who works to help their community (or even their universe) should be recognised
It would become like little-league then. I guess that works. No more sports section in the newspaper except perhaps a page about how the local teams did against each other.

It would take an infinite number of bits to describe a quark. Just its position in space (if there is such a meaningful thing, which there isn’t) would need infinite bits, even if done only as accurately as the nearest meter.Let's say I could represent an 'up quark,' by the binary rep:
10010000110110001101101110000110011100000011.
An identifier that say ‘up quark’ would suffice for 1, 2 and 4 since these are the same for all up quarks. The spin is a property of this quark, and per the vast majority of quantum interpretations, it doesn’t have one except when it is measured, and then only along one axis, so the actual spin can only be expressed relative to that one axis. A single bit will do then. Items 1-4 can probably be done in under 10 bits. The wavefunction of the quark would require, well, infinite bits.If I explain the above binary representation of an up quark as representing:
1. An unique identifier for an 'up quark.'
2. The charge on a up-quark. (relating to accepted units)
3. The spin or angular momentum.
4. Mass (accepted units)
Question seems to come down to where the purpose emerges from the matter. I’d probably favor a view that purpose is relative to a material process, not to matter, and not to an arrangement of matter.Matter has no purpose, i.e. intention or desire. This is an attribute of life, even if its purpose is reduced down an urge to survive.
— Alkis Piskas
Brain matter in humans contain and demonstrably manifest, human intent and purpose.
Well that can't be true since digital is just a subset of analog, so an analog system confining itself to those states can appear digital.A digital system can appear from a distance as analog, but analog never appears digital at any scale. — punos
Interesting assertion. It violates the principle of relativity for one thing since it would be a distinction if a thing is changing voxels or not. Such a statement is assertion of a preferred frame, the one in which these locations are fixed. How slow does something have to move to change one pixel every minute? How does it have any momentum/velocity at all if it stays in the same place for a minute, and then suddenly changes. That's a violation of momentum conservation at the fine level. How fast does it have to go to change locations more frequently than one unit of time?The nature of reality appears to me to be digital. Like 180 Proof mentioned, The Planck volume is no different than a pixel (voxel) on a screen, and it's quanta determines if that pixel or voxel is on or off.
What does Planck say? I thought it was a limit of meaningful measurability, not a metaphysical digital ontology.So you dispute Planck's quanta? — 180 Proof
... where all numbers are representable with finite states. — noAxioms
We may still be able to have a precise geometrical representation. — Andrew M
I can still express the length √2 with two characters, a very finite state. Humans deal only with such representable numbers, and they’re countable. Actual numbers in nature (such as the ratio of the half lives of two specific isotopes) are not in this countable set. I have a hard time with a model of the universe that requires only the former sort of number, such as one would get in a simulation. Actual numbers are more analog, like ‘so big’ with your hands held apart.
Maybe it does, such as if our universe is digitally simulated. In this case, the amplitudes of the split beam would not be √2, but close.Nature doesn't encode a digital representation of that number
Going to get back to you on this one. Interesting read, but the introduction is already full of interpretation dependent assumptions, such as counterfactual statements. I will look at it from my relational perspective which doesn’t make those assumptions, but thus far I’ve not read enough to really comment on it.In a state-of-the-art 6-photon experiment, we realise this extended Wigner’s friend scenario, experimentally violating the associated Bell-type inequality by 5 standard deviations. If one holds fast to the assumptions of locality and free-choice, this result implies that quantum theory should be interpreted in an observer-dependent way.

There’s actually no empirical difference between those two cases. There is if there was a true superposition, but there isn’t in the cat case. It’s been demonstrated with macroscopic objects, but under conditions which would kill any cat (such as being in a vacuum and almost 0°K).I'm just surprised that the statement that describes the Schrödinger =n isn't that of ignorance (The cat may be dead or the cat may be alive, we don't know) but of knowledge (the cat is both dead and alive, we know). — Agent Smith
I guess so. I would have said it is an abstraction, an assignment of coordinates to events.An "inertial frame" is a theoretical derivative. — Metaphysician Undercover
This is nonsense. You have a reference to such a crazy definition from a consensus physics reference from the last century? What even is uniform existence? That a body must be the same everywhere? A carrot cannot taper? I presume you to be an absolutist and maybe get your definitions from the sites supporting such, but this is not the consensus definition as used by physicists.It is derived from any situation with a body assumed to have uniform existence.
perhaps suggesting that any inertial frame with something moving (or accelerating) in it isn’t a real one — noAxioms
Case in point.To speak of an inertial frame with something accelerating "in it" is just deception.
No, not at all. I can for example reference the inertial frame of Earth when referencing the twins scenario. No duration is specified or necessary when identifying that frame.Do you agree that the passage of time is an essential aspect of the concept "inertial frame", a duration of time is necessarily implied by "inertial frame"?
There were lots of basic topics covered, down to interpretations of time near the bottom, but I didn’t see quantum interpretations mentioned at all, which requires probably a whole separate course.I encourage any Q-physicist reading this post to consider enrolling in this course. :cool: — jgill
Not quite. All motion can be specifed relative to a frame, specifically an inertial frame. Light speed is specified relative to (and is fixed only relative to) any inertial frame, so it isn’t an exception.The principle of relativity makes all motions equally relative to each other. — Metaphysician Undercover
Never said that. You’re saying it, and it’s wrong since it would exempt it from the principle. Light has no special status in this regard.To stipulate that one movement, "c", is exempt from that principle
The principle of relativity is one of the postulates of special relativity. Being part of that theory doesn’t mean anything gets special status. The word ‘special’ means a special case of no gravity being involved. With gravity, there are no longer non-local inertial frames and fixed speed of light goes away.is to remove it from the application of that principle, "relativity", and give it special status, and we are left with "special relativity".
I realize you think that, and I’m trying to actually grok your opinion to the contrary. But as I say, mathematically it doesn’t work. Light obeys the same rules as everything else, just like PoR says it should.I think you are "seeing" it incorrectly then.
This statement also seems to contradict what you’re asserting. Anyway, post-Michelson–Morley at least, new rules were needed since Newton’s application of PoR wasn’t working. In particular, relative velocity addition needed modification.Prior to Einstein there appeared to be no way to make the motion of light compatible with the principle of relativity.
First of all, one-way SoL still cannot be measured by any means, hence the speed being fixed being an additional premise, not something derived or measured. Secondly, the assertion you make (that these two observers would have to measure different speeds) does not follow from PoR.It was a practical problem involving the difficulty in measuring the speed of light. If light was included within the application of the relativity principle, then the person on the embankment, and the person in the train car, would have to measure the light from the same source as having a different speed.
Again I agree that such an exception would constitute a fundamental flaw, but this seems to be exactly what you’re suggesting.The problem is that the whole idea that we can employ the relativity principle, and arbitrarily exempt something like light from it, for simplicity sake, is fundamentally flawed.
This has no meaning under relativity theory, or for that matter any of the alternatives.space and time from the theoretical framework of light
Not necessarily so. Velocity might be specified relative to a frame of reference, but it just might by chance be the same from one frame to the next. PoR does not demand otherwise.You are using "relative" ambiguously, and you need to be careful not to equivocate. In the relativity principle, the motion of bodies is "relative" in the sense that velocity varies according to the frame of reference.
It is exactly relative in that sense. For one thing, a given pulse of light might be heading north relative to one frame and east relative to another. But the magnitude of that velocity would be the same, yes, which is exactly what you’d compute if you performed a Lorentz transform from one frame to another You find this fixed speed to be a contradiction, but PoR does not forbid it. It just says the rules of physics are frame independent. You cannot locally detect your motion in an inertial frame. If you can show how that could be done, then I’d accept that some kind of exception was being made. It could be done under Newtonian physics, and M+M tried to measure just that: a detection of local motion as the understanding of the PoR suggested at the time.But the motion of light is constant, "an absolute" in relation to the motion of material bodies, not variable or relative in that sense.
When you say ‘relative to light’, it is you that is using the term incorrectly. ‘Light ‘does not specify a frame, and you know that (or at least I hope you at least know that much).Therefore it is not "relative" in the sense of the relativity principle. So when you say the motion of light is "relative to material bodies" you are using "relative" in a way other than it is used in relativity theory, because every body regardless of its relative motion (according to relativity principle) is essentially at rest "relative" to light.
OK, I choose a roller-coaster track in a circle, and the frame where that track is stationary. We pack it with cars with no space between them. Then we get them going around the track together, and due to length contraction, spaces form between the cars. Are you going to tell me that there is an observer somewhere that doesn’t measure these spaces between the cars? That’s what I mean by the effects (length contraction in this case) being real, not just coordinate effects.I'll try anyway. To put it simply, the observer chooses the frame, so "frame effects" are observer effects.
Not even then, but motion would admittedly be pretty meaningless in a universe where time itself is meaningless.By the principle of relativity no body can be truly at rest unless all bodies are at rest. — Metaphysician Undercover
Sounds like you’re now in denial of what an inertial frame is, perhaps suggesting that any inertial frame with something moving (or accelerating) in it isn’t a real oneSo "inertial frame" is a sort of arbitrary designation requiring only constancy, uniformity.
The principle does not define ‘rest’, and certainly does not suggest that there is but one rest frame, a direct violation of the principle.Motion which stays the same as time passes is the principle of relativity's "rest".
OK, this is pretty much rhetoric from the relativity denialist literature. You’re entitled to this opinion, but none of this is part of relativity theory.And as you say, the motion of light "c" is relative to any inertial frame. But "inertial frame" is a feature of the theory, it is a theoretical observational tool derived from the uniformity observed in the passage of time. What defines the "inertial frame" is the uniform, constant passage of time.
OK, so where should light be at the rate of one hour per hour (just guessing at the rate)? IOW, what the heck does that statement even mean? What if time passed at one second per day? How would that affect where goes or what we see?Therefore the speed of light is not grounded in, or relative to any material bodies, it is relative to the defining feature of the "inertial frame", which is the uniform passage of time.
Yes, so we either have two or more worlds in a box, or they’re not really worlds. Either way, it’s different than there being just one state and we just don’t know.I thought that superposition is a fact and not just a hole in our knowledge. — Agent Smith
Ouch. It would really such if nature allowed such approximations. I’d always envisioned pure mathematics behind the physics, not digital mathematics where all numbers are representable with finite states.Any irrational number can be approximated to an arbitrary degree of accuracy by a rational number. From the associated paper: — Andrew M
The discussion was about observer effect (the observer causing effects), not observed effects (effects merely noticed by the observer), Relativity effects seem to fall under the latter category, prompting my foul call.Yes, it is quite different. As is the effect you mention of a clock travelling fast towards you that appears to be ticking faster than it is. Perhaps we can call them (classical) perceptual effects, (relativistic) frame effects, and (quantum) measurement effects to disambiguate them for the purposes of this discussion.
Not sure what this is. Got a link for this one?A related test has been carried out at a microscopic level (using photons instead of AI's) where it was shown that physical collapse does not occur.

