I guess a more pertinent question would be - WILL time end? According to basic logic and most Einsteinian scientists, with the ever increasing rate of our universe's expansion, the universe should eventually cool to absolute zero, thus no motion, thus no energy, thus no time. However, modern theories tend to insist that the universe could theoretically go on forever. Most modern physicists agree that we do live in a zero energy universe, after all, and that fact alone confuses the fuck out of me. If we have zero energy total in our universe, how is it expanding? Wouldn't gravity and expansion cancel each other out?
I still don't have a strong grasp on quantum physics or string theory, so I can't comment too much on those, but my more knowledgeable friends seem to insist that our universe could go on forever in cycles of birth and death, and that other universes could collide with ours creating another big bang.
Time is weird. I once had a professor tell me that gravity was a force from the past, and that expansion is a force from the future. If gravity's force ever exceeds expansion's, we would start to travel back in time until the universe collapsed on itself. It's anyone's guess what that might lead to. Anyone know if this is true?
