What exactly constitutes the size of the universe? Does the empty space outside the farthest rock or particle or whatever of our universe count? I think it's a loop of some kind. Like you could travel straight forever but still not leave because of how it may be shaped.
No, there's a border out there somewhere. Eventually, it will collapse back in on itself, and the cycle begins anew.JustPlainLucas
Actually, the guys that won this year's Nobel prize in physics figured out that the universe's expansion is actually accelerating, which suggests at some point everything in the universe will be so far apart all energy will dissipate and the universe will freeze and "die". And that'll be the end of it.

At least that's what I heard. :P
I hope I'm dead before that happens. :o
Oh don't worry, I've got it on good authority you will be. ;)

I really don't think there's enough evidence to say one way or another. But, the big bang theory has explained and even predicted many phenomena we see in the universe, for example, the cosmic background radiation. And if this reality did begin in a bang or sorts, than I'd think that would imply a starting point of expansion... and from that, a cosmic horizon. And this is actually what we kinda see when we pear back in time to over 13 billion years ago, we see what the beginnings of our universe looked like... and nothing after that. Now this doesn't imply a horizon must exist, just that the light from anything beyond what we see now hasn't reached us yet.
But whatever, my answer would not be indifferent, but... I don't know, ask me again when the information comes in.
Nothingness is infinite, but I don't think anything else is.

wow deep. Really that's an interesting point. It is interesting, and I have considered that also. We tend to think of the universe's infinity as infinite planets and stars and all that siht. But what if that ends and It's just eternal nothing. That seems very logical actually.

I think there is "something" and a "negative something" because opposition seems like a theme of the universe. idk :?

That seems very logical actually. Why does that seem very logical?Because the if It's nothing then it can just keep going cant it? You don't need to think about where it ends because it doesn't. Whereas if you think of the universe having stuff like planets and whatnot occupying the space thoroughly then all you can think is "If It's infinite then where does all the stuff occupying it end, how much is there, can it really be infinite physically?" That's where the idea that all the stuff just ends somewhere and that could be thought of as the border of the universe. It might not be some sort of perfect circle with the contents of the universe inside it; Some things may reach further out into the nothing than others. But if there's a point where stuff just doesn't exist then it doesn't need to end. I'm not sure how much sense I'm making or how well I'm expressing my theory. Do you get what I'm saying?

As much as I would like to agree, the origins of the universe are speculation at best and wild guesses at worst. I believe that is of the utmost importance when theorizing about the "final fate" of the universe, if there is such a thing.
The universe cannot be infinitely big. If Universe is infinitely big then quantum fluctuations would have created the Earth and everything in it infinitely many times and we would not have evolved.
Wow... that's so wrong it hurts. No... the universe could very well be infinite, with an infinite number of Earths in this exact configuration. You were halfway there, then you were confused by the notion of quantum fluctuations in the Inflation field, then... bam... off the rails.
It's hard to imagine it not being infinite. If you get to the end, what's beyond that?

It's easier to imagine an infinite expanse, or an end past which there's nothingness? I think you'll find that they're both equally incomprehensible; fortunately our ability to imagine these things has no bearing on reality. Go Math and Physics!
