Is there a theory that says that eventually the universe will expand so large that it will collapse in on itself and create another big bang?

What are your thoughts on the fate of the universe?

"The Last Question" by Isaac Asimov is a short story about the fate of mankind and the universe. Idk if everyone on this has read it or not, but I love it. Here's the link: http://www.multivax.com/last_question.html

You're thinking of the Big Crunch.

The Big Crunch doesn't necessarily mean another Big Bang though.
Look for the the Big Bounce, or the Cyclic model, OP.

the oscillating universe theory, where the universe infinitely cycles between big bangs and crunches, makes the most sense to me. ill just believe that until something else is proven. i dont buy the idea of a big freeze

Yeah. Except time itself originated with the big bang, and it ends with the big freeze. How you gonna escape that?

there is no big freeze. there is an infinite cycle of big bangs and big crunches. time is infinite.

How would you know that? Evidence we have now points to the opposite, we see distant galaxies accelerating away from us, and they're accelerating at a greater and greater rate as time passes. There's not enough gravitational force, even accounting for dark matter, for a big crunch to occur.

This is my understanding of the topic, anyway.

there is a presumption that magical dark energy is causing the universe to expand at an accelerating rate yet every experiment performed looking to confirm the existence of dark energy or even dark matter has come up empty handed. thus the cyclical model is supported by an equal amount of evidence. the whole "red-blue" shifted model is in serious question at this point

None of that justifies a big crunch model. If we're gonna posit something based on lack of evidence, I'd rather go with space fairies. They're cute.

Well I'm not going to make an argument for the Big Crunch because I don't think it will happen, it's Big Freezes all the way down. However, I would make an argument for their nonetheless being an infinite number of Big Bangs, and thus the universe having a cyclic quality without any need for a Big Crunch.

The argument for this is simple, one based on a priori logic rather than a posteriori empiricism, as well as the Copernican principle: our universe, apparently, arose from nothing at all into the universe we perceive today. If we believe in the Big Bang, we must minimally accept this. We must take nothing to mean really nothing, as extension in no qualities of any kind. In this way the moment immediately after the Big Freeze is the same as the moment before the Big Bang -- time ceases to exist for an infinite amount of non-time, because what time is is a measurement of change, and in nothing, there is no change at all.

Because we know it is possible for the universe to arise from nothing, and know it is going back into nothing, and we know that nothingness can exist for an infinite amount of time, it would be a violation of the Copernican principle to assume that our vantage point is the only time ever that nothingness would generate a universe. No, that would imply a violation of causality and us having a privileged perspective, so we must reject it.

If nothing really is nothing, and the universe can come from nothing but also inevitably goes into nothing, then there's nothing about nothing that can stop universes from infinitely eternally being formed out of it. Since there are an infinite number of universes, there will also be an infinite number of identical universes, eventually. Thus, cyclical universe.
