If time is infinite, — Devans99
For the theorem to apply, the system must have constant volume. That rules out infinite universes and finite universes with changing volumes, which are the only types predicted by current cosmological theories.If time is infinite, the universe should go through all possible states eventually. — Devans99
If time is infinite, the universe should go through all possible states eventually — Devans99
If time is infinite, the universe should go through all possible states eventually. A similar idea to this is Poincaré recurrence theorem: — Devans99

So I ask again. What is your understanding/definition of time? — tim wood
If the video was not complete, how would you play it? — Shamshir
We don't actually need to know what time is in order to work out it has a start, — Devans99
I suppose if it has a start, then events can be ordered temporally, yes? But relativity says, for a broad class of events, that they cannot be absolutely so ordered. — tim wood
But the real question is that at there are times and places where time simply appears to be not well-defined, and the same with "places." — tim wood
You wrote, that 'something 'other' than only now exists'.
But if I told you that there is only now and now is eternal, to reconcile the two, would you believe me?
Now, you might ask, but if now came from nothing - nothing predates now, does it not?
It does not. There is no is, do, or be with nothing. Only nothing.
If nothing is, it is not nothing. — Shamshir
So, does it have an end? It does. — Shamshir
I will try to explain.Not sure I entirely follow, I think eternalism maybe correct (past, present, future all exist). 'Now' cannot exist eternally - if it did, the things within the universe (particles etc...) would have no temporal start and without a temporal start they could have no existence. — Devans99
As long as the start of time precedes all other events in all reference frames, there is not a problem? — Devans99
I'm sure Hawking has been mentioned in your threads. He opined that time is akin to the surface of a sphere in that it is boundless, yet has no beginning or end. — tim wood
Democritus, for example, may have given us "atoms," but he couldn't manage, or even imagine, nuclear physics and sub-atomic particles, and that because he was looking in the wrong place (among a lot of other reasons). — tim wood
Let's try this. If something has a start, then there is either something or nothing prior to it. — tim wood
1. Can’t get something from nothing — Devans99
2. So something must have existed ‘always’.
4. It’s not possible to exist permanently in time (an infinite regress; it would have no start so could not be), so the ‘something’ must be a timeless first cause. — Devans99
Modern physic says not only that you can, but that we have, and do — tim wood
A timeless something is incoherent. Make it coherent. — tim wood
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
