Please correct me if I'm wrong, as I know little about this subject and am mostly hypothesising:
The universe expands at the speed of light, right? Recent research has shown that over billions of years the speed of light has been gradually falling. Does this represent the declining rate of expansion of the universe? When the universe stops expanding, the speed of light has reached 0, and everything stops, temperature reaches absolute zero and time has no meaning. Unless, of course, gravity pulls everything back together, and the universe contracts at the speed of light, which gradually speeds up. This would mean that time would reverse, right? Wouldn't it be weird living in a world where time flows in reverse? Would we even notice it? You'd be born out of a coffin and die in a womb. Creepy.
Then there's always The Paradox. If you bo back in time, would you already have done it as it's already past or would you be crafting a new past, if so, where would the old past where you travelled from go to and would your memories be altered, which could alter them to force you into not making the time-trip and thus erasing the past?
which is where idea of multiplie universes comes in, when you go back in time, and change something, even just by being there, a new universe is started from that point, independant of the one you left. or something along those lines

]]>So what would happen if there be some "law of thermodynamics", but one that applies to both physical and metaphysical?
Perhaps you'll find this page interesting.
]]>As for traveling backwards in time, our current knowledge says that it is we don't know how to do it. Not that it is impossible Big difference.
To the argument that there would be time machines everywhere, it may be that time travel as such is possible, but humans were destroyed before making that discovery. Or that we were moral enough to not use it. Or that it is possible and they do travel, but they do so in ways to go undetected by us.
]]>Scientists are saying that it's theoretically possible to travel into the future by going through a wormhole, and to travel back to the time you came from by going through it the other way, but it's not possible to travel back in time unless you travelled forward first. If it was, we'd be seeing time machines from the future all over the place.
]]>On the other hand, returning to thermodynamics, it could be possible that in half a trillion of years we realize that it is possible to travel back in time, and go to a "nice" time.
]]>Second, is that you are asking for mathimatical proof for something that is not math.
]]>And anyway, the law of thermodinamics doesn't apply to ideal objects... would you apply thermodinamics to numbers, to family relations, to feelings, etc?
Would said objects really "exist" if we didn't?
Maybe yes, maybe not, how could we proof a solution for that?
And I believe you misread my first post. Thermodynamics is the reason why the energy in any proper subset of the universe would approach 0.
Well, I just wanted to keep my question. You are sending my question a trillion of years in the future, and I can't wait so much to know what would happen if in a near time someone proofs (not only thinks that there could be a solution like thermodynamics) that birth and death of everything is based on logic?
