: At the risk of sounding arrogant I'm going to assume that when you said I know few things you meant I know a few things. If I am wrong, correct me. However falling back on your theory about our three-dimensional universe being curved in a higher spacial dimension and having finite size while going on forever, this is one of the most interesting theories in cosmology (in my opinion) but is hardly new. I really couldn't say whether it is true or not, it seems possible but would be difficult to prove without hoping in a spacecraft, firing up your special many-times-faster-than-the-speed-of-light-engines and flying off in any one direction in space. If you end up back where you started in however many years (could be thousands or trillions or more) you know the universe curves back on its self life a four-dimensional sphere, a sphere on whose surface we exist (remember that a four-dimensional surface would be three-dimensional). We may know someday, but that will likely be centuries from now. However if indeed the universe does curve back on its self this brings up some interesting ideas. If the universe is expanding and will do so forever, for example, then won't all that matter just end up right back where it started, ie. another Big Bang? There are other things I'm sure as well that are related to this, but at the moment I can't really think of any. I know a bit about this because I read a lot and think a lot. Hope this helps some.

-Paul When I said that you know few things I meant that you know more than just few things :o)

I know that this theory isn't new, I mentioned Albert Einstein. I read this in his theory of relativity (I don't know if this is the right translation since I am not from English speaking teritory, so I appologize if the translation is incorrect).

Anyway, this is the most reasonable theory about space I ever heard, and I mostly agree with you. But there is something in your post I am not so agreeable. The part that space will never BigBang again.

In center of the galaxies exists a giant black hole that sucks all matter(and spacetime)in it. Maybe when all of the matter and spacetime is being "sucked in" it will "bigbang" again to create a new universe. That's what I think, I didn't read so much so I am not sure I am the only one who think so. So I am asking all of you to agree or disagree with me.

Thanks.