How much carbon would be released from the production of the energy needed to fill those spaces? It’s a sort of efficiency question.From Howstuffworks:

The point is, ER is fixed and E is exponential. The one mathematically cannot keep up with the other. ‘Efforts‘ don’t change that.I fully support all current efforts to make E=ER, based on your representation of E and ER.

Yes, exactly. It costs far more resources to put a person in space (especially to keep him there) than it does to keep the person on Earth. If you have population in excess of the capacity of the resources, then for every person you put in space, 1000 or more must go without resources. That’s why space isn’t a solution to excess population. You say ‘of course it is’, but then you argue for my point like it was a money thing and not a resource thing. I never said it was a money thing.It costs resources to put people in space, not money. — universeness
No, the planet is the river or sea, the natural habitat of the fish. The bowls in the trees are these sealed enclosures on other planets (the trees), a place for which the fish are not evolved.I have already answered this point. This planet is the equivalent of your fish bowl comparison.
OK. I see a difference. Each day is one accident away from being exposed to the actual environment instead of the artificial one. That accident doesn’t kill us here, but it would anywhere else. A windy day will empty the bowl of water in the tree, but the bird can take it. Better to put a bird there.I see no difference between that and living in a space station or domed city on the moon or Mars, that we cant survive outside of.
Go there yes, but Hillary didn’t live on Mt Everest nor did Armstrong take up residence on the moon.Which is also part of the why we must go beyond Earth, we will go to Mars and live there one day because it exists, and it beckons us.

Democracy needs to fix that, and I don’t know how it can and still call itself democracy.So, you accurately describe the failure of the current USA political system to prevent a horror like Trump getting elected — universeness
No? You can grow a human from a single cell. It can metabolize and reproduce.What a strange conflation! A biological human cell is not a lifeform.
Nonsense. There’s plenty of living things without a brain. All multicellular life forms evolved from what were once single-celled individuals that needed to solve the problem of selfless cooperation in order to take it to the next level.Humans are a combinatorial of many sub-systems yes but for me, the concept of 'life' applies to the brain.
In what way does this counter what I said (which I left up there)? I’m saying that majority rule isn’t going to result in the kinds of action/policy needed.The sort of authority I’m speaking of needs to act on the benefit of the collective, but here you are suggesting this cannot be done because it would involve actions not popular with the individuals.

No, democratic socialism supports majority rule.
I’m not talking about benefit to minorities, and it seems that the typical voter isn’t very informed these days, and is not supportive of said secular humanism, as evidenced by people like Trump getting the majority vote on a platform against it, and against informed facts. I’m talking about benefit to larger goals like the future of humanity (said collective above), which often don’t benefit the majority of the voting individuals.an informed majority that supports secular humanism
I didn’t know that was attached to the big-brother label, but yea, that’s pretty much what I see. Big brother is supposed to be nefarious, not something that has a goal of the betterment and continued existence of humanity. And there are larger goals than that as well, but I’m not sure if a human should champion those.That sounds like someone wearing a 'big brother' garb, deciding that a large majority of people are incapable of 'knowing what's best for it.'
Amen. Wouldn’t want it, not just because I lack the qualifications.You make yourself sound like a person who should never be given significant authority over others.
Not much. President of one country lacks the power to do things on a humanity scale. Also, the laws pretty much prevent some decent suggestions I’d have for America, first of which would be the abolishing of over-the-table bribes. Money-talks is a horrible system that yes, just makes rich people richer.What would you do as president of America.
Nope. Doesn’t work on portion of the whole.Surely you would not use your 'mommy' model to drive your policies that would affect all Americans.
How can a socialist system do that? The layabout seems to get the same personal needs met as the inovator.Democratic socialism MUST encompass personal freedom and the entrepreneurial spirit as much as it can.
It takes that kind of resources to do certain things. How do you build a modern chip fab without those huge expenditures of resources, especially when money doesn’t even exist anymore to track return on expenditure of said resources?No billionaires or multi-millionaires are acceptable via business dealings or entrepreneurial effort.
Agree, but how to combat that? City (or country) X has a sports team with a lot of fans behind it. How are they to attract the better talent with promise of only modest means for their work? How are you going to prevent some other city from promising better means to this athlete, especially when this tiny extra expenditure would mean the difference between the city’s team winning or not?No celebrity roads to ridiculous riches.
Don’t think it was ever an attempt at something that would. It seems to be a step up from a simple google search that is far better at parsing native language, thus being able to find relevant results that a regular google search cannot.

They are very different things, and I meant ‘bigger’. Still one universe, but more of it than the story you found comfortable as a child. There were other universe theories (the only reasonable alternative to the intelligent design argument) long before Everett came along, so having other worlds is hardly a painful step.Notice the quotes around 'bigger'. What I think you actually mean is, 'many'. They're very different things. — Wayfarer
He also held to locality, so I think he would have liked an interpretation that was both local and deterministic.Einstein didn't like the uncertainty principle or the 'quantum leap' because he was a determinist.
I suspect that decoherence calculations do just that.The observer problem is a problem because there’s nothing in the maths to indicate where the observer must come into the picture. — Wayfarer
That it does. I’ve discarded that principle, as do most of the interpretations. The science doesn’t care. Quantum theory is not concerned with what goes on in the absence of interaction between systems.This undermines the principle of objectivity
What if the ratio isn’t rational?Per your comment, "one also has to deal with how some of them are more probable than others", the basic idea (from Zurek - see the above post) is that paths that are not equally probable can be mathematically reduced to paths that are. For example, a beam splitter with a 2:1 transmission/reflection ratio is equivalent to a beam splitter with a 1:1:1 ratio once a 1:1 beam splitter is added to the transmission path. — Andrew M
There's an 'observer effect' in Einsteinian relativity which nobody objects to. That's not the problem. — Andrew M
There is? There are dependencies on frames (what velocity has object X?, a completely frame dependent question since Galileo), but I've not heard that observers have any effect at all. — noAxioms
That is a dependency on a choice of coordinate system. No actual observer need be present, or be stationary, in an arbitrary choice of coordinate system. The people on the platform and the train may (or may not) just happen to make different choices. You make different choices for yourself, such as using one frame to describe where your house is, and a completely different one to describe what Neptune is doing (which is moving faster than c in the frame you probably chose for your house).Yes, I'm referring to frame dependency. — Andrew M
That’s quite different than the interaction (measurement) actually changing the system being measured, which is what this topic is about.While the laws of physics are the same for all observers, they may describe things differently from their respective reference frames.
On the contrary, he brought light to be included in the principle of relativity, that it moving at c was such a law of physics that was unchanging, part of the principle of relativity. He freed light speed from being relative to a medium, or possible relative to that which emitted it, in both cases being different from one frame to the next. We each see the same things differently. I see it as bringing light into PoR, and you see it as being taken out.What Einstein does with "special relativity" is to give 'special' status to light, freeing it from the principles of relativity — Metaphysician Undercover
But it’s motion IS relative to material bodies, or rather relative to any inertial frame including the one in which the material body is stationary. The second premise says that directly.to allow that its motion is not relative to the motions of material bodies.
But those are all frame effects, not observer effect. For instance, a clock coming at you fast will tick slow in your inertial frame, but it will be observed to run fast. Observer effects and frame effects are not the same.This amplifies the 'observer effect' by greatly increasing the possibilities for subtle differences. Now there is a need for principles like time dilation, length contraction, relativistic mass, and things like that.
Shouldn’t the cat simply be dead or alive then? What’s the difference when the box hasn’t yet been opened, other than the epistemological one where the lab guy doesn’t know the state of the cat.

There is no one Christian doctrine. There’s the bible at best, and I don’t think it encourages environmental destruction, but I’m sure one would be able to find passages to support such a view.

Yea, if God is so perfect, why does Jesus do things so incredibly differently in the NT? Pretty solid evidence of it all being a product of human legend if the story changes with the fashions.God spends half it's time in the OT, smiting people (one poor guy for dropping a corner of his ark of covenant). He also commands she bears to kill kids for insulting one of his prophets, and he demands murder and ethnic cleansing, all through the OT. It's not our sort of thinking that's the problem, it's the babble in the bible that's the problem, when deluded folks accept such babble, as the written will and character of their creator.

Space was never a solution to excess population. It costs far more to put a person in space than it does to keep him here. Sure, sending colonies to other planets might put new growth out there, but they’re not going to remove any significant number (other than by taking away their resoruces) from Earth in doing so.We want to explore and develop space not exclusively to solve our problem of excess population
They’ll never be as comfortable as Earth. Where are all the exatons of material going to come from (and of course the energy required, far more than it took to decimate Earth) to make outdoors of an alien place less immediately fatal to us?Us, as we are now, us with transhuman augments as well or exclusively transhuman augments, at least until extraterrestial habitats, are made more comfortable and practicable for us, as we are now.
Say you done it. Important with the moon since the USA got their butts pretty brutally kicked in the space race before then. Big cold-war motivation. One can always put ‘tech research’ out there.

The ones before were for learning stuff.What problem was being solved when Hilary climbed mount Everest or when Armstrong first footed the Moon.
Well I don’t have enough education to counter what is basically assertions on both our parts, but it seems obvious that the goals of the individual voter correspond little to higher goals, as demonstrated by recent history. Notice I don’t identity those higher goals. There are several, a matter of choosing one to at least the partial exclusion of the others. ‘Don’t ossify’ seems to be one to which you relate. Your fantasy cities seem to do just that. I like the idea of pushing forward and bringing it to the next level, but there are costs to that, most of which won’t be supported by the typical democratic voter who’s primary concern is his immediate personal comfort.My detailed arguments of why I think so would have to be a different thread about democratic socialism, secular humanism and a resource based global economy.
But we’re talking about even more power here, enough apparently to render the checks ineffectual. He basically fired anybody related to investigations on his abuses. The authority should not have any authority over said checks, but they always do, especially when the abuses were embraced by an entire political part just because he wore the same color uniform. Police are the same way, almost impossible to prosecute for abuses because the police and even the courts stand behind their own most of the time.episodes like Trump, do not negate the need for such rigorous (hopefully even fool proof), checks and balances, on all those trusted with power.
Disagree for the same reason the position shouldn’t be one left to the voters. Popularity will doom us. Our cells learned to cooperate into a larger entity, working for the entity and not the individual life forms. One of the first things to change was to select out any personal will that isn’t beneficial to the collective. The sort of authority I’m speaking of needs to act on the benefit of the collective, but here you are suggesting this cannot be done because it would involve actions not popular with the individuals.You certainly can consider unpopular decisions as a reason to consider unseating any leader or group of leaders.

