Is an Expanding Universe Hidden Beyond Black Holes?

Click For Summary
The discussion explores the intriguing idea that an expanding universe could exist on the other side of a black hole, suggesting that matter absorbed by black holes might lead to new cosmic events. Participants note that black holes grow by accumulating mass from their surroundings, while also acknowledging that they can lose mass through Hawking radiation, particularly smaller black holes that may eventually evaporate. The conversation touches on the paradox of how gravitons, if they exist, could escape a black hole's gravitational field, highlighting the complexities of gravity and spacetime. Concerns about the creation of mini black holes during CERN experiments are addressed, with reassurance that small black holes would evaporate quickly and pose no threat. Overall, the thread emphasizes the speculative nature of these theories and the limited understanding of black hole mechanics.

Well, I was wondering what we know in current physics, it was not meant as philosophy qn... That is why I asked my initial question, was just an idea.

I was wondering if someone agrees:
Is it possible that on the other side of the black hole is an expanding universe? It seems an iteresting idea to me: in our universe a star collapses onto itself with an explosion, creating a black hole and on the other side a big bang happens with matter sucked in from our side, falling out on 'the other side'.. If nothing can escape the black hole it must be going somewhere...

A separate question: does a mass of the black hole keep increasing throught it's life? And does the black hole ever 'die'?

I definitely think that this is a possibility (that the other side of a black hole is an expanding universe). You'll see a lot of people in physics-related occupations that will tell you "no" or "that's not possible" because they think so analytically about singularity and all of this stuff falling into a black hole... For some reason Newton's third law comes to mind. If all of this matter is falling into a black hole...and space is being warped by this singularity...doesn't it make sense that somewhere (if not on the other side of the black hole), an equal and opposite reaction is occurring? It's certainly not from radiation...it would have to be a reaction just as BIG as the black hole itself, right? Don't think numerically. It's not about numbers. It may seem incredibly simplistic, but sometimes the simplest answer can be the correct one. ;) http://www.beadedlanyards.info

We do not know what lies inside the event horizon of black holes. Other universes, or fairies, are pretty much equal possibilities.
