Is an Expanding Universe Hidden Beyond Black Holes?

Click For Summary

Discussion Overview

The discussion revolves around the speculative idea of whether an expanding universe exists on the other side of black holes, alongside inquiries about the nature of black hole mass and their potential to 'die' or evaporate. Participants explore theoretical implications and paradoxes related to black holes, gravitation, and quantum mechanics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants propose that a black hole could lead to an expanding universe on the other side, suggesting a connection between black hole formation and a big bang.
  • Others argue that if black holes retain the mass they absorb, they cannot simultaneously lose mass to another universe, which raises questions about the sustainability of such a universe's expansion.
  • There is a discussion about whether black holes continuously increase in mass throughout their existence, with some noting that they can lose mass through Hawking radiation, particularly smaller black holes.
  • One participant raises a paradox regarding how gravitons, if they exist, could escape a black hole's gravitational field, questioning the nature of gravity and spacetime distortion.
  • Concerns are expressed about the public perception of black holes created in experiments at CERN, with some suggesting that small black holes would evaporate quickly and pose no threat.
  • A later reply discusses the distinction between stellar mass black holes and hypothetical quantum black holes, questioning the relevance of Hawking radiation in the context of CERN experiments.
  • Another participant emphasizes that the panic surrounding mini black holes is largely media-driven and not based on scientific understanding.

Areas of Agreement / Disagreement

Participants express a range of views on the nature of black holes and their implications, with no consensus reached on the existence of an expanding universe beyond black holes or the specifics of black hole mass retention and evaporation.

Contextual Notes

The discussion includes speculative ideas that depend on theoretical models of black holes and quantum mechanics, with participants acknowledging the limitations of current understanding in these areas.

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.
