Simply enough...we don't know. So far no one can say with certainty if the universe is infininte or not. WHy some people, like me believe in sphere (not a perfect sphere, but more round than square), is because when the big bang exploded. It pushed things out ward. When you blow something up underwater or blow something up in space, what shape do you get? a sphere. So we can assume that this sphere (it could have deformed) still is ever so expanding.

I am sure i got a few points wrong, I am not expert but thats the jist of why most of us believe its sphere. If indeed most of us believe ithe universe is limit. (other wise in quantum mechanics, the multiverse idea would be quite impossible, because as i figure, infinty was stretch over every parrarel dimmension).

Um, no as we see it now, we have 12 dimensions. Orginally 11 but with string theory ( m-theory) we get 12. What I personally assume, apperently some people think otherwise, is that whatever is true for last dimension will be true for next. But next will have extra properties. So seeing how the universe is 3D we can safely assume that the sphere is it in is indeed a sphere (which is 3d)....I suck at explaining this....

Null space? You mean the nothingness outside of our universe? Well assuming that the universe is limited, I should be able to conclude outisde it there shouldn't be anything, an opposite of the universe. Nothingness doesn't exist in our universe, because nothingness is nothing, outside our universe things are different. Properties and laws don't exist, no space/time, no nothing. Blankess.

There is high chance i am wrong, I am simply giving my idea of how this thing works. BUT then again, there is no way i can be wrong. This non conclusive area of science, so far, we don't have any proof for any idea. So until one prooves otherwise my ideas are just as solid as any theory out there.
