You seem to be asking two different questions here. Who is to say that a worm hole isn't merely a string in a much larger universe's brane theory? Secondly, It has been my understanding that worm holes are a shortcut between ripples or folds in space-time. Black holes are more often associated with portals through to other dimensions and/or parallel universes. Thank goodness this is true! These parallel universes will have different laws of physics in which to accomodate the preservation of information versus the destruction of information associated with matter entering the event horizon. It is only in alternate universes that conflicting laws can be explained, all while maintaining our current understanding. As far as connecting the worlds of quantum physics (brane) and relativity (wormholes) you are treading in waters marked, "Danger! you are contemplating the Theory of Everything".

It has been my understanding that wormholes are a shortcut between ripples or folds in space-time. Perhaps wormholes are merely a string in a much larger universe. Is quantum physics merely a flea on the butt of relativity? You are in the realm of the "everything theory". I think that black holes are more likely a bridge to parallel universes, some having laws similar to ours, some having vastly different laws. This is the one theory that can accomodate the argument for perpetual information retention and the apparent destruction of information occuring in a black hole.

You seem to be asking two different questions here. First of all, you could consider a worm hole as merely a string in a much larger universe's brane theory. You are entering the realm of satisfying the quantum with the relative..."theory of everything" stuff. Good luck with that. Secondly, I have always been under the impression that worm holes are a short-cut through a fold in space-time. Black holes are usually considered a portal through to alternate or parallel universes. Good thing, too because without alternate universes and their likely alternate laws of physics, the paradox of information retention versus information destruction at the event horizon would be hard to satisfy.

Not too sure about that...but in all honesty I don't believe they could exist. I mean, when a planet reaches a point where it's gravitational pull exceeds that of the outwards force and thus decreases in size, mass increases and eventually turn into a black hole (even though it's not an actual hole), it would have gravity from all sides, thus pulling everything in from all sides. Something that enters the black hole would be pulled to the center, and then there's speculation on what happens next. Does hit the center, then form part of it and increase it's mass or not?

Now put that aside for a moment and assume you managed to connect two black holes, and have an entry point and an exit point. A massive amount of matter would then be released on the other end...which will then collapse and ironically form another black hole...turning the "white hole" at the exit into another black hole...so as soon as it's open, it will be closed again...

So how will you travel through a worm-hole if it would most probably just collapse and turn into a massive black hole or form a new one?