But I did it with integers, so I guess it's not 'ontically fractional'.An ontically fractional electric charge is my attempt to describe an energy field that can only be accurately mathematically modeled to experimental observation by assignment of a fraction, and not by an integer. — ucarr
I don't see elementary particles with charges with those ratios, so no.Given this convention, could someone, by convention alone, assign -1/2, -1/3, -1/4... as numbers assigned to the charges of various elementary particles?
Yes, they are. Both moon and Earth contribute to the gravitational field, and their influence is not bounded, just like a = GM/r² never falls to zero regardless of how distant (r) you get from it.Does it follow from this that what we call the gravitational field of the earth and the gravitational field of its moon are really one gravitational field?
Depends on your definition of being real. I certainly don't see any hypercubes in this universe, but it indeed would take 4 coordinates to define a point within one.Does this tell me the hypercube is not a real entity, just an imaginary object of science fiction?
Evaporation of a black hole doesn't contradict energy conservation. It all comes back as radiation.Susskind's debate with Hawking re: the conservation of energy of material objects consumed by a black hole and the claims black holes are animate and eventually evaporate add complexity to the facts about where things are ultimately within spacetime.
You still haven't defined what you mean by 'ontically fractional', so the question is unanswerable. The numbers assigned to the charges of various things are just conventions. They could just as easily have assigned charges of -7, +14 +21 and -21 to down and up quarks, protons and electrons respectively. There's nothing special about where they assigned '1'.Does this tell me that a charge can be considered fractional in a ratio with another charge but not ontically fractional in of itself? — ucarr
Fields are 'the value of something at various points in space (or spacetime)'. Since a field by definition covers all of space, it would not seem to have a boundary. The EM field for instance cannot just stop somewhere, beyond which there are no EM effects. I think you're talking about not the field, but a given quantum excitation of one, but then the word 'boundary' only has classical meaning and I cannot figure out how to apply it to a quantum entity.I've been assuming energy fields have some type of physically real boundary. Am I wrong about this?
Spacetime has a time dimension, not a 4th spatial one. Certain higher theories like string theory posit more spatial dimensions, but they're not macroscopic like the three we know.We humans have reason to believe our world includes a fourth spatial dimension
Doesn't have to be just like the 3 you know don't need to be orthogonal. Making them so just makes the mathematics far simpler. The time dimension is perpendicular to the spatial axes, but the specific direction it goes is an abstract choice. Once 3 dimensions are defined, the 4th no- longer has any choice if they're all to be orthogonal.I've heard a claim the fourth spatial dimension is perpendicular to the other three spatial dimensions.
Didn't understand any of that. Work from the back: what theories, how are they evolving, and in what way is that relevant to the rest of this?I can now explain that the root of my inquiry pertains to the whereness -- I hope you can tolerate the neo-logism -- of material objects and how the perception of whereness is being modified by evolving theories.
’Many’ is a strong word. There’s plenty that actually stress betterment in this life. Would ‘the’ Christian church actually agree that it is OK to trash the environment since it is disposable?

OK, the guy is dead, but it must be God’s will or it wouldn’t have happened, thus I’m guilty only of implementing God’s will.

Other than those reasons, what problem is being solved by it? Why exactly does it need to be ‘us’ doing the exploring instead of something more fit, designed for the task.We want to explore and develop space not exclusively to solve our problem of excess population or the extinction threat we have due to 'having all on us on one planet only.'
Absolutely won’t work. The elected guy will be one that does what the people want, not what they need as a whole. It cannot work that way. This authority must be able to make the tough decisions and will not be able to if he needs to get elected.I want authority that is democratically elected
Agree that such a mechanism is needed, but it’s another thing that seems unworkable. Look at the failed efforts to put checks on Trump’s abuse of power.Authority that is answerable to very strong checks and balances that will instantly kick in, and cause any individual, to be removed from power, quickly and assuredly, if you are guilty of abusing your power and of acting nefariously.
Probably, except for above checks, some sort of watchdog that doesn’t have a say in the decisions. Very hard to give somebody (or an entity) that sort of power than then still be able to keep it in check. Can’t consider unpopular decisions to be justification for unseating the leader. But the decisions need to be judged in the light of their higher purpose.Your imagery of motherhood models of authority are dictatorial one's.
Irrelevant. The authority I speak of simply needs there to be children a long time from now, not necessarily all of them. That’s a different priority, a different sort of love.A mother may love her children or she may not.

I don't know in what way you might consider a quark to be fractional (or worse, 'ontically fractional;) other than it being a part of something non-fundamental like a proton. I also don't know what you're trying to convey with the phrase "expanding into .. dimensions". You seem to be trying to apply classic properties to quantum entities, which doesn't make sense. A quark doesn't have meaningful size, but a pair of them might have a meaningful separation.fractional quarks and gluons are expanded into three spatial dimensions — ucarr
It is meaningful to talk about fractional charge, like a helium nucleus has 2/3 the charge of a lithium nucleus. Again, I don't know what you mean by boundaries of a field excitation. A field is arguably 4D, so the title of this topic might be about being trapped in a 4D world. I don't think an excitation has anything that can meaningfully be considered a boundary. An electron for instance might be measured anywhere with finite probability.Do the fractional charges of quarks play an essential role in the outer boundary of a quark's field excitations? — ucarr
On face value, the many-worlds interpretation of quantum physics seems the opposite of parsimomious. — Wayfarer
Wayfarer, I know you have a hard time with a 'bigger' universe, but many of us don't. These same sentiments were expressed when it was discovered that the stars were other suns, and then that there were other galaxies as far as you can see. People balked every time it got bigger, but they got over it.It depends on how parsimony is understood. Many Worlds has the biggest universe but also the fewest postulates. — Andrew M
Totally agree here, but I think the effect with which MWI has trouble explaining is the Born rule. It's been a strong piece of criticism.The problem that the interpretation should solve is to explain the interference phenomena that we observe. Not merely to predict observations - that's what the formalism does. If Many Worlds were shown to be untenable, Wallace and Deutsch would say that we have no viable explanation (that we know of). — Andrew M
There is? There are dependencies on frames (what velocity has object X?, a completely frame dependent question since Galileo), but I've not heard that observers have any effect at all. That seems to be confined to QM effects.There's an 'observer effect' in Einsteinian relativity which nobody objects to. That's not the problem. — Andrew M
That sounds cool. In my experience, new evidence just moves the goal posts. An interpretation like the consciousness one will just adjust its story if the linearity of QM can be demonstrated. Others may actually fall out of contention.Deutsch's experiment provides a way of distinguishing between linear interpretations such as RQM/ QBism/Many Worlds and non-linear interpretations such as consciousness-causes-collapse/objective collapse theories like GRW. So it would enable us to rule out an entire class of interpretations. — Andrew M
I am actually very unfamiliar with how they do such tests. I mean, the double slit thing is pretty obvious, but how do they test for superposition of spin? Far worse, they've succeeded in putting something large enough to see with the eye, in superposition of vibrating or not. My question is, how was that demonstrated? How might one actually attempt to do the sort of test your're talking about with the computer?In the Wigner's friend thought experiment, the friend's lab is a closed/isolated system. A quantum computer provides a way to realize that isolation for a large, complex and artificially-intelligent entity (the friend AI). Then we can test for interference. — Andrew M

An activist on the right side. She calls for action, but I cannot actually find any suggested action that doesn’t just fall under the category of slowing the advance.You have heard of folks like Greta Thunberg, yes? Why have you heard of her?
If you’re dead, you cannot be revived. So their hope is that the definition of ‘dead’ changes between getting frozen and getting thawed. That definition is always in flux, so it’s a solid bet. No, I don’t think it would be torture either way. You’d certainly not be a conscious popsicle for decades.I am probably sensing a 'misinterpretation' incorrectly here but just to be sure, you are not under the impression that they cryogenically freeze you just BEFORE you die, if you sign up for that service, do you? You have been declared medically brain dead before you are frozen so of course 'freezing isn't torture,' it would be, if you were still alive when someone was doing that to you.
That’s the life in a box. Wouldn’t it be a lot easier to do it here, kind of like Logan’s run? Environment goes to hell, but at least not Mars-hell.

Plenty true of most individuals I know. It’s the larger groups that can’t do it. The larger the entity, the less mature their relationship with other such entities.Many folks have done and still do, dedicate their lives to try to improve the lives of everyone else, surely you are willing to admit they exist and support them in everyway you are able to.
Yes, that one. Capitalism has a nice motivator for that, but I have to admit that socialism also can do it, as evidence by the work ethic of more social countries. I suspect much of the problem is identification of a non-cooperative attitude with your peer group. For example, resistance to the Covid vaccines has been assiciated with a conservative viewpoint. Getting a shot is seen as a vote for the wrong party, so they don’t. I lost a sister-in-law to that mentaility.

