Is an Expanding Universe Hidden Beyond Black Holes?

Click For Summary
SUMMARY

The forum discussion explores the theoretical implications of black holes, particularly the notion of an expanding universe existing beyond them. Participants assert that black holes accumulate mass from absorbed matter while losing it through Hawking radiation, leading to a paradox regarding their eventual fate. The discussion also touches on the long lifespan of black holes, estimated to be on the order of 10^67 to 10^100 years, and the misconception surrounding the dangers of mini black holes created in CERN experiments. Overall, the conversation highlights the speculative nature of black hole theories and the ongoing quest to understand their properties.

PREREQUISITES
  • Understanding of black hole physics and Hawking radiation
  • Familiarity with general relativity and spacetime curvature
  • Basic knowledge of quantum mechanics and virtual particles
  • Awareness of cosmological concepts like dark matter and dark energy
NEXT STEPS
  • Research the implications of Hawking radiation on black hole mass loss
  • Explore theories regarding the nature of spacetime and black hole singularities
  • Investigate the role of dark energy in the universe's expansion
  • Learn about the potential risks and scientific objectives of CERN's particle collider experiments
USEFUL FOR

Astronomers, physicists, and anyone interested in theoretical astrophysics, particularly those exploring the mysteries of black holes and the universe's structure.

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 through 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.
