• Eternalism vs the Moving Spotlight Theory
    Eternalism does not suggest that every state of a person along his worldline experiences every time in the worldline. That would be empirically quite different, wouldn't it?noAxioms

    Well I just gave an alternative idea for eternalists in the stage theory. Though apart from that, I wasn't suggesting you were saying that I am experiencing every moment of my life at every part of myself. You were suggesting that I as a whole am experiencing every moment of my life, which is obviously false cause I am not experiencing every moment of my life.
  • Eternalism vs the Moving Spotlight Theory
    Ouch. Under eternalism, we beings are worldlines, and experience every moment along that worldline.noAxioms

    Or alternatively we are stages which are located at a single instant and experience only that one instant of time while other counterparts experience the others. You know, cause experiencing every moment has the whole obviously wrong thing going on with us experiencing only one moment.
  • How will Bernie supporters vote if Biden is nominee?
    More Sanders voters voted for Clinton in 2016 than Clinton voters did in 2008 for Obama. I imagine the same will happen this time around given the stakes. Trump is right now plunging the country into a health and economic crisis through his carelessness and incompetence. I can't imagine that that would be easy to ignore.
  • Intuitions About Time
    2 is more of a comfort to believe, particularly considering the relativity of time, and the uncertainty it lends to our notion of reality. In my opinion, it is 2 that’s a cop-out, and 1 lines up better with quantum relativity as I understand it (Carlo Rovelli’s ‘The Order of Time’ outlines this quite well).Possibility

    It all depends on how you choose to interpret both theories. 2) has trouble if you understand quantum mechanics as being inherently indeterministic as it is traditionally understood, but there are other interpretations that don't involve fundamental chance. Similarly 1) has trouble with the traditional interpretation of relativity, but that isn't the only way to interpret the theory and there are versions of the theory that incorporate an absolute order of time.

    All this is just to say that the science is unclear when placed in a philosophical context. Hence why I roll my eyes when people talk about "science vs. religion", as if there is only one religion and one scientific way of looking at the world.

  • Joe Biden (+General Biden/Harris Administration)


    All Biden has to do is just not be horrible and despised like Clinton was in 2016. The democrats are prepared to vote for a paper bag if that means Trump doesn't get re-elected. The election will largely be decided by how much the left is willing to turnout to vote for the democrat.
  • Joe Biden (+General Biden/Harris Administration)
    It's a rerun from 4 years ago: choosing between two evils.Benkei

    To a certain extent, but I don't think that the democrats could've run a more reviled candidate than Hillary Clinton in 2016. She was unpopular among republicans and democrats and though I much prefer Bernie than Joe, I can't say I hate him on a personal level like Clinton.
  • The Road to 2020 - American Elections
    Or more likely said, if the responses to corona-virus crash the Global economy.ssu

    Yep. But it seems as though world leaders are caught between a rock and a hard place here in responding to the epidemic. On the one hand you have China and now Italy quarantining entire cities which is obviously gonna cause damage to their economies, and then you have Trump downplaying and lying about the situation to save his reelection bid, leading people to distrust their leaders to do anything and causing widespread panic, which is also bad for the markets. And I imagine that panic and distrust will only get worse once the actual testing kits gets put in place and people in the US realize that there are far more cases than they were able to find before.

    The threat of the virus itself on actual people is overblown as far as we're concerned, but the threat to the economy is very real.

    He seems pretty sharp to me. Blew up the Republican party then blew up the Democratic party, confounding the experts and beating the "inevitable" Hillary. Survived three years of everything the "#resistance" could throw against him. Unleashed the most vibrant economy in the world. Stood up to China. Didn't start any new wars.

    You call that senile. That makes you look like you have your hands over your eyes while you shout insults at a guy you don't like and whose achievements you won't recognize. Or as it's called, Trump Derangement Syndrome. You got it bad.

    I don't see how any of that requires a sharp mind. Beating an incredibly unpopular politician, having a cult following and a congress that's willing to put party over country to protect your ass, and inheriting a great economy that's already been growing for years doesn't require a very stable genius.

    It shouldn't be controversial to say this: Trump is a f***in corrupt moron.
  • The Road to 2020 - American Elections


    It's also because young people didn't show up. I'm sorry, but as much as young people on here may complain about the way things are, they're to blame for Bernie's loss more than anything. They just didn't show up on Tuesday when they had a progressive option, and the moderates did turn out in big numbers, which says alot about the state of things.
  • The Road to 2020 - American Elections
    One interesting take I read is that the Dems might have been wrong to coalesce around Biden. The GOPs failed to coalesce to stop Trump, but Trump won the general election. There's something to be said for that. Getting behind senile and corrupt old Joe will be a disaster.fishfry

    To be fair, if senile and corrupt were things that would disqualify someone, then Trump wouldn't be president right now.