I didn't get where in the 2nd vid that Deutsch suggested some kind of empirical test that should yield different results from one interpretation to the next. I'm very skeptical of that. — noAxioms
This seems to suggest that it is quantum theory that would be falsified given, well, apparently some sort of confirmation of 'consciousness causes collapse', except that in itself is another quantum interpretation (the Wigner interpretation) which was abandoned by Wigner himself due to it leading to solipsism, not because it in any way refuted quantum theory.6:50 Deutsch: Yes, so if that happened that would refute the Everettian interpretation or, as I would say, it would refute quantum theory. — Are There Many Worlds? David Deutsch in conversation with Markus Arndt
OK. Do any of the interpretations predict a different outcome of this experiment than the others? It's pretty straight-forward. The friend comes out and only remembers classical stuff. The experience of being in superposition relative to the box exterior is in no way different than the same thing without the box. You can no more get interference of the friend than you can get the dead and live cat to interfere with each other. Perhaps this is not the case with the quantum AI, in which case is kind of isn't the Wigner friend thing exactly.Essentially, Deutsch's proposed experiment would implement the Wigner's Friend thought experiment. — Andrew M
OK. I remain skeptical of any claim that this kind of thing can be measured without interpretation-specific assumptions.By conducting an interference experiment on the joint friend/qubit subsystem, the Wigner AI would be able to determine whether physical collapse happened or not.
Interpretation dependent, but true in any local interpretation.But the point is, the object has no specific location until measured. — Wayfarer
The measurement became entangled with the emitting event? That sort of makes it sound like the measurement caused the emitting event. I have no problem with this given a relational view where ontology sort of works temporally backwards. A measurement causes the existence of something in the past (the moon say). Until it is meansured by you, it doesn't exist to you even if it exists relative to something else. Ontology as a relation.You can't say 'the photon caused the measurement' because this assumes that it has some definite existence in some unknown location prior to being measured.
That again seems the same as it existing, unmeasured. If so, not sure what changes upon the measurement.There is no 'something' hiding in an unknown location until measured
So Rovelli would say I think. Copenhagen might say that measurement makes us aware of it, depending if the interpretation is taken as epistemological or metaphysical. There are forms of both, and I don't know how the latter would frame this.- the measurement makes it 'something'.
Agree with the quotes. Do the words mean different things? The problems you point out is a good part of why I am skeptcal of realism.That is why, indeed, 'exists' and 'real' have to be put in scare quotes in this context.
No, that statement was not a criticism. Just noticing that they don’t really seem to be vocal about this subject. They do indeed not seem to address the long term issues, but nobody else does either, so religion is hardly taking a different stance here.Are you simply referring to the idea or criticism that many theists (especially christian/moslem fundamentals,) don't care about sustaining/protecting Earthly resources, as their focus is on their faith in their promised existence after death? — universeness

OK, we have different definitions. We feed the old and the poor. They used to starve before WWII.Nonsense sir! no current first world country is socialist.
OK, by socialist you want an economy devoid of currency. The problem there is the lack of the mommy. If some country does that, it cannot compete with the capitalist competitors in other countries. Balanced trade would falter, especially if there’s no currency to back that trade. A mommy would fix that since effectively the whole world would work the way you envision, but there’d still be little incentive to finding more efficient ways to produce things. This is a problem that needs solving. How do you salvage the advantages of the capitalism without the drawbacks? What do you do with the people reluctant to work? I mean, money is owed-labor in the end, and you’re throwing that away.They are all capitalist as they are all currency driven, free market economies.
Democratic? Most places are republics. What’s your definition of something being democratic?True democratic socialism has never been successfully established anywhere on the planet ..... yet.
If it’s self-sustaining without fossil fuel, then great! It’s a city. Where do the rednecks live?A resourced based global economy, would be the most significant human change to the way we live, since we switched from nomadic hunter-gatherers to fixed communities supported by trade and agriculture.

The 'church' needs to drop god — universeness
The local hospital by me was run by the church, hence prohibited some procedures that they decided made you immoral. Have to go somewhere further away if you wanted those options.Or, at least, every church/chapel/temple/cathedral/mosque etc should also function as secular homeless shelters, substance abuse support centers, medical support centers, etc, etc.
Using a solar panels to create light for crops is far less efficient than just putting the plants in the light. I’m all for solar panels over parking lots and buildings and such, but the solar farms are mostly covering land that could be used to grow something.Crops grown indoors depend on artificial light. Note that sunlight can be exploited for natural lighting or self-sufficient generation of electricity through photovoltaic solar panels.
That’s the rub. Every watt of renewable energy consumed (and it sounds like VF uses more than regular farming) is one less renewable watt that can be used elsewhere. The excess must be taken up by the fossil fuels. It’s why I’ve not bought into the solar farm thing. If I did, that’s just so much green electricity that somebody else can’t have. The net benefit of switching is zero unless your money actually buys more capacity such as panels on your own house.While renewable and alternative sources of energycan promote the ecological soundness of vertical farming, the practice can still have a considerable carbon footprint if it still depends on the use of fossil fuels. There is a need to improve first renewable and alternative energy technologies to guarantee environmental sustainability and energy efficiency of vertical farming."

It’s a good percentage of the random articles linked by sites like yahoo news or google news. Yes, there’s better written stuff out there, but almost impossible to find if you’re not explicitly searching for it. The algorithms for what gets put on the front pages of the site is not particularly based on factual content at all. This was a big change compared to only 20 years ago.Half the stuff I read has obviously never seen an editor and cites no credible sources.

But that's just half the stuff YOU have read, which is what percent of available 'stuff'?
Quite a bit. I just served 2 months on a grand jury and got a taste of the sort of evidence they collect automatically. They knew where these baddies were by phone tracking and car-license monitoring on the main roads. All the big tech companies (apple, google, microsoft, etc) are quite up front now that they collect data on everything you do on your devices. It gets pretty obvious when new ads appear obviously based on recent browsing history.How much merit do you give to 'big brother is watching you?'
That’s kind of evidence that it’s also not going to last long. Make your mark before you’re gone. Make something that can last. That’s as good a purpose as I can think of.I can only invoke the cosmic calendar again and say we have only been at this for a few seconds on the cosmic calendar scale. Give us a f****** chance mate!
We thought it got silly sometimes, but couldn’t exactly pinpoint where.It would have been fun to have been part of that discussion.

By symmetry, a negative IQ occurs about as often as one over 200. They’re out there. My youngest is at about 67 or so, low, but not newsworthy low. My other kids are over 100.I also didn't know IQ could be negative. — Agent Smith

Oh like the Russians are going to honor those contracts when things get tight. But yea, they’ll take your money.Several hundred people have already paid to have their bodies cryogenically preserved in three existing facilities in the US and Russia, and there are as many as 1,250 on waiting lists.
Didn’t talk about being an enemy of an idea. I said enemy of an environment. Better to make friends with it, work with it, not against it.I have already stated that I think that 'all of the above will be attempted.' I am hardly therefore 'an enemy' of any idea for how best to develop and explore space.
No, they’re both controlled pretty much by the same method. It’s not like airplanes flew over and sprayed for them.It's a lot easier to control frogs that to control human population
That’s what the robots say! Another typo? If we don’t do something about it, the frog method will get employed (no, not make grease spots on all the intersections).We can just dispose of a currently existing excess human population.
Doesn’t stop them. Nobody likes getting told what to do, especially if its for the benefit of somebody else. Also, there will be those who comply and those who defy and have a bunch of kids. Guess which group gets naturally selected out? We’d be breeding humanity for wanting larger families.Whilst we also try to educate people into understanding their current local circumstances and the folly of having children they and the government they live under are unable to, or are too corrupt to, or are to much under the influence of international interference to, support.
OK, I think they’re fairly exclusive imo. We’re not fit to do it, but what we can create can be fit to do it. Best odds of survival of humans is to not kill each other at home. It’s worked great for many species, but yea, not so much the dinosaurs.so it’s humanity’s survival that’s the goal, not the taking-over of the galaxy. — noAxioms
Both goals handshake imo,
Pretty much got that from you with your talk of humanity having a purpose of making some kind significant impact on the universe, like it served the purpose of the universe or something. Can’t make any more than a scratch if we don’t cause something to spread out, to outlast the death of our planet which is already about 80% of the way there.I don't approve of the aggressive sounding, 'taking over of the galaxy' imagery you invoke.
Civilization collapses. We still have metal, but it’s old stuff from before. Nobody knows anymore how to get more since it takes tech to get at it. We’ve mined all the easy stuff. It becomes a chicken/egg problem. Takes metal to get to get to the metal. Fear not. The salvaged metals will last centuries. The longer it lasts, the less we’ll remember how to get more when most of it has corroded away.’No metal? Please explain!
So is every first world government on the planet, just some more than others. Anyway, yea, I definitely get socialist vibes from you. The Scandinavian countries seem to do it best. Harder to be rich there.I am a socialist
It does serve a purpose, but isn’t implemented well anywhere. I mean over-the-table bribery as policy? That’s sanctioned corruption. Nobody blinks, and those getting the bribes are hardly motivated to vote that crap out of the law.who no longer sees value in party politics.
That’s the mommy I talked about. We’re not good at all about implementing something like that, but I agree, it’s absolutely needed.I currently support notions of global unity
Nice pipe dream, but no numbers. They say no servitude, but it’s all people shown doing the work, and they don’t show where the stuff comes from. No wind farms or other renewable energy apparent.Venus project:
We were being selected for it for a while, even if it’s on the decline now. If it becomes ethical to make modifications, we can reverse that trend, so I’m willing to suggest a future upswing.

and in anything ‘posthuman’.So, our knowledge increases as a collective. This is another example of what is emergent in humans.
They don’t though. Things just get tough from there on according to the story. You have a second chance of sorts, but the path is narrower than it was before the rapture. Tread it and you will be severely persecuted. So I was taught anyway. No, I was not raised by rapturists, but we covered this sort of stuff in school.Yeah but it's an 'end times' curio. Those who are not 'raptured,' perish!
No, but the church needs to get on the side of humanity instead of the side of the church. It isn’t ever going to happen.We don't need to kill popes.
These are all grown/harvested/distributed with fossil fuels today. They’re not a substitute for digging limited carbon out of the ground.How about genetically modified foods?
How about vertical farming?
Not talking about 2050. I’m talking about when there’s no more to dig out of the ground, coupled with what the environment will look like with that much greenhouse gasses added to what’s already there.It not like no-one is talking about it. For example, five-ways-we-can-feed-the-world-in-2050
Negative mass and tachyons are also valid under Einstein’s equations. Much of this wormhole stuff requires such exotic matter which theoretically is allowed, but isn’t open to actually existing. Really, a micro black hole? How are messages going to be sent fast utilizing a tiny bit of spacetime that is infinitely far into the coordinate future?

