There is extensive debate and literature about the nature of spacetime and whether it is a substance or not. Perhaps you enjoy this. — MoK

One view is that spacetime is a substance: a thing that exists independently of the processes occurring within it. This is spacetime substantivalism. The hole argument seeks to show that this viewpoint leads to unpalatable conclusions in a large class of spacetime theories. — The article you provided a llnk to:

Oh dear.

I studied this article a long time ago and had a hard time grasping all its content. — MoK

Yes, I can imagine.

None of this is new to me, but you have still failed to provide a link to backup your claim that spacetime is a substance. That is what I would like a link to.

Spacetime is a substance and has a curvature around massive objects. Spacetime can affect the motion of any other objects so in this sense it exists and has a property, its curvature. — MoK

Please provide a link to this information. As far as I know it is nothing but a concept used to refer to points in time in space. But I an interested in viewing anything you have to further my knowledge.

I defined time to a good extent in the previous comment. Please let me know if you need elaboration. — MoK

No, you said time is a substance. you were asked you to explain how you reached that conclusion.

Time is defined as the fourth coordinate that is required (along with three spatial dimensions) to specify a physical event.
Time if anything is a human construct used to understand the passage of events.

What I do not understand is the jar of strawberry jam in the first image.

I don't understand what you are trying to say here. I also don't understand the implication of this to the first premise as well.

P1) Time is needed for any change
— MoK

Time is not defined in the OP. It could be referring to anything.

Cool, so you agree with the second premise.

P2) Nothing to something is a change
— MoK

More or less, if you are saying what I thought you were saying.

Time is a substance that allows change. Therefore, this premise is also correct given the definition of time and nothing.

P3) There is no time in nothing — MoK

As I said, you gave no definition for time. But to claim that time is a substance would mean that it has some sort of physical presence, which is a long stretch of the imagination. Could you maybe explain that a bit better.

P1. Inside the cubic volume A there is a complete vacuum.
P2. Objects need material to exists
P3. There is no material in a A
C. Therefore something cannot come from nothing. — Sir2u

I cannot understand how your conclusion follows from the premises. — MoK

My apologies,you are right there is a bit missing.

C. Therefore something cannot come from nothing in cubic volume A.

It looks pretty clean to me, maybe the only do it figuratively.



But it appears that they still leave love letters to them.

It must be true, I found it on the internet. :rofl:

No need to explain this one.

P1) Time is needed for any change — MoK

Time could be a trillionth of a second or even less, lots can happen in that time and we would not see it happen.

P2) Nothing to something is a change — MoK

If you mean that something existing where nothing existed before, then you might be right. A tree in your garden where there was none when you moved in 25 years ago does not mean that it came from nothing.
The idea that the universe came from nothing is in my opinion an unfounded statement, because they have no idea what exactly was there before. If the big bang theory is correct then there was something there before.

P3) There is no time in nothing — MoK

Time is attached to action, not objects.

C) Therefore, nothing to something is logically impossible. (From P1-P3) — MoK

Yes maybe so, but not using your syllogism. Try this.

P1. Inside the cubic volume A there is a complete vacuum.
P2. Objects need material to exists
P3. There is no material in a A
C. Therefore something cannot come from nothing.

I have multiple questions that need answering. — an-salad

Did you try google?

First, if there are infinite whole numbers, and there are infinite decimals between 0 and 1, and there are infinite decimals between 0.1 and 0.12, does that mean that infinity itself is infinitely infinite infinitely (etc.) ? — an-salad

There maybe an infinite number of answers to this question, but I don't know any of them.

Also, will there be a manned mission to m87 by 2030? What if u brought a talisman from Cambodia? — an-salad

I just asked NASA, they said no. They might get to Mars by then but it will be a couple of hundred years before they attempt any kind of inter-galactic flights. And as far as they are concerned they don't give a damn where you buy your talisman from.