    I doubt that Warren dropping out would help Bernie much at this point. It could've helped in Super Tuesday if she dropped out and endorsed him like Pete and Amy did but that ship has sailed.

    Anyways, I think we have to hand it to Warren for ending her campaign the way she did. She ended up abandoning her friend when he needed her most, going back on the values she claimed to be fighting for by kneecapping the progressive movement and taking superPAC money from an oil lobbyist that clearly only had an interest in her role as a spoiler, in a delusional and selfish attempt to win the presidency via. stealing the nomination on a second ballot and potentially fracturing the democratic party in doing so, and what did she get from all that? Losing in her home state and coming in third. I can't think of a more worse and embarrassing way for someone to end their political career and I consider her to be the biggest loser of the night, second being the billionaire who spent $500 million just to turn himself into a national laughing stock.
  • Does Relativity imply block universe?
    It's often said that Relativity entails the block universe, or eternalism, or the B-theory of time (whatever you call it), but that's a common misconception, as much as the idea that Quantum Mechanics entails indeterminism.

    In the latter case, indeterminism only holds for the most widely adopted interpretation of QM, the Copenhagen interpretation, but there are others. For instance, one can preserve determinism by incorporating some form of non-locality, as in Bohmian mechanics. One can also introduce multiple parallel universe as in Many Worlds as well. They're all equally valid ways of understanding QM as far as the scientific theory goes.

    Though less well known (perhaps on account of the fact that Relativity isn't notorious for having 100 different interpretations unlike QM) the same goes for both SR and GR. One can introduce a preferred frame (or foliation) to designate an absolute sense of time, and that'd be compatible with the scientific theory so much as it doesn't make any differing empirical predictions. In fact, one of the predecessors to SR was an empirically equivalent model that included an absolute frame called the Lorentz Ether Theory. With respect to GR, there are also alternative formulations like Shape Dyanamics which incorporate an absolute time in exchange for absolute scale.

    Of course there are questions about whether we should introduce such additional structure in the first place to account for our traditional sense of time, but that's a question of metaphysics, not physics.
  • Why We Can't solve Global Warming
    Increased temperatures, increased flooding, mass migration from sea level rise, increased droughts, more extreme weather events, water shortages, etc. You know, the things that scientists have been warning about for years but older generations couldn't be bothered to care about.
  • Why We Can't solve Global Warming
    If global warming is a fact and I suspect much of the research on it is done in the west, specifically the US, why has dear ol' Uncle Sam not taking the lead on the issue? If I recall correctly the US as recently as a few years ago pulled out of a climate accord. If the most well-informed of all nations behaves in such a callous manner what can we expect from other countries whose economic engines run on fossil fuel?TheMadFool

    Just because the US is the country that produces alot of significant scientific breakthroughs doesn't mean that the US population, and the elected officials chosen by that population, are the most well informed.
  • Why We Can't solve Global Warming
    As a young millennial I'd have to say that the problem of climate change terrifies me greatly, but I do try to be optimistic about it (cause honestly I feel like we all have to be).

    At this point, I have no faith in the abilities of government bodies alone to be able to tackle the issue properly. They've had decades to address the problem and very little to show for it, and when we currently have psychopaths like Trump, Bolsonaro, and Morrison in office, I don't feel like that's gonna change anytime soon.

    So much as there will be positive developments I think it'll come primarily from technological breakthroughs in green energy and other technologies like carbon capture which will provide an economic reason for people to get off of fossil fuels or at the very least cut their emissions, cause apparently that's all that matters to people. We're not gonna see any real changes until that happens, and thankfully there have been some promising steps toward that direction. My only hope is that by the time we do adopt solar and wind as our primary energy sources that it won't be too late to stop the worst of climate change.
  • The "Fuck You, Greta" Movement
    Yeah and those economic incentives likely will have to come in the form of taxes, at least in part. That could work, one problem with that route though, is that those taxations often hurt the poor the most.ChatteringMonkey

    I think you misunderstood what I meant. I was referring to the fact that technological developments will help give companies and countries more of a reason to switch to renewables over relying on traditional fuels since they will be cheaper and less costly overall on a financial level. Like I said before, these technologies are becoming competitive and will take over in the coming years. My only hope is that it will be sooner rather than later given the limited time frame we have to act on the environment.