Only? That is that fantastic chance you were positing. We actually meed something where it is questionable which is more intelligent. Hardly disappointing. They’re probably as disappointed in us not being like them as we are of them not being like us.I think that we would be ecstatic initially, but eventually, we would probably be somewhat disappointed that we came so far to find only the equivalent of killer whales.
A colony where we’re not allowed to touch the environment? Sounds like a zoo for the Orka amusement.Yes, I hope we fully respect the alien killer whales and we leave their habitat and environment alone. Perhaps however, we may still be able to start a colony there.
I’m old enough to remember professional news reporting. It died when people stopped paying for it. No, those best of times are gone for now. Half the stuff I read has obviously never seen an editor and cites no credible sources.We probably currently live in 'the best of times,' at least so far, when it comes to being able to combat fake news.
I am in a way. My son has one of those smart speakers and it totally gives me the creeps to know everything in the room is being recorded in some google database somewhere. For a long time I was in the biz of selling places like google things on which to store all that data.That's almost technophobic sir!
I don’t see any collective purpose exhibited by the human race. There’s a list of nice-to-haves, but no actual striving for some collective purpose. Not even something as simple as ‘don’t go extinct’. But then, I don’t see any other species with a purpose like that either. We’re not worse than the sponges.I suggested such as a 'collectivised' or 'totality' of intent and purpose of the human race.
No electronics. It knows everything simply by always being right, by chance.Interesting, but how did this, I assume, 'electronic manifestation' demonstrate it's omniscience?

No doubt. A group of people split into life-expectancies of 70 and 200 won’t cause any trouble at all.The global population is made up of individuals! Anything that happens to an individual has the potential to affect everyone.
Nice summary, thanks. I have suggested that what is emergent in humans will not be human. To resist this is to waste our potential.The subject of this topic is what is 'emergent' in humans. I am interested in what is ultimately emergent in all humans, yes, or future humanity as it might manifest collectively or as a totality
I say that too, but I also say it’s a lot easier to fit the creature to the environment than the other way around. Be its friend instead of making yourself its enemy.I say, 'YES WE CAN and YES WE WILL!!!'
But not out-of-control reproduction. When I moved to this new place, there was a frog plague going on. Frogs everywhere. What good did it do them? Some months later they were all gone, populations back to (or even somewhat beneath) normal levels and it was easier to stop at the intersections again.I say that in the same way natural selection evidence suggests that reproduction, is a survival of a species imperative. — universeness
Ah, so it’s humanity’s survival that’s the goal, not the taking-over of the galaxy. That might be better served with the 95% population reduction and learning to get along with each other. If we can get through the collapse without extinction, it may actually sustain itself going forward. Hence my vision of the world in 1000 years in some prior post. Imagine a world with people but almost no metal.If there are more of us existing in many extraterrestial places, the we are less dependent on the Earths' continued existence for survival. Seems like common sense to me.
Got suggestions? I’m actually quite interested in ideas for a stable government system that doesn’t depend on the whole system of the poor being slaves to the rich. I don’t much know what I’m talking about here, so my views might be quite naive.when we have such vile economic systems as capitalism and vile political systems such as autocracy or plutocracy as our mainstream operating system for 'how humans are allowed to live.'
Studying doesn’t increase intelligence. But agree with the rest.It's not 'more intelligence' as it's either folks who don't demonstrate much intelligence, learning how to demonstrate more intelligence or it's intelligent people gaining a higher level of intelligence via more time to study!
First of all, the theists have a lot to do with encouraging overpopulation. The Catholics consider it a sin to not breed like bunnies. Their moral code forbids the very steps that would save humanity, perhaps as a way to eventually force God’s hand, like he’s got to step in before the crash. As for the rapture, I think most of its adherents would suggests a figure like 1-2% disappearing, not 94%.lol: Yeah, there are many autocrats/plutocrats/totalitarians/theists who believe in BS like the rapture, etc, etc who would support your trimming of the population down to 6%.
Not while the pope lives...I think it's more important to create equitable social/economic/political ways to live
Sorry, but no. If we’re not putting back what we dig out of the ground, then it is mathematically unsustainable. Playing nice with each other (sharing all the world – Lennon) is probably the worst strategy because everybody dies simultaneously, or you didn’t do it right.This planet COULD sustain 8 billion of us
How to do an interstellar colony: Build a smart ship that can do everything. Bring DNA with you. Take 100000 years to get somewhere, perhaps refueling if it doesn’t seem workable at close inspection. If it passes, introduce simple life, and then direct it just like at the teleological theorist posit. In perhaps less time than it took to get there, you have your life on the new place. Some of them might even be intelligent, especially if the advances are being directed. Un-natural selection. Point is, it’s a lot cheaper by many orders of magnitude than ferrying a small number of colonists from Earth and then telling them the won’t be a hospitable environment for them yet, or maybe ever except in this little box it made for them, which they’re used to since being stuck on a ship is all they know.I think it's likely that 'all of the above' style attempts will be made before we find out which methods of space exploration and development are the most successful based on whatever tech levels we have achieved at the time.
Classical physics is a function of the more fundamental quantum physics. They’re not separate branches of some yet to be discovered encompassing thing. QM encompasses classical physics just like relativity encompasses Newtonian mechanics.We can't change the laws of physics but we can learn more physics and start to know, as you do, that there are different laws of physics for the macro and the sub atomic. Classical physics laws and quantum physics laws, and the search for the physics that encompassed them both, is still for the seekers.
No argument except that it has little to do with the topic. Yea, we have an information device that’s always with us. Nobody say how that would revolutionize everything, including revolutionizing the whole concept of truth.I certainly would not be so short sighted as to jettison, in anyway, shape of form the very exciting and wonderful areas of VR, AR and holotech. A current mobile smartphone would not even deserve the dismissive term 'fancy telephone,' as it is obviously a palmtop/handheld computer and the connection to the technology called 'phone,' should have been dropped years ago.
Well there you go. Had you spelled it right, I would have accepted his reported assertions.Firstly, it seems I have the spelling of his first name wrong and its Leonard Susskind. — universeness
So I suspect, so I’m actually going with you not actually interpreting his comments the way they were meant.He is certainly no quack and is held in very high regard indeed, within the Physics community.
CFT is Penrose’s thing, no? No wait, that’s conformal cyclic cosmology.=1. Ads/cft (anti-de sitter / conformal field theory)

This is done today, but it’s not anything faster than light. Points 2 and 3 seem to just be suggested areas of exploration.4. Messages can be securely transmitted from the vicinity of one object to the vicinity of the other, without leaving any trace in the laboratory space between. Teleportation through the wormhole, 'so to speak.' This is not possible classically.
OK, that’s the part I balk at. Got a time stamp where he goes into that? Sorry, but an hour is a lot to me right now.He then goes on to exemplify 4, in a 'simple quantum teleportability' thought experiment, using an Alice and Bob type scenario involving qbits. As this developed, and due to stuff he states later on in the lecture, I began to think that, he was suggesting that superluminal communication, may not be impossible.
Not buying it. Utterly improbable odds.Spacefarers could meet, who have similar tech levels. — universeness
Star wars happen between two worlds both populated by us. That puts us both more or less at the same tech level. Another reason not to branch out to new worlds until you breed a less war-like creature to populate it.Carl Sagan stated often that in that case, there would be no Star Wars, as there would be no competition.
We’ve been technological for perhaps 3 centuries out of 1.5e8 centuries, so the odds are something on the order of a 1 in 7-8 digit number. Maybe 1 in 5-6 digits to find something to which you can communicate.What are the chances?
Depending on your assumptions, the chances of that one is 1. The long-odds thing was meeting one at an equivalent level of development. It wouldn’t be clear who would win in a conflict.Probably something similar to the chances of any sentient life forming anywhere in the universe.
I did at the time. Only in hindsight was it made clear, and then only because the news is supposedly free. What will the Russians tell their people if they have to withdraw, or if they annex this country that did nothing to them? There’s a lot more media control there, but the people can still read news from other countries. I’m from the USA and find one of the best ways to get actual news is to consult something foreign like the BBC. Every supposedly legitimate domestic news source seems to attempt to spin each story one way or the other.But we know not to accept such justifications
It’s getting far worse actually, mostly due to how people get their news today, which is by popularity picks by google or facebook or something. They push the stories that gather more clicks and not the ones that actually tell it like it is. Really, the social media thing has done more damage to general knowledge than anything I know. It isn’t just natural selection that’s making us dumber.Hopefully more and more of we will get better and better at not accepting fake news in the future.
First of all, conjecture isn’t an answer, it’s just a guess. If there’s no answer to know, then the omni thing must simply say that: I can’t say what the weather will be 6 months hence, despite my omnipotence. That’s the truth, it’s right, and the people asking are simply wrong to assume that there must be (however unknowable by science) exactly one answer that’s actually correct. It isn’t a requirement of the omniscient entity to know the right answer when there isn’t one.No right answer to know, surely suggests an invalid or currently unanswerable question or a question that can only be answered via unscientific conjecture, but so what?
I try to frame my opinions differently than assertions, but I sometimes come across wrong.If it's just my opinion, then I will say so. You do the same, yes?
Of course not, but besides the point. Is the positing of one even consistent? I don’t see why not. I don’t see a contradiction in the ‘no answer’ answer above.My conclusion is the same as yours, that no omniscient exists.
Didn’t you posit that all people are striving for this known unreachable goal? I didn’t agree with that. Sure, they maybe take steps to swim faster, but never with the goal of being the best really being a factor. Yes, they can aspire to it, but most probably don’t.I have merely further stated that if such terms have any use at all, it is a use of no more value than me being determined to win the 100 meters at the Olympics. I can at best asymptotically aspire to such and by doing so I might improve my fitness level but I will never reach that goal.
Had to look that one up. First I’ve heard it.A flippant steelmanning if you like.
Don’t understand. Why have a measuring device if the measurement is known before the measuring is done?The tech that the posited omnigod has, is manifest as god functionality, yes.
That’s what I’ve been saying that humans are particularly bad at. They focus on ‘my’ future, but little beyond that.I think we should ... focus on who we are as a species and what we want for our future,
The context of the ‘granting wishes’ phrase is the Cryonic one, not extending a normal life for a human. And in either case, one will be forced to come to terms with one’s own death.I think the phrase 'granting wishes' in the context you use it, is poorly chosen mockery of the (perhaps forlorn) hopes of currently live people, who face and have to come to terms with, their own death. — universeness
Well I see plenty for the individual of course, but I thought the subject of this topic wasn’t the individual. We’d have to eliminate aging, meaning that we’d stay young and fit for a long time. Last thing we need is 80% of the population in some kind of retired state. If we do that, we have to do it to everybody, and that’s kind of a problem with a large population. This would be a disadvantage for the species. There’s a reason evolution invented aging.I see many many advantages to vastly increased lifespan and robustness for living humans.
You say that like it’s some kind of benefit that a bigger number is better.then we can afford a population much bigger than the current 8 billion on Earth.
Longer life doesn’t make one smarter. A little more wise maybe, but not more intelligent. You can breed for intelligence if you like (something that is currently being naturally de-selected), but again, by your analogy of re-inventing the wheel, why do we need more intelligence when the tool already exists?People living for 500 years may offer a level of accumulated knowledge within some individuals that surpasses all past levels of 'genius.'
The 8 billion and growing count seems pretty precisely what is causing the environmental catastrophe. If there is some kind of purpose served by maxing out the number of humans that exist, trimming the population permanently down to around 6% of what is is today would be a great start. Less existing at once, but far more in the longer run.I think that such would indeed help prevent environmental catastrophe
Or better, to help the tech become that interstellar species. If you want humanity to make its mark on the universe, that is how to go about it.and provide advanced tech to help us become an extraterrestial/interstellar species.
Yea, what are humans good for if we can’t change the laws of physics? So put that on your list and jettison the VR thing which is just a fancy telephone.Yeah, you are assuming that the 'classical laws of physics,' will dictate what can and cannot be achieved in any future timescale.
Either you’re misreading his words, or he’s a quack. If his assertions actually said that and had merit, it would be huge news in the physics world. All of Einstein’s theories would get falsified and we’d have to reinvent a new theory to replace it. Time travel would become possible since I could observe something that hasn’t yet happened.The lecture I posted from Lennard Susskind earlier, has a section where he proposes that manipulation of quantum entanglement may indeed mean we can observe and measure what going on at large distances without any 'signal travelling,' involved.
That’s like you and me picking a random number from one to 10 million, and both of us guessing the same one. Odds are they’re either as developed as lichen, or we are the lichen in comparison to them. Neither might recognize the other as life, or at least not as something one might attempt to communicate with. Do we share our technology with the squirrels? The squirrels have picked a number insanely close to ours, but not the same number.If we meet alien lifeforms in the future that have the same or more or even a little less ability than we do
See? Time to first change who we are before we spread out and just make enemies of our colonies. Most every attack is justified as defense to its own people. Ever read up on what the Russians are telling its citizens about the Ukraine thing? Remember Bush and Iraq’s WMDs? “We’re doing this for defense”, not just to get back at somebody who insulted his daddy.I remain hopeful that the 'military advantage,' you highlight may well still be sought but will only ever be used in defence and NOT EVER to attack.
Sure, the farmer’s almanac does that, but it doesn’t say exactly where the rain will be falling at a specific time. Those specifics are what I’m talking about. Better tech has nothing to do with this.I don't value your example, as we can predict the weather in 6 months based on such as, last years data, combined with projecting any current weather patterns and climate change projections. — universeness
Not always, but yes. Theism isn’t based on logic or observation. They’re up front about that. Making impossible claims isn’t something that bothers them, and the people consuming the story have little interest in the self-consistency of the story.But that's a foundational claim of theism!
How so? A thing that knows all answers vs a question that literally has no right answer. Even a feeble intellect can detect something wrong with that.You are trying to contemplate an omniscient god with your feeble human intellect.
An omniscient has all possible tech or else it is not omniscient.
The two above statements seem to contradict each other. You apparently suggest that a god has a closet full of completely unneeded stuff. He’s a hoarder, unable to keep the place neat.Omnigod does not need a barometer, as it already owns all data/information in the universe, past, present and future.
So it doesn’t have a useless barometer in it’s closet, but rather has a useless barometer as part of itself, sort of like having eyes despite never using them. A human apparently strives to achieve a state where eyes and other senses are useless.All possible tech already exists as part of omnigod
Are you sure the TS hasn't taken place? One possible reason why we haven't met ET is because they don't want to (be discovered). — Agent Smith