Also, Ive never left Chicago in my life. How is it different out there? Is the sky purple? Are there dinosaurs? Are there three large moons? — an-salad

What do you mean by "out there"? We sometimes have almost purple sky, there are iguanas that get pretty big but we only have three moons after the second or third six pack.

Also he's at a podium so I assumed he was a teacher. Possibly an English professor. — TiredThinker

I assumed he was the preacher at a southern baptist church, and from what I remember some of them do need to be more pacific.

Yep that is a good definition, stupid people fail to use the intelligence and education they were given, regardless of the level they are at.

But the blame for stupidity cannot be laid upon the educational systems, when they fail to do their job properly the product is ignorant people.
Stupidity is a personal choice or habit disease picked up from other stupid members of society.

Point was more that if four people are interested, and 25 are not, perhaps 'the forum has spoken' and we must remain but abstract avatars to one another :) That said, I'm happy to just take the four and have the damn conference - if that's what you're getting at :) — AmadeusD

I am not sorry to say that I don't give a shit about the naysayers. If it is something that will not have any affect on them why should they waste their time trying to stop others doing it?

If they are not interested, they can either just ignore it or be polite and say no thanks.

Let us know the setup and I will see what I can do to join in.

Men are born ignorant, not stupid. They are made stupid by education.

— BR — Mikie

That would depend on the definition of stupid would it not.

According to some dictionaries:
Stupid, adj

• Lacking or marked by lack of intellectual acuity
• Lacking intelligence
• In a state of mental numbness especially as resulting from shock
• Devoid of good sense or judgment

Would you like to have The Philosophy Forum AVL conference? — AmadeusD

It might be an interesting thing to do, getting to talk to people from around the world face to face.

I think your mistake here was including the option for NO in the poll. If they are not interested why should they be allowed a say in the activities.

Basically a guy literally becoming more pacific-like when someone asks them to be more "pacific" as opposed to more "specific" which was likely what they meant. Is this racist? — TiredThinker

Or maybe he is just an angry guy and they were making fun of that.

Being as the joke itself has nothing to do with the color of the person it is aimed at, there can be no valid screams of racism. The truth is probably that someone in the congregation took the picture and did the art work, one of his brothers.

Do you know more tricks? — javi2541997

:cry: Nope

So cool, why Honduras if you don't mind me asking? How does it differ from, say, Guatemala or Costa Rica? — Lionino

My father was a captain on a ship that ran between New Orleans and several other parts of the gulf coast to Honduras and other parts of Central America.
When I was a teenager I used to travel a lot with him and just loved this place. Later he moved down here and I followed a few years later.

Guatemala is a nice place, but back in the 60's and 70's it was not really pro British. They had a claim against England that British Honduras was theirs. It later became Belize and independent.

I know I do many weird things... — javi2541997

You have no idea how alike we are then. :wink:

Try this:
find any topic in Wikipedia, in English.
In the main article, click on the first link that is not Italic.
Do the same on the next articles.
By the time you have reached the seventh or eighth article you should be looking at something to do with philosophy.
It does not work for everything but it should for about 90%.

Supratrochelar. — javi2541997

Please explain your reasoning, under what circumstances, reasons, warped thinking does this qualify as a last word.

That is only about instantaneous speed. — Lionino

If the wheel has a circumference of 2 meters, the car will advance 2 meters for each rotation if there is no slippage. That is the rotational speed of the wheel in relation to linear velocity of the car. No part of the wheel can advance fast than the car. in fact at certain parts of the revolution all points around the circumference are traveling in the opposite direction to the car. Combining the speeds is not possible because they do not have the same vector.

Nothing you wrote in any way explains how any part of a wheel can travel faster than another part of it, which is what I asked you to explain.

If you are considering linear speed, yes. If you are considering instantaneous speed in relation to the floor. — Lionino

I was just stating that I can find no way to explain how it would be possible for one point on the wheel's circumference to to be traveling at a different speed to another point on the circumference. That just cannot happen.

At the same instance that the patch is in contact with the road the top part of the wheel also has a velocity of zero as does every equivalent area on the wheel.

