If the Universe started an infinite time in the past then all of the stars would have burned out now - they have not.
If the Universe has expanded at an infinite speed then everything would have torn apart - it has not.
If the Universe had infinite mass/energy it would be solid - it is not.
The Universe is finite.

No.
There are no proofs in science (or theology).
What science has is observations and theories.
Scientific observations indicate that space is not infinite.
The only actual proofs are in mathematics.

Another thing is; the very fact galaxies move away from each other is perhaps the best proof we have to speculate a finite universe. It indicates expansion of space. They don't just move from nothing. It is suggested that they don't move at all, the gap just widens. Yes, there is a difference believe it or not. A galaxy itself isn't moving through space, space is expanding and drag these galaxies along was the space grows.
There would be no reason why galaxies would move away from each other. If space weren't expanding they'd most likely be moving toward each other due to gravity. But that's if they'd move at all. Their distance from each other is very wide and gravitational pull might not be strong enough. Inertia wouldn't allow them to move in another direction for no cause. Right now, it looks like there is no force causing them to move, that means space grows and galaxies don't move as i mentioned above.

no and probably no one can.

If you can observe and map a large enough part of it, you can determine whether or not its curvature is positive. If its curvature is positive, then it's not infinite. The last I heard, observations seemed to be suggesting that the curvature is very close to zero, so the universe may actually be infinite.

I take it you don't mean this Infinite...? If not I'm not qualified to answer this question.

can you prove that it is
2015-07-11 4:57 am
Yes. Red shifting allows us to notice a rate of entropy rising the further galaxies move away from each other.
Another thing is that all galaxies are moving away from each other in the same direction. From one galaxy you see others moving away from you. Enter another you will see the same thing.

Space-time would appear to have been much smaller than it is today, by observation. It is also observed to be expanding, the rate of expansion is not "infinite" ERGO space-time is not infinite. How's that for you?
2015-07-13 8:49 am
Well there is so much that is not yet understood about space and the universe. If anything, I think that the rate at which the universe expands has actually accelerated. For now, all we can do is speculate and create the best theory we can. As far as I know, it is continually expanding actually.
But I do wish I could provide more information, sorry :)

nope!
2015-07-11 8:29 pm
Me, no.
2015-07-11 12:20 pm
no ,any person can not do it.
2015-07-11 5:27 am
The answer is no.
2015-07-11 4:51 am
No, can you?
Cheers!

We can't see an edge. We don't even know if there are other "universes", created by their own "big bangs" so far away they haven't begun to show themselves...
2015-07-12 5:46 pm
Yep. I can also prove it's infinite at the same time.
2015-07-12 9:20 am
I cannot. However, the next question is: what is infinity?
2015-07-12 5:59 am
no we can never in our life span prove it right now with current tech.
2015-07-12 1:49 am
Why does this need proof?
2015-07-11 3:03 pm
No, maybe someday it will be proved with mathematics
2015-07-11 12:00 pm
Because I can't I say "infinite". When I (we) throw up my hands I say that & that is the meaning of "infinity". It is not an estimable number.
2015-07-11 2:57 am
Nope. Can't be done.
2015-07-11 4:03 am
No, because you cannot prove a negative.
2015-07-12 1:33 am
Well if science hasn't found the end of space year especially w the technology is we have now r then most likely there is no end to space. I guess we just hasn't found the proper use for most of it...maybe someday NASA will think of something to do with space.
