Hm, it is quite an interesting topic. If universe is expanding, then what was in the space, where universe hadn't yet expanded, before it expanded there.

Like at the expense of what does it expand? (I think it is hard to give certain answers to such questions but everyone can give their opinion/speculate.)

i'd say nothing. scientists still haven't figured out all aspects of the big bang, let alone what (if anything) existed before it. actually, we'll probably never know.

and as far as expansion, there aren't opinions or speculations, it's been proven that the universe IS expanding. it has been since the big bang (extremely slowly), and it'll keep expanding until it either bumps into something else, or reverses through the big bump, then crunch. at that point the universe will revert back to what it was before the big bang.

Ok, by speculation I didn't mean expansion itself but what lies beyond universe. I think it is hard to say for certain.

i really think theres no end to universe just like the concept of infinite with numbers. i mean i dont understant how it couldnt be, is there supposed to be like a brick wall at the end of it?

Not necessarily a brick wall. Earth might also seem infinite to someone who doesn't know that it is round. Maybe universe bends into some kind of circle of something so you'll eventually arrive at the place you started of if you move forward all the time.

Now I'm not saying it is like that, and if I had to take a guess I would say its infinite too but it was just an example.

Also it has been mentioned in the thread that it is proven that universe is infinite, although I haven't researched the matter myself.

im no scientist but that theory does not make any sense. universe is not like earth at all

no

it does make a sense...but you have to understand a lot of physics (and especially quantum physics) to be able to decipher "how it works exactly"

btw.: you know "Klein bottle" or "Möbius strip"?

@pinusar: it wasn't me that said the universe was proven to be infinite. it very well may end at some point, although i doubt it. now SPACE, on the other hand, has to be infinite. yes, our universe may come to an end (size-wise), but that doesn't mean it ends because it had reached the end of space. if anything, it will bump into ANOTHER universe, causing a crunch in mass expansion. if there is a point in space where no universe exists that doesn't mean it isn't there. it simply continues on as a pitch-black nothingness.

here's how i look at it: our solar system is so large, yet it doesn't even take up a fraction of our observable universe. the universe we exist in hasn't even been fully discovered or examined yet. if it's THAT large, it has to exist as something that isn't even a fraction of ALL of space.

i DID say it's almost been proven that there are multiple universes, so that's where you may have misinterpreted what i said. that goes back to our universe possibly bumping into another one and crunching.

Sorry, I misunderstood what you said earlier, but now I think I understand. Anyway, it wouldn't probably do me any bad to read a little bit about this matter before commenting on the theory about bumping into another universe.

@Chris Amber: Yeah, as far as I know, it has quite a lot to do with quantum physics. I myself don't know much about it, but that was just a theory I had heard somewhere.

Well, I was wondering, if the universe would heat up, wouldn't the sides start bubbling? I mean, we would feel it somewhere won't we?

i actually don't believe it's infinite, i have another theory: the universe is one big mass of atoms, dark matter, etc. and it has some kind of blanket made out of energy. that blanket can stretch when something bounces into it but after a long long while the blanket will take all the energy out of the thing and reverse it. in that way the universe is not really infinite but not really finite either.

where does it stretch into then?

yes, thanx. but it wouldn't be a vacuum. it would be like an impossible number, like -300°C. We could imagine it only like a number, but that number would be a lie because it's impossible. (when something would have a temperature of -300°C, then it would have a negative volume and that's impossible.