    One reason why I liked the vanilla Green New Deal was that it can be argued both on an economic and environmental level. Even if you have people on the right that don't care/believe in climate change, they can still be persuaded on the economic opportunities of green technology. So much as governments are involved, I think they should in part be investing and subsidizing R&D on renewables and EVs, especially if it moves funds away from fossil fuel subsidies.

    Anyways, since we're on the topic of taxation, it really depends on what the taxation is. If it's gonna be regressive like the ones in France, then of course that's a backwards way of going about it since it disproportionately hurts the poor over the rich. A carbon tax that is rebated back to the people like in Canada would be more palatable IMO. In addition, there are also tax credits that incentivize people to switch to EVs and renewables that should be considered as well.

    I'm not a huge fan of public shaming. Psychopaths typically don't feel shame. And more generally, I don't think shaming changes the behaviour of people for the better usually. You give an incentive to people to hide their behaviour yes, and then another layer of bad gets pilled on top of it.ChatteringMonkey

    Shaming of public officials may not sway their hearts on a personal level, but if it hurts their public standing so as to hurt their businesses or reelection chances then they'll be obligated to act whether they want to or not. Bolsonaro clearly doesn't give a damn about the Amazon burning, but the global outcry of the Amazon's destruction led to organizations like the EU to reconsider their trade deals with Brazil which convinced him to finally send in the military to put them out. Of course this isn't gonna stop him completely but it helps limit the damage he is doing.
  • The "Fuck You, Greta" Movement
    One of the problems on the policy half of the question is that it's a bureaucratic and political mess to get something done.ChatteringMonkey

    Indeed, it sucks to get consensus on any issue, especially this one. That's sort of the reason why I have less faith in government bodies to change things given how democratic systems can simply elect psychopaths like Trump or Bolsonaro at any point and turn it's back on the whole climate fight. It wasn't that long ago that the US and Brazil were seen as leaders of the environment and now things have turned around. They've had a chance to do things for decades now and we're still figuring it out.

    Likely we won't be seeing massive change until an economic incentive comes in to push people to switch to renewables, cause apparently that's all that people care about. Thankfully renewables have become competitive and electric vehicles are catching on so there's hope on that front. I just hope that people start adopting it en masse like they did smartphones.

    And then what does it help really, to keep shouting and blaming everybody?ChatteringMonkey

    Public shaming for one. Protests have been effective more or less historically. And it's not like she's wrong in blaming world leaders, cause they're supposed to be the people who look out for the best interests of the people, and they're failing at it.
  • The "Fuck You, Greta" Movement
    Greta Thunberg is essentially akin to a fundamentalist, she only sees this one problem (that of climate change) and doesn't have the knowledge nor life-experience to be able to properly assess the complexity of the policy question.

    The fact that someone has it right on the first question doesn't mean their opinion is worth anything on the second question.
    ChatteringMonkey

    I don't think Thunberg is trying to be an expert at all on the subject if her message is simply to "listen to the scientists". So much as she's asking people to listen to her, it's to take the actual experts on the matter seriously, people who are older, have degrees, and a lifetime of experience studying the issue.

    It would be fantastic if we can all agree that climate change is happening, urgent action needs to be done, and we simply disagree as to the specifics of what approach to take. However, as seen in the recent COP25 our world leaders are not even at that stage yet and that's the problem.
  • The "Fuck You, Greta" Movement
    So, if I felt Greta's words deserved a hearty "fuck off" had they been spoken by an old shrew, she gets it too.Hanover

    Well, if Greta's message were spoken by an old shrew, would there have been the same negative backlash from people on the other side? To be honest I'm not really sure. The situation really reminds me of the bashing of AOC by the right back when she became relevant.
  • Is time travel possible if the A theory of time is correct?
    The idea of time travel is that someone (or something) is moving in time (at a different than normal rate), while everyone and everything else goes on as if nothing happened.SophistiCat

    If that is the case, then the standard conception of backwards time travel of simply going back to the past is strictly impossible, because your actions from there on out will inevitably affect the present, and everything from the time you have left will not go on "as if nothing happened".