Einstein wasn’t particularly well-studies. He had trouble with most of his schooling, which perhaps is a critique on the way education is taught. Einstein was unusually open minded, willing to question any intuitive bias.I accept that particular humans can excel in areas that they have studied for years in, and they can become 'better than most or even all, in THAT field, at THAT time.' I was probably better than Einstein at many many things. — universeness
Agree, but granting wishes to individuals has little to do with benefit to humanity except perhaps in a negative way.

Since they’ve never done it, there is also no evidnce that the information is lost. I think they’ve done it to other things. Amphibians are a natural at it and I’ve heard of some things (dinosaur almost?) getting revived briefly after a really long sleep. That story might be myth. Can’t find it now.I just think that there is very little evidence that whatever is stored in your brain, is preserved via cryogenic freezing.
Likely actually given we last long enough. Putting human parts in a machine (as opposed to putting machine parts in human) seems inefficient. All this life support to do something probably better done without all the extra overhead.Well , If I wonder if there will be 'points of merging,' in the distant future that augments humans into some genetic/cybernetic merge.
We have that now. It’s called a TV and phone. Neither works faster than light, so no VR is going to let you walk around and control some avatar light-years away. Still, the military does that with drones and such because the distances are not so far. Even doing at the moon would be awkward, as are communications with those long pauses.Holotech may be a great way to project yourself great distances, very quickly, for communication purposes or even as a way of investigating planets without travelling there yourself, physically.
You said humanity, in context of something to which a thing has a purpose. The less specific thing would be a collection of agents, humanity being only part of the larger collection, to which the thing has collective purpose.What do you mean by 'something less specific?'
One race would be likely far advanced compared to the other and would have little to learn from the lesser, at least as far as technology is concerned. The lesser race would likely not be ready for ‘all the answers’ at once, and so if it is deemed reasonable/safe to bring this lesser race up to speed, it would probably have to be done quite slowly. Remember the main reason for advanced technological development. It isn’t for exploration or for fantasies about omniscience. It’s about military advantage. You don’t give super-advanced toys to a race like that. That’s part of the transhuman effort: To collectively change who we are so we can survive our own advancement.If we met another alien race and we 'pooled' our science instead of trying to wipe each other out, would that not help all concerned answer all the tough questions we have?
Cannot be known, and I gave examples. The weather 6 months hence was one.If you believe that there are things that can be known then we diverge there.
Well, the Korean thing has to end eventually. The death of somebody with absolute power instigates a struggle to replace him, and one of them eventually won’t know how to hang on to the power."There have been tyrants and murderers, and for a time, they can seem invincible, but in the end, they always fall. Think of it, ..... always!”
Wasn’t an irrational statement. Under several interpretations, it’s entirely true. The future weather is in superposition of all those states. It isn’t measured by us, and under several interpretations, measurement by something not part of the structure isn’t meaningful. So if the definition of omniscience is that the entity must know this unknowable thing, then the only logical inconsistency is the positing of such an entitiy.But why would an omniscient make such an irrational statement about the weather on July 1st 2023? — universeness
Really? God needs a barometer to measure the pressure? Tech is only to tell you something you don’t know, or do something you can’t do yourself, and the omniscient omnipotent entity doesn’t need any of it.An omniscient has all possible tech or else it is not omniscient.
Not so. Persecution cements faith which otherwise tends to stagnate. The Christians were never stronger in their belief than when they had to hide it from the laws at the time. It kept them unified too.One would think after being inhumanely treated for so long, their spirit would be crushed — Agent Smith
Fine, but the desires of the individual does nothing to help humanity in the way that the transhumanists envision. All it does is drain limited resources for no useful purpose except that of the gullible sot that paid for it.I consider cryonics a valid act of desperation — universeness
That wager begs its conclusion. Pascal didn’t think it through.Personally, I would have more confidence in cryonics than I would in Pascals wager.
Cryonic tech. The LHC uses cryogenic tech, but has nothing to do with bodies.I am not sure what you mean by this, unless it's just to confirm that you don't think the cryogenic tech would work
Again, what goal of humanity is served by the holo-deck? It’s just entertainment, not it being used for the sort of goals you’re describing.I think it depends on whether or not VR and AR can grow into something more akin to the type of 'holography' we see depicted on shows like 'star trek.
Pretty much by definition, when humans can no longer breed with one. What if we create a species that does not breed the ‘normal’ way? Only test-tube high-tech artificial reproduction. Much of the flower industry already works this way.At what point will 'transhuman' efforts result in a new species?
Absolutely, just as much as a human with tooth fillings. By my definition above, I am no longer human, but that’s just me. I used to be. Have proof.Is a human kept alive by a pacemaker, still fully human?
The workings is something of which there is more to learn. As to purpose, that word seems reserved for something serving the intention of some entity, thus serving a purpose to that entity. So say I drop a jar into the sea and some octopus (yes, them again) moves into it as a sort of home. That’s purpose even if the octopus didn’t create it. So in that light, the universe seems to serve the human purpose of providing materials and environment for our existence, but that’s our purpose being served, not that of the universe, which would be akin to the jar requiring to have an octopus live in it.I am currently most attracted to 'asymptotic intent and purpose towards omniscience, with the goal of knowing the workings and purpose of the universe. — universeness
This came up before but I still don’t have your definition of free will, especially one where it subjectively matters one way or the other.I also now see free will (if it truly exists) as not gifted from god but as a result of intent and purpose
I think that would be humanity that knows stuff then. Maybe something less specific if there’s more than just humanity doing the collective knowing.Can such as the concept of country you are suggesting, be expanded to 'planet'? or solar system or interstellar existence, if such was the spread of humanity in the future.
There are things that cannot be known, so this asymptotic approach cannot be.he term asymptotic is important in my suggested human aspirations towards omniscience. — universeness
Worked for the church for a long time, and it works indefinitely in the Korean situation as long as freedom of speech and information is kept in check. The church failed to keep it in check.I accept that you can use terror to indoctrinate people, especially if you start when they are young, but its a very old tactic that fails in the final analysis.
OK, the omniscient entity can say that it will rain next July 1, and also it will be dry and sunny, and also cloudy and humid, and also reasonably cool, not none of that all at once. But I could also say that, and we’d both be right, and we’d both be entirely unhelpful. More tech isn’t going to help with the answer precisely because the answer above is already correct.If you accept the definition of the term omniscient, then such certainly could do what you suggest it could not.
Depends on definitions, but yes. I don’t think the church suggests that God has or needs ‘tech’.I think there is some contradiction here. I think both of us give high credence to the assertion that god has no existent. Would you agree?
I don’t think they’ll find themselves in each other’s presence much if at all. Putting super-people here on Earth will just cause wars. Putting something different on planet X is a necessity.No doubt their will be issue's of human V transhuman, rights, racial status, redundancy etc.
As I said, humanity hasn’t exactly shown its readiness for tolerance of something different. Recent events have shown that such prejudice is always there under a thin layer of civility.I can only hope we do better than we do with issues between black/white, male/female, ability/disability, gender variation etc.
If there’s anything a cephalopod can do, it’s shape shift. Color shift too.Well, I would probably prefer our science to have reached polymorphic (shapeshifting) tech:
That started long before there were mammals.The cognitive singularity: Mind from life (primates, dolphins, etc.) — Agent Smith
You’re using ‘singularity’ in a different way than is meant by these terms. Until machines write better code than people do, the TS hasn’t taken place.the TS (the technological singularity) might've already taken place — Agent Smith
The transhumanists are actually on some of the right tracks, but need to address some important roadblocks.Transhumanism does have currently running science projects. — universeness
That wasn’t listed as a premise. Are we starting anew with the ‘proof’ or are we steering away from the subject? What system is doing the knowing here, because I cannot think of a way in which this can work. My country doesn’t know most of what I know for instance, despite me being part of the country. Any yes, a country, unlike say the universe, is arguably something that knows stuff.I don't see these as separate premise's to my main premise that 'humans are a way for a system to know how and why it IS, from the inside out.
OK. I give very low credence to people aspiring to being omniscient, like I can’t think of anybody besides you who might agree to such a thing.I have already stated that I am interested in what percentage credence level, others would assign, to what I am typing in this thread.
Well, they encourage it with impossibly high stakes with which to multiply the otherwise low probability claims, and of course there’s also the indoctrination since early childhood. I mean, the N Koreans really do believe KJ Un is a god and the west is poised to destroy them at any moment. It’s not that they are low intelligence over there, but rather that they’ve no evidence to contradict that. The purpose of the claims is not to be an explanation or to be an actual best attempt at truth. Neither has the same purpose as science.[Theists] ask for high credence levels to be assigned to their claims all the time.
And yet knowing where the next dot will land in a double-slit setup can no better be known 1000 years from now than it can be today. Ditto for the weather next July 1. But then, given certain interpretations of QM, not even an omniscient entity could make either prediction, which is sort of contradiction, no?Knowing the speed of light in a vacuum to the nth decimal point is 'impossible,' if you make n big enough.
Almost by definition, yes.The fact that no information is conveyed to us by this (proposedly) existing entity, suggests it does not exist. — universeness
Already answered that. Because we need to know it as well.what is the point of us learning stuff, if we are merely finding some stuff out that this god already knows.
Why would you aspire to creating a wheel, if a wheel already exists? — universeness
You asked why we should create one, not why we should invent one. I should invent one because I have no access to (or even knowledge of) the invention made by the guy a month’s walk from here.No, the question becomes, why are you having to reinvent the wheel?
If a supernatural entity provided me with all my needs at all times, I wouldn’t need the wheel. For that matter, I wouldn’t need senses, or kidneys, or anything else. I think heaven is supposed to be that sort of torture.why did the existing supernatural not just provide you with a wheel?
It is fallacious to go from merely ‘unhelpful’ to ‘nonexistent’.Why do humans have to reinvent tech that god already has? Unless, this god does not exist and therefore has no intent or purpose.
Interstellar space is not an environment in which the human animal has evolved to thrive. We’ll need to change into something else to be fit out there. That’s the posthuman thing they talk about in the transhumanist literature. Point is, post-human isn’t human anymore any more than we are still a rodent.If we are not existing in interstellar space within the next billion years then we deserve to be extinct imo.
I’m kind of all for it, but for the social issues I brought up at the top of this post. It’s considered immoral by many.I don't mean that natural evolution ever stops, I just mean that science tech will have a much faster effect and can be fully controlled via intent. Our manipulation of agriculture and domesticated animals is proof of that.
So if we find a possible wet planet best suited to something like an octopus, and we instill similar/better intellectual ability/identity and physical functionality (they’ve already got most of all that), but still essentially a cephalopod by DNA, you’d be OK with calling it human? It’s a word that indicates capability and not primate lineage at all?'Human' is a template, do we need to be so precious about it? Are the aesthetics of being human, as important, as having the same intellectual ability/identity and physical functionality of being human?
Death by age is an adaptation added to certain branches a long time ago due to its benefits. It enabled the very complexity that you’re trying to encourage in these post. Sure you want to take that away? I agree that some extra time would be nice to help increase the productive-to-education time ratio. Humans become adults now almost a decade later than they did not too long ago.I would welcome increased longevity
Engineering a new form isn’t done to you. It’s done to a new generation, so the question is, would you accept your kids for what they’ve been engineered into?It would depend on the existence of others who were 'like me' or who were willing to 'accept' me for what I had 'become.'
I was basing my words on descriptions like:
“… Despite their vast separation, a change induced in one will affect the other.”
That space.com quote is wrong, but typical for a pop article actually. jgill gets it closer. Measurements (in the same way) of each of entangled particles will be found to be correlated when later compared. I’m fine with the wiki * Caltech quotes. Neither suggests that a change to one affects the other.
— universeness
Some non-local interpretations (Bohmian mechanics) suggest such communication.My main point was that I don't think any information travels between the two when a measurement of one or the other is made.
That was a long vid. Haven’t the time to look. Does it make predictions? Is there a falsification test for his idea vs the consensus? Is there even a consensus quantum gravity candidate yet?If Lennard Susskind is correct Quantum entanglement may BE gravity!

