Hi Ibbo... welcome to the site. As I mentioned in the post immediately previous to yours, ignorance isn't a problem if someone is working hard to eliminate it. I'm truly ignorant on all manner of subjects, but I try everyday to lessen it's role in my life. Anway, you had a bunch of questions, and I'll only work at those I feel confortable enough to explain.

There is a bit of semantics (word meaning issues) involved with this. The term "universe" conjures up thoughts of an all encompassing entity, and if it is truly "all encompassing" then to think of something outside of it is strange. However, if you were to say "could a *portion* of the universe travel through a wormhole (if wormholes are truly possible in anything more than theory and math), then I'd say certainly (with slight trepedation).
Thing with black holes (and worm holes) is that we are still trying to figure it all out. We've come a long way, and we can say how many things about them work and predict other aspects about them, but "certainty" is a big word. At best, we may only have a "best guess approximation."

There may be other sources too, but recently at
the Chandra Xray Observatory work was done showing that black holes roughly 100 million solar masses or greater have been forced to stop growing due to a lack of infalling material... the universe forced annorexia on them.
Personally, I try to refrain from making a final judgment because the universe is a big place, and we've learned so many things in the last few millenia that anything may be possible. Perhaps these uber black holes are just resting, like we do after a big thanksgiving meal, but they are getting ready for dessert and leftovers...

And (there is ALOT of presuposition with this) could this be what scientists claim to be the big bang?

I'll give that an absolute, definite, 100% maybe.

Nobody really knows yet (with any certainty) what happens inside a black hole. Currently, physicists are working hard to combine general relativity (the very large) with quantum mechanics (the very small) into something that has been termed by some "quantum gravity." This is still as yet ill understood, even by leading experts and brainiacs... so don't be too hard on yourself if you're struggling bringing all the concepts together into a simple picture.
There is likely much overlap between your ideas and others, but consensus is no indicator of fact. Just keep your mind open and thirsty... keep studying and keep reading and keep trying... No matter how confused you might get.
Okay, that was a really long post... sorry 'bout that. In sum, welcome to Hypography. Enjoy yourself.