    However, I don't think there is any specific definition of what time travel is, apart it being some mechanism that can get you to a world which is in "2000 AD". There are many different ways which one can conceivably do just that in fiction, some of which involve divergence (like multiverse theory) and others which don't (like simply rewinding the universe).
  • Is time travel possible if the A theory of time is correct?
    Suppose that the metaphysics behind the A theory of time is correct, is it possible to travel to the year 2024 (or the "future") or the year 2000 (or the "past") or does time travel require the B theory of time to be correct?Walter Pound

    Travel to 2024 is simple. Just wait 5 years or less and the passage of time will take you there. Of course, it's past travel is where things get tricky. If one assumes presentism, then there is no time that exists apart from the one that we are in in 2019. Because there exists no year 2000 destination to travel to, then it's impossible to really "travel" to 2000 like you would "travel" to France for vacation. But that doesn't mean you can't create your destination. Just think of the universe as if it were a movie playing on a VHS, and hit the rewind button. Give it 19 years and soon you'll find youself in the year 2000. Simple as that. No extra times or 3D universes required and everything is kept in the present.
  • B theory of time and free will vs determinism debate
    Best I can explain the general stance is that eternalism gives equal ontological status to all events. What that status is isn't necessarily part of the view. My opinion on that is certainly not typical of eternalists.noAxioms

    Suppose I am an ontological nihilist who believes that nothing exists, including events. In that sense, all events have the same ontological status, that of not existing. Would that count as "eternalism" then under your view?
  • B theory of time and free will vs determinism debate
    I thought I was pretty explicit in my comment there, so you either have no understanding, or you refuse to accept the way I am using the word.noAxioms

    Of course I have no understanding of the way you are using the word, and I have tried to make it explicit why in my analysis, which you have declined to comment on. If you have a disagreement with the way I have analyzed your definition, then please point out where that disagreement is.

    The reason why I have been using "currently" is because that is the only way I can make sense of your claims, but I very much welcome an alternative conception, so long as it makes sense. Indeed, that is the very reason why I am having this discussion with you.

    I have given some points where we may differ and what I find lacking in each of them but if you don't want to engage with them, then I would assume that either you don't have an actual response, in which I suggest you reevaluate your views, or you're just not willing to respond for whatever reason.

    So you're not trying to drive it to self-inconsistency, but merely decline to accept it, which is fine.noAxioms

    It's neither. Like I just said, it's that I don't understand it. My acceptance of eternalism isn't really relevant here since my main goal is to try to understand what "tenseless existence" amounts to.

    And again I must add that this isn't really just a problem exclusive to me. There is actually an entire debate centered around what eternalism even means, and I think it's this idea that there is some form of non-temporal existence that leads people to draw mistaken or confused ideas about these views about time, which includes questioning whether the eternalism vs. presentism debate is merely semantical, which it obviously isn't. I would suggest you look at the link I gave you earlier to the triviality problem, but if you don't know where that is, then here's the link again here. If you don't want to respond to my points, then feel free to respond to theirs. Or not, it's up to you.

    I'm asking you to explain it for me since that's much more faster than asking me to read a 42 page paper. I assume you read the link yourself.

    No one is claiming that space flows. If they did, then you can rest assured that that flow would need to be with respect to something.Inis

    Of course no one isn't. All physical objects exist in a backdrop, called space. What backdrop does space exist in? Perhaps we need a hyperspace to contain space. But what backdrop does hyperspace exist in? And so on and so forth.

    That everything at all times exists (some say exists "simpliciter"); i.e. the block universe theory.Luke

    And what does "exists simpliciter" mean here? This is just replacing one word with another. It could mean "existed, exists, or will exist", but that doesn't really get us anywhere new. Don't know what else it could possibly mean though so if you have something then now is a good a time as any.
  • B theory of time and free will vs determinism debate
    Couldn't it equally be said that the tensed version of existence is reducible to the tenseless version?Luke

    What is the tenseless version of existence then? That is what I am trying to get at here. I have no clue what the notion of saying something exists means other than saying that it either was, is, or will be.

    Presentism is the view that only present objects exist.A Defense of Presentism, Ned Markosian

    Some people would suggest that that definition is trivial. "Of course everything that exists is present, that is what 'exists' means!", they'd claim, and in a sense they'd be right. I believe that in all views about time wouldn't disagree with the notion that what exists is present at heart, but where they differ is in really the extent of what exists (that and whether there is this thing called the passage of time). Markosian brings up the idea of listing "existing" things, which is a good place to start. The presentist's list would be much smaller than the growing block theorists, and the growing block theorist's list would be smaller than the eternalist.