Ah, ‘near the equal’ like there is some sort of single scale by which nothing else measures up. You name all these human things that other species haven’t done, but ignore all the marvels that other species do that humans have not and can not.Did any of them reach the scientific knowledge we have or created tech which is anywhere near the equal of ours? — universeness
Number 2 doesn’t follow from the first premise, so I take it as (two) additional premises. I’m willing to accept them, but additional premises weaken an argument that the first premise is sufficient. I’d like it better if premise 2b was that there is no evidence of gods. The comment as worded leaves it open that there is an omniscient god that isn’t involved in the creation of anything.The reasons [that question-asking precludes an existing god] are:
1. We ask questions
2. We demonstrate intent and purpose, that can significantly change our surroundings and potentially, the contents of the universe. There is no evidence of god(s) creating anything.
This is a 4th premise now, and one I don’t accept. We cannot aspire to an impossible state. We ask questions because we’re in present need of information, not because we have some impossible goal.3. We aspire to the omni states, because they do not currently exist.
Because I need a wheel to move my stuff and the existing wheel isn’t accessible to me. The question seems to presume there is no need for two of anything, even to the point of two people both knowing the same fact.Why would you aspire to creating a wheel, if a wheel already exists?
Well, it depends on one’s definition of ‘exists’. I hold a definition that involves measurement by a specific thing, so indeed, absence of measurement is nonexistence relative to that thing by that definition, but most people use a different definition.This is an example of where a statement such as 'absence of evidence is not evidence of absence,' fails.
Free will is another thing with all sorts of definitions. I define it as not being remote-controlled (possessed) by some external entity. An example is a slug that gets some parasite that makes it change color and sit in prominent places and wiggle enticingly, in violation of the will of the slug. It lacks the free will of an unaffected slug which is in charge of its own sluggy destiny. Again, that’s just my definition.Free will, if it truly exists, is a natural happenstance, it was never given to us and its consequences are emergent.
Scapegoating the gods has a purpose, but probably not one that serves humanity as a whole.Time for humans to stop scapegoating gods and take full ownership of free will and emerging capability.
Given that our planet will not be fit for multicellular life in about a billion years, where exactly should we do this existing, and how will we still be human if we change enough to be fit for that place? It’s not like star trek where 80% of planets are ‘class M’ meaning we don’t have to burden the wardrobe dept with making space suits today. If we can terraform some other world, what’s stopping us from terraforming Earth back to where it’s an environment where we’re fit?Human's could exist for many many 'billions' of more years.
They admittedly seem rather bent on forcing the issue given their public policies. I have to admit extreme cynicism when it comes to religious leaders and pundits. It seems incompatible to hold a top position in organized religion and also hold to the beliefs taught, which means they’re not actually trying to force God’s hand with the dangerous policies.How long will the theists tolerate the complete absence and silence of their supernatural superhero?
I don’t mean the word by the definition you quote. I simply meant not-dualism, no supernatural mind.Monism is a term from philosophy — universeness
No, I didn’t see any link, but it was pretty easy to search given what you posted. I watched it.What do you mean 'No link provided'? Did you not see the video I posted by Jim Al-Khalili about how quantum physics is employed in the biological world? — universeness
So it does, but if you copy and paste it into a url bar, it goes to the right place. Is the linking messed up on this site?When I clicked on the link you posted, it took me to the OP of this thread??
This is not true. Not sure where you’re getting your physics. Again, a message could be sent faster than light if this was true.A change in one IS immediately experienced by the entangled object
Don't get the last bit. It would seem that if you measured something's location, it is the location possibility which gets reduced to some much smaller deviation, and the others (momentum say) which are still just probabilities of what will be measured. The first bit talks about 'existing in a specific place' which is counterfactual terminology. Most interpretations do not hold to counterfactual definiteness, which means particles don't have actual positions (and other properties) in the absence of measurement. BM would say a photon exists en-route. Just pointing out the minefield of using terms like 'exists' which are defined differently from one interpretation to the next.That prior to observation the particle doesn't exist in any specific place, that its possible properties are described by the wave-function, and that the act of measurement reduces all of the possibilities, except for the one in which it was measured, to zero. — Wayfarer
The measurement changed the wavefunction (relative to to the screen at least), so yea, that was caused by the interaction. Did the measurement change the photon? No, it's more like the photon caused the measurement. I'm trying to see the problem here.So that's how the act of observation is considered causal. Is that not correct?
Don't know much about QBism, but it sounds a bit like all the idealism stops being pulled out. It defines existence in terms of beliefs and such, if I read it right.I don't recall reading anything like that about Bohr and Heisenberg's interpretation, it seems more like QBism which I mentioned above.
If one is seriously averse to wave function collapse, the list of interpretations on wiki (about 13) has only half of them supporting collapse. Point is, there are others to choose from besides MWI.Might I suggest that the motive for accepting the MWI interpretation is to avoid the philosophical conundrum of the 'collapse of the wave function'? — Wayfarer
OK, this is like a double slit setup with a which-slit detector behaves differently than a setup without one. That's not especially profound. If you get into the act of observing now changes something in the past, that's quite interpretation dependent.to wit 'The observer effect is the phenomenon in which the act of observation alters the behavior of the subject of observation'
Again an interpretation dependent statement. Not all interpretations suggest that a thing an exist in multiple states simultaneously. Bohmian mechanics for instance has but one state for anything. It is a hard realist interpretation where stuff is where it is. On the other hand, it necessitates backwards causation where decision not yet made can affect what a particle does now. I personally find that more offensive than collapse.This is due to the ambgious nature of sub-atomic particles, which means that they can exist in multiple states simultaneously.
Causing what to assume a definite state? The particle? Only some interpretations suggest this. With some (original Copenhagen for instance), the wave function is epistemological, describing only what one knows about a system. You take a measurement and your knowledge of the system changes, but the system is not affected by your acquisition of this knowledge.When an observer measures a particular property of a particle, they are effectively collapsing the wave-function of that particle, causing it to assume a definite state
Something you apparently consider a substantial cost. I'm fine with that since I don't hold to the premise that there should be only one world, especially in the absence of evidence supporting that premise. My dismissal of MWI comes from other grounds.The approach of the MWI is to declare that the so-called wave-function collapse doesn't occur - but at the cost of there being many worlds.
Humans were not the first to do this. A huge extinction event 2.7 BY ago took place upon the emergence of Aerobic Metabolism, wiping out or at least driving into hiding the prevalent anaerobic life at the time. That dwarfed the change that humans so far have had on the planet. It wasn’t particularly intended, but neither is what the humans are doing.Remember, my 'objective truth' candidate is now life that can demonstrate intent and purpose to a minimum level of being able to affect it's environment(planet) (and potentially its interstellar neighbourhood) in the same way we humans can. — universeness
Remind me of the reasons. I seem to have missed it, unless the question-asking thing is it.I think [Purposeful life precluding god] does follow. I have already given my reasons. What's the point of asking questions, if god already has all the answers?
I just don’t agree with this connection. I have no trouble envisioning question-asking in a setup with a god.WHY? If god exists, we would not experience such compulsions.
Yes to that.Consider yourself excused! I am glad you agree people have purpose! Do you agree that god is not needed to produce such a property of life?
Makes suffering sound like a bad thing. If I could take a pill that removed my suffering, I’d not take it. And as I said, they seem to advocate only the extinction of antinatalism.They advocate for their own extinction as part of their goal of ending all suffering, based on their convoluted moral imperative.
I don’t think that is within the realm of human capability either, even if we do manage to trim over 80% of the species. Life will continue, being exceptionally difficult to stamp out. I don’t think another Theia event would suffice.Well, perhaps I went too far by referring to destroying the universe. I am happy to restrict their threat to life on Earth.
Agree to all, but with the implications of being useful/functional to the people. You go from that to “the bus knows itself”.The intent of the people on the bus dictates the direction of the bus and therefore the bus is 'useful,' has a function,' 'SERVES a purpose'. — universeness
I think I was asking about the purpose of humanity, as opposed to the purpose of humans/people, something which I’ve acknowledged.So yes, the purpose and intent of rabbits is a poor comparison with the intent and purpose of humans.
Didn’t understand any of that. Maybe I should say naturalism: The lack of need of supernatural to explain what happens.I think the term monism has weaknesses. Priority monism or the concept of existence monism, can be used as arguments in support of god, such as in BS ontological arguments like the Kalam cosmological argument. I am monistic in the sense of the credence level I assign to the existence of, and the search for a t.o.e.
Logic gates are not fundamental in the way that quarks are to matter. Gates are made of transistors and other components for instance. I was roughly equating a gate to a neuron, both classical constructs with classical behavior. This seems to be the fundamental of consciousness, despite your assertion otherwise. As I said, the same function can be performed by a different sort of switch with similar results, the China-brain being a sort of thought-experiment on the subject (not to be confused with China-room which is something else and fairly fallacious).Logic gates and binary are fully understood and are as 'fundamental' in computing as quarks are in physics. We don't yet know the fundamentals of human consciousness.
My opinion is otherwise. Neither statement constitutes evidence one way or another, but one can always choose to never apply the word to something nonhuman. It sparks fear in me if we ever encounter an alien race because of the tendency to refuse to apply human language to anything non-human.The distinction is that current computers have no self-awareness and do not demonstrate any ability to 'understand.
Plenty of evidence to the contrary, else things like ChatGPT wouldn’t know when to apply the operation. Not all computers add in binary. I had one that didn’t. Not all humans do math in decimal, myself included sometimes. Sometimes I do calculus in analog (kind of like a bird does), which gets results faster by orders of magnitude.In binary addition, 1+1 is 10. A human and a computer can both do this calculation but only a human 'understands' it.
A computer has no more awareness of that than you do of a specific nerve firing.A computer processes 'on' + 'on' as two closed gates representing two 1's in the binary 'units' numerical column and produces an open gate in that column and a closed gate in a representation of the decimal 'two's' column.
That it is.IT IS A BRAINLESS MACHINE!

