Is space infinite?

Question

Is the cosmos infinite? Consider M-theory, which leads to the idea of parallel universes. I know alot of people like to bring up cosmic background radiation and other theoretical explanations for why the universe is "finite" and expanding into empty space at the speed of light. If the universe is expanding into "empty space"(key word: SPACE), then how is it finite? How is it infinite? I truly believe that the cosmos is neverending and infinite. Remember, we are only abserving a small portion, about 200 light years away, of our "galaxy" and there are billions if not more of these galaxies. If the theory of parallel universes is true then there are big bangs happening all the time and universes are infinitely creating and expanding in and of themselves. I am asking people to explore the idea. Please do not just say, the universe is finite and base your claim on theoretical evidence. We are only observing a portion. Our technology is primitive compared to what lies in the future

Answer 1

I agree with you.  We have no way of knowing what may be out past the known universe.  This universe may continue past what we have been able to detect.  There may be empty space, additional universes, or something of which we have no concept.

Answer 2

Since the matter in space curves it, and you can't go faster than light, there is no way to escape it, you will curve back on yourself.  Kind of like being in a black hole.    So in this sense, it is finite.

Answer 3

everything must have an end but if it space does have an end then what is beond that end we just dont know but i think someday we will my personal belief is that there is TRUE nothingness but then agian what is beyond that and that and that it will just go on and on and i dont think the question will be awnsered for 100s of thoushands of years
