For instance, it is thought black holes house an entire universe with its own time scale inside, the implication being there are other universes.

One definition of universe is 'All there is'.
This definition doesn't support the idea of a universe within a black hole just because this black hole universe resides totally within ours.
To make the discussion of this matter continue we have to have a better definition of 'universe' in order to make it a meaningful diskussion.

Originally posted by FabianFnasAccording so some theories, you are right about that, but the boundry to that place is called the event horizon, beyond which you are part of the inside of the black hole and permenantly disconnected from our universe, in fact, if you had instrumentation that could magically watch events in our universe, you would see our universe meet its destiny, all the while your univese would have its own disconnected time rate, that alone is a disconnect from our universe as we count time as one of the dimensions of space.

The thougt that our universe is the content of another black hole the idea seems rediculous. If not there is two cinds of universes - one inside a black hole and one, completely different outsi ...[text shortened]... o, we can't call inside of a black hole as an universe of the same kind as our own universe.
Originally posted by FabianFnasYour working definition fits mine, a box with its own set of physics laws inside. That is what present theory says, there can be other boxes with its own set of laws, say places where the speed of light is one meter per second, or where the time scale compared to ours is a million times faster or a million times slower. The overall picture according to this kind of theory is called the 'Multiverse'.
If we don't agree what definition of the very fenomenon 'universe' is - then we don't know what we are talking about.
The key question before we can say anything is - "What is a universe?"
Originally posted by FabianFnasNot entirely. Theory has it these multiple universes have one connecting glue: gravity. According to these theories, gravity is so weak compared to magnetism for instance (a refrigerator magnet holds back the gravitational pull of the whole planet for example), precisely because it crosses dimensions, the power of gravity thus becomes shared by all these dimensions and therefore each set of dimensions only feels a shared piece of the power of gravity. I suspect that makes for an open door between dimensions for sufficiently advanced civilizations. Just a personal speculation.
So the universes are isolated from each other?
Originally posted by sonhouseWell, this theory is not more than speculations. And should be treated as such. As a brain-teaser over a hefty glass of beer for physicists theoreticans local pub, inside or outside university campus.

Originally posted by FabianFnasThere are testable ramifications to the gravity spread amongst dimension theory which is being vigorously tested as we speak.

A complete universe inside of black hole? No way in my humble opinion.
But the discussion is fun.