    If time flows, as A-theory claims, what does it flow with respect to?Inis

    This is like asking "what contains space?". It's a confused question that I think is based upon the mistake of treating the background as part of the foreground. Space and time are the setting for objects to exist and events to take place, but they are not objects and events themselves.
  • B theory of time and free will vs determinism debate
    The fact that 'exist' appears on both sides. 'Exist' means 'presently existing'. 'Hot' means has a hot temperature. Those are useless circular definitions.noAxioms

    Fine then I can substitute those terms with "is", "was" and "will be". Doesn't really change my point that those are the only senses in which I can understand something existing. There shouldn't be any problem in understanding what they mean which was what I am concerned about here.

    If I say a T-Rex exists, I mean it is a member of the set of objects contained in the universe. I don't mean it is a member of the set of objects currently contained in the universe.noAxioms

    I still do not see how you're using the term "is" in a manner that isn't present tensed though. Also what exactly is in the "set of objects contained in the universe"? I assume that it is going to contain the set of objects that are currently contained in the universe. In addition, I imagine that you're also going to say that the set of objects contained in the universe also includes the set of objects that once existed in the universe, of which your T-Rex is a member of. Finally, you will probably also say that it includes the set of objects that will be contained in the universe as well, so as to include things like the 2024 Olympic Stadium, which you will say "exist" as well under the B-theory.

    The problem as I see it, though, is that these are the only sets that I can think of. I do not know of any other sets that could or should be included in your set and from my point of view, those three sets mentioned above are exhaustive. And if these three sets are all that exhaust what you mean by the "set of objects contained in the universe" then to say that something "exists" under your use of the term is just another way of saying that it either "was, is, or will be", all of which are temporal forms of existence. So this doesn't really offer up a new form of existence at all, one that isn't reducible to a tensed version of existence.

    Of course, you may want to say that there are actually other sets that could be included in the "set of objects contained in the universe", but this just leads us back to the original problem. Just like you want to find a fourth sense of "existence" you need to find a set of existing objects that is distinct from the ones that I've just described.

  • B theory of time and free will vs determinism debate
    But as for the run of the mill B-theorist, they'd not ever say that the universe exists now, or it once existed, or will exist.noAxioms

    I'd imagine that alot of them would try to say that, but that leads to an incoherent view which in turn leads to confusion and mistakes. Confusion to the point where people even question whether or not there is an actual disagreement between the A and B-theories of time. And when you have people questioning the substance of a core issue in a field of philosophy, you know that something's gone wrong.

    I think a lot of people see the universe as an object like that, coming into being somehow from non-being, just like every actual object in the universe. I don't. I think it contradicts what a universe should be.noAxioms

    I don't think a creation event or beginning to time exists either, but that is irrelevant to the B-theory or the A-theory since an eternal universe is compatible with both.

    Are you saying you don't understand the view or you simply disagree with it? It's hard to tell from you posts.noAxioms

    I have an understanding of the B-theory and the A-theory of time which I believe captures the essence what most people understand the view to be. That version of the B-theory I also happen to disagree with but that is not something I will go into here.

    The problem that I have is how A-theorists and B-theorists describe their views, which I honestly find baffling given how confusing it can be. I feel like the reason why some people (don't know if Terrapin Station is a part of that group) say that the B-theory is nonsensical is because they hear phrases such as "all times exist, but by 'exist' I don't mean it in the way we traditionally mean it". Well what does it even mean then? Given the lack of a satisfactory response on some fourth "tenseless" version of existence, then one may conclude that the view makes no sense at all.

    You seem to want a different word since you disapprove of it being said that those events 'exist' in the same way that I exist. Then I would still balk at that same word being used to say that the universe exists, since it doesn't seem to be an event or a created object or anything.noAxioms

    It's not that I disapprove of the word being used. I gave a number of different ideas of what the B-theorist idea of "all times exist" could mean, and all of them are A-series terms, which you have denied. My question is what other meaning of "exists" could there be if it doesn't refer to "presently existing", "did exist" or "will exist". Feel free to use the term, but just be clear on what it means.
  • B theory of time and free will vs determinism debate
    There is no 'the present' or 'now' in the view, so I'm not sure what is being referred to with that comment.noAxioms

    What I am saying is that first part of your sentence, that there is no "present" or "now" doesn't make sense. There is no meaning to the idea that the "block universe exists" without stating that it either exists now, did exist, or will exist.

    We cannot eliminate the present from our discussion, especially if we are talking about what exists (which is by the way, a present tense term). Just look at our conversation right now, for instance which is embedded in the now.