Don't know how to answer this. All interpretations are supposed to yield the same empirical results, so if there is an empirical problem to be solved (like getting a quantum computer to work), the problem is with quantum theory.What in your view is the problem for which MWI is a solution? — Wayfarer
MWI is and isn't a realist interpretation. It, like any almost all interpretations (QBism included), does not hold to the principle of counterfactual definiteness (that things really exist in the absence of measurement). Only under that principle is there 'spooky action at a distance", or faster-than-light cause/effect.It is just that the interpretation actually does not say anything whatsoever about reality. — Quanta interview
Such a statement can be crafted of any interpretation.Whenever a coin is tossed (or any process occurs) the world splits. But who would know the difference if that were not true? What does this vision have to do with any of the details of physics? — Qanta
OK, I’m mostly familiar with the list, but it seems to only apply to that already designated ‘biology’, leaving it open as to whether the thing in question is biological or not. How about a computer virus that mutates on the fly? It arguably doesn’t grow. I can think of forms that don’t reproduce.Yeah, I broadly agree with the 7 criteria from biology:
In biology, whether life is present is determined based on the following seven criteria — universeness
Now we’re asking if it’s intelligent, not if it’s life. Something can be either and not the other, so it’s a different question.I give a very low credence to some lifeforms proposed in sci-fi such as 'The Q' is Star Trek or the various 'energy only' lifeforms but then again, if such turns up and demonstrates abilities such as sentience, awareness of self, ability to communicate, intelligence, ability to do science
Doesn’t seem to follow. Most argue the opposite, that it is the god that supplies the purpose otherwise absent. Your proposal of inherent purpose is equivalent to that of objective morality without involvement of actual commands.the proposal is that due to the fact life has intent and purpose, there can be no god.
Excuse me, but I never said I (people in general) didn’t have purpose.Doomsters and pessimists are wrong, as life with intent and purpose is compelled towards progressing that intent and purpose.
Really? Like to see them try to make a dent in it, positive or negative. We can perhaps take action that will ring through the galaxy, but further? The universe?? That’s not even allowed by physics.I understand that individuals can have intent and purpose to 'destroy the universe,'
What is an antinatalist to you? You bring it up a lot. Do they propose letting the human race go extinct by not having any kids? All that will do is make antinatalism go extinct, sort of like the Jim Jones colony.Antinatalists are wrong because life happened in the universe and would happen again if it went extinct.
No idea what you suggest by this. An example would help. A bus hasn’t intent just because everyone on it wants to go to the same destination.Life changed the universe into a system which contained intent and purpose. A demonstrable ability for a system (the universe) to know itself from the inside.
That’s what’s in a human name. Not sure how this was relevant to my text to which it was a reply.There is no evidence of rabbits memorialising science in the way we do and passing such on to the next generation of libraries. WE coined the name Rabbit. They did not coin the name Human. What's in a name? Human intent and purpose! — universeness
This isn’t a physics forum, but that’s a fun one to refute. How fast must a ping-pong ball hit Earth (from space) to come out the other side? OK, the ball doesn’t come out intact, but neither does the Earth.A hammer made of candy will never break a stone wall not matter how often you try.
From one monist to another, there is no hard problem of consciousness.The hard problem of consciousness remains
OK. I thought you were attempting to justify it, not just put it out there as a premise.The proposal numbered 4 is asserted before the asserting that humans demonstrate intent better than any other species on Earth does. I don't see the logic problem you are trying to establish here. — universeness
Whereas the logic gates in a computer require no more complexity to do whatever they do? I mean, there are more parts than just neurons and logic gates to both things. Humans neurons for instance are very sensitive to chemicals. Logic gates are very sensitive to supply voltages, but the latter doesn’t gather information from said voltage variances. In the end, both are machines made of simple primitives, an argument that doesn’t preclude an arbitrary complex process from taking place. This bit started from your assertion that computers cannot be information processors, but I’m looking for the distinction that makes this so.It may not just be neurons firing, that's the point. There may be much more complexity involved.
I am on that list as well. There’s no evidence that neural activity in any way leverages quantum indeterminacy. I mean, it leverages quantum effects since matter cannot exist in the first place without quantum mechanics, but what a neuron does can be done (very inefficiently) with levers and gears and such. It’s a classic process. There’s no information to be had in quantum measurements, else creatures would long ago have evolved mechanisms to take advantage of it.I know 180 Proof and others do not assign much credence to the idea that quantum effects are an integral part of human consciousness
Tunneling is. Just like transistors, it is used to get a signal through what would otherwise be an impenetrable potential barrier. But as I said, that can be done less efficiently with classic means like say relays or railroad trains.I am not so sure I think quantum fluctuations, entanglement, superposition and quantum tunnelling may well be involved in human consciousness.
I must refute this assertion of yours.You sound like a nice person noAxioms!
Not sure exactly what he suggests or how he words it, but there seems to be problems with two different universes (one with each measurement) existing. If there's all these universes/worlds and they exist, the more probable ones either have to 'exist more' than the lesser ones, or maybe there's just more of them. What does it even mean for one thing to exist harder than another?Sean Carrol, a current proponent of MWI, talks of universes splitting. — Marchesk
Hossenfelder indeed seems to find issues the interpretation. This seems to be part of a series taking down each of the interpretations in turn, with a similar argument.