Not only is there speed that comes from the cars movement, but from the tire going around itself. — Lionino

But we can always add to that the speed of rotation of the earth, the speed of orbit of the earth, the speed of the sun orbiting the Milky Way.
But that goes way beyond the point de Grasse is trying to make.

Now, which part of the wheel is moving twice the speed? I guess that would be the top of wheel. — Lionino

Nope, that would be science fiction, the part at the top travels at the same speed.

The problem here I think is one of "in relation to what is the velocity measured".

Lets try looking at this from a slightly different point of view.

You are walking or running down the road at a certain speed. each time your foot touches the road it stays there for a certain time while the rest of your body moves forward.

From this point of view, de Grasse is correct. In that instant your point of contact with the road is not moving hence a velocity of zero.

Have you met the devil yet? :wink:

I was born in England, lived in Canada, USA, Belize and have lived in Honduras since '75.

So the best thing to do here would be to post some question about things you wish to know and wait and see if anyone has answers.

I doubt anyone here would call you a racist for asking questions.

There are hundreds of different news providers online, spending some time reviewing them would help to get a better understanding of what is going on around the world. If several groups say the same thing and there is no one screaming "lies", then there is a good chance it is true.

I think so. What does Destee mean? — TiredThinker

Not trying to be nasty, but your name suits you well.

Is there any specific topic you would like to discuss? From my point of view looking for a dedicated forum would allow little or no discussion because they would mostly be of the same mind. Where as here there are many countries, ethnic groups and points of view to provide a better gamma of views.

no I don't think that I learned anything. — Massimo

Will you be going out like that again soon? Will you apply for another job?

My night sucked and I don't know what any of these experiences mean if They mean anything. — Massimo

They will only have meaning if you give them meaning, did you learn anything from them?

Thanks

I have a few panel installed, started mostly as backup because we had a lot of outages and I was working online from home. But I put a few more up and now I can run the refrigerator which is the biggest part of the bill. I also have a 12volt light system so I always have light.

I am hoping to have all of the major work done in the next year or so, that will leave me with just maintenance and damage costs for the future. Fingers crossed on that one. :lol:

Maybe the question would be better suited to a place where more people with specialized American knowledge.
The international and more intellectual nature of this forum does not enhance your chances of getting answers to questions of that type.

I'm sorry to hear about your setbacks. Money's always a major obstacle, isn't it?
Maybe you're up to some less physically demanding tasks this year. Tiling isn't too hard... just ridiculously difficult sometimes. Painting a roof sounds like a bigger job than I'd ever take on! I can just about manage three rungs of the ladder to wash the top windows. — Vera Mont

Thank you. I am just short of 70, if I leave things much longer I will not want to do the the work at all. I plan on retiring in the next couple of years and need to spend the money to do the work while I still have some coming in.

I feel so unaccomplished reading this. I've always wanted to build a whole house, — L'éléphant

I have designed and built three, mostly with just help for the heavy or excessive time consuming stuff that I could not get done inside the time frame by myself.

The house I have now was originally a wooden framed building that I built. I renovated it by changing the framework to metal. I was lucky that I did because we had a bad earthquake,7.2, and it came down from its original 2 meters in the air to sitting on the ground on 2 sides. I was able to lift back to one meter and all of the damage it received was in the siding panels and a couple of minor bends in the frame.

Does anyone have a winter project they would like to brag or complain about? — Vera Mont

We don't really have a cold season down here, it is more of a dust and mud type of thing. And the temperature rarely gets too low that you need more than a sweater or a light jacket .
The list I have is too big to mention all of it, I will just list the larger ones.

Finish building fence.
Paint roof and rest of outside walls
Replace ceiling in main bedroom.
Finish tiling and plumbing in new bathroom

Some of these were started before the covid lock-down and could not be finished, then last year I had an accident and have not completely recovered still. There are about another dozen things on the list, but money and time will keep them from being done before next year.
