Tear space? Why not? I think, notice I said think, that that's what it does already. In addition to light, anyway.
Watch this, about black holes. Understand that, not even light can escape a black hole.
As to the other part, It is just a theory. Just like Evolution is a theory. Just like the universe is just a theory. Just like religion is just a theory. It can't be proven... yet.
This is what I believe though. Black holes, are 'portals' to another universe. The matter 'absorbed' by a black hole, is shot out the other side via a white hole. This represents our big bang. The rest, etc etc, you know.