    As a result, I believe that all views about time are "presentist" to the extent that everything that is said to "exist" is presently existing. It is sort of trivial, but that is what "exists" technically means (as again, it is a present tense term). Of course, this is not to say that we cannot distinguish the views about time in a substantive way, as I do believe that there is a deep disagreement between them, but such a difference shouldn't be based upon a rejection of the above statement.
  • B theory of time and free will vs determinism debate
    A-series terms which leads to nonsense when discussing a B-series view. So "could have done otherwise" is an example of an A version of the definition.noAxioms

    Well, what sort of non A-series terms are there? I actually think the attempt to remove A-series terms from a description of the B-series is what leads to nonsense (such as this whole "triviality problem" that people are currently discussing about the A vs. B theories of time). Just take what you said later as an example:

    The block view just is (my emphasis).noAxioms

    What could the "is" mean other than that it is present, or that it exists now (both being A-series terms)? Of course, I imagine you don't want to say that you mean that by your use of the term, but what else could it possibly be? A tenseless use of the term? What could that possibly mean?

    Now as for my own views on the matter, I think that the B-theory of time does make alot of A-series terms irrelevant, but does not eliminate them altogether. The idea that things "will happen" or "did happen" make no sense in a world where time doesn't pass.
  • Arguments for discrete time
    Problem is that means a second and a year would have the same information content which does not seem right. Clearly more information in a year - the continuum seems paradoxical. Maybe it's one of those concepts that we can conceive of in our minds but never occurs in reality? Reality seems deeply logical and free of paradoxes.Devans99

    Thing is, you're arguing against the opposite of my position. I never advocated for the point continuum where everything is made up of an infinite number of points (which would lead to your criticism), but instead a gunky continuum that doesn't contain any such fundamental units at all. Personally, I find the point continuum to be a useful tool that doesn't describe reality, but that does not mean I take reality to be discrete, which is a concept I also consider to be problematic in other ways.
  • Arguments for discrete time
    What structure does time have if it's not a series of instants?Devans99

    Just a series of events without any smallest units. Similarly space without points would simply be space without any fundamental composition. There is no need for time to be a series of instants or fundamental units any more than there is a need for space to be composed of fundamental units or points.

    But if an event has no duration it would not exist. 'Now' could not exist if it had zero duration. Think about filming someone for zero seconds - you'd have no film right?Devans99

    I never said that there are events that are instantaneous nor that time is composed of them. Quite the opposite really.
  • Arguments for discrete time
    I have a couple of arguments for time being discrete rather than continuous (actually similar arguments can be used for discrete space too). Thanks in advance for any feedback.

    1. A point in space cannot have size=0 because it would only exist in our minds and not reality (no width; insubstantial)
    2. Similarly, the point in time ’now’ cannot have length=0 (if it exists for 0 seconds, it does not exist)
    3. Or if a ‘now’ had length=0, then a second would contain 1/0=UNDEFINED ‘nows’
    4. So ‘now’ has length >0
    5. Can’t be length = 1/∞ because ∞ does not exist (∞ + 1 > ∞ making a nonsense of ∞. Or if you define ∞ + 1 = ∞, implies 1 = 0)
    6. So a ‘now’ has a finite, non-zero length. Time is composed of a chain of ’nows’ so time must be discrete

    Or

    a) Imagine a second and a year
    b) By the definition of continuous, both time period are graduated identically (to infinite precision).
    c) So there must be the same information content in both (same number of time frames: ∞)
    d) But a year should contain more information than a second
    e) Reductio ad absurdum, time must be discrete

    Who says the temporal continuum needs to contain instants? Likewise who says that the spatial continuum needs to be pointy? Perhaps the continuum has no fundamental level at all, no unit with which all other quantities are multiples of.

    If that is the case, then the idea of "now" as a snapshot moment in time is mistaken and the passage of time as a succession of said moments (not unlike a succession of strips on a piece of film) is also confused. This is what you seem to implicitly assume in the your argument. Just as objects may be distant from one another without any fundamental length, events simply come and go continuously without any fundamental duration.
  • Time and the law of contradiction
    It's continuous, as opposed to discrete? "Gunky" seems to imply a mixture of both.Metaphysician Undercover

    I don't define the terms. I would've liked to refer to it as continuous, but there are also continuums that contain fundamental units in the form of dimensionless points/instants which should be contrasted with that of gunk.

    In any case, this discussion is getting off-topic.
