Can Black Holes Create Interdimensional Bridges to Other Universes?

[cattatomic]

I just wanted to ask and I'm sure I'm wrong but i thought of it last night. if some models explain a mutlieverse (such as m-theory), is it possible that black holes in one universe are white holes in another universe? now i am no physicist, but as a lay-man thinking if a black hole warps space in such a way could it "break through" or interact with another universe and create a white hole and there for a new universe?

i just had this thought and want to know why it would or would not be possible or plausible.

It is possible that some black holes in this spacetime region could (out the bottom so to speak) be BIG BANGS creating another spacetime region.

this was proposed by a famous physicist John Archibald Wheeler (who was Richard Feynmann's PhD advisor and mentor at Princeton, and who co-authored with Feynmann).
Later the idea was taken up by Lee Smolin. Who wrote papers about it in 1993 and 1994, then a popular book about it called The Life of the Cosmos.

Smolin adapted the idea as an empirically testable way to EXPLAIN how, if string thinking is unable to come up with a principle for selecting one out of millions of possible versions of physics (and is thus not really predictive) you might still explain how we got the observed parameters by EVOLUTION.

That is, regions of spacetime can reproduce by..have to go, back later

by reading your lines i think that you have studied the membrain theory of two universe.the things that we r talking about r totally theorotical.but predictions can be made about. don't worry ! i m with u!

I thought that the idea of a white hole or wormhole was mostly ad hoc, and that it was extremely unlikely any existed. We should probably go further to unite general relativity and quantum mechnanics before speculating and what happens when matter enters a black hole, yes? Or do I not know what I am talking about?

I agree with the general sense of what you say----they are speculative ideas based on applying classical General Relativity where it may, in fact, not be applicable. Dubious, if not precisely ad hoc.

...should probably go further to unite general relativity and quantum mechnanics before speculating and what happens when matter enters a black hole, yes? Or do I not know what I am talking about?

Further than what? is the question. Certainly you sound like you know something about this, and any advances in understanding what happens down hole is going to depend on making progress in quantum gravity----quantizing General Relativity.

So I agree basically, but at the same time i see progress being made at quantizing GR and some interesting quantum black hole bounce, and big bang bounce models, being developed. The unresolved issue now is whether and how these models fit together, so that (if they fit) one could lead to the other.

In other words can a black hole collapse lead to a big bang creating a separate expanding spacetime region?

If anyone wants links to recent technical papers about quantum bang and hole models (Ashtekar et al, Gambini et al, and others) just ask.

It is good to be cautious, but not so cautious that you ignore signficiant advances.

If you want to know who the currently most highly cited researchers are in quantum gravity as applied to cosmology, there's a thread about it. I got stats on recognized leading people and some others. these would be the people who are currently addressing these problems of what happens down a black hole, what happened before the big bang.

Here is that thread "Who the top quantum cosmology researchers are."

It gets updated, so the last post on the thread is the one to look at. I just updated it today:

Here are the citation totals as of 28 December 2007. Only papers published since 2002 which have received 35+ cites are tallied.

Bojowald 737
Singh 477
Ashtekar 409
Steinhardt 351
Reuter 86
Hawking 71
Veneziano 39

What you are thinking of is an interdemintional bridge or conduit. White holes are not possible. They are only possible in math, but not in space. I do, however believe in the m-theory.
