Liberate all the matter from a black hole

Click For Summary

Discussion Overview

The discussion revolves around the hypothetical scenario of liberating matter from a black hole using dark energy that increases in strength over time. Participants explore the implications of such a scenario, questioning the nature of black holes, gravity, and dark energy.

Discussion Character

  • Exploratory
  • Debate/contested
  • Theoretical physics

Main Points Raised

  • One participant proposes that if dark energy were to become strong enough, it could potentially liberate matter from a black hole.
  • Another participant argues that black holes are not simply places where matter is sucked in, but rather the result of concentrated mass, challenging the notion of extracting matter from them.
  • Some participants question the feasibility of infinite dark energy and assert that current understanding of black holes suggests matter cannot escape due to the escape velocity exceeding the speed of light.
  • A participant suggests that if dark energy were to increase significantly, it might release information contained within black holes, leading to a speculative scenario involving a "Multi Big Bang" theory.
  • Others express skepticism about the speculative nature of the discussion, emphasizing the need for grounding in established physics.
  • There is a suggestion that dark energy might act like a form of anti-gravity, but this is met with caution regarding the implications of such a view.

Areas of Agreement / Disagreement

Participants do not reach a consensus. There are competing views on the nature of black holes, the role of dark energy, and the possibility of liberating matter from black holes. The discussion remains unresolved with various speculative ideas presented.

Contextual Notes

Participants highlight limitations in current understanding of dark energy and black holes, noting that many of the ideas discussed are speculative and not grounded in established physics. There are references to the potential for infinite forces and the implications of escape velocity in relation to black holes.

Oddly enough the charley link in you signature, marcus,...

Imagination has driven absolutely everything we have ever done. Don't knock it so readily.

Where was I knocking imagination so readily? :biggrin: My only contribution to this thread so far has been the preceding two posts: #28 and #29.
Not being interested in somebody else's flight of fancy is not the same as knocking imagination. One has to be selective. So I reserve the right not to be interested in "big rip".

they've been looking for 10 years or more for signs that Lambda is not constant, e.g. increasing. So far the evidence that it is simply a constant of nature keeps piling up. Since 2005 we gradually hear less and less about "quintessence" and "big rip" in the professional literature. Imagination has to dance with the evidence. When they are really in step with each other you can't tell which is leading. I think that's right--something like that :wink:

I don't know anything about you but it seems abstractly speaking like a reasonable question to ask. A person could learn by asking it. I'm not sure I know enough to respond adequately but I will try a little anyway.

I'm sorry, I don't see how a question asking about jacking dark energy up to an infinite level is "reasonable". Nor how messing with the cosmological constant could teach anyone much of anything. It just seem like the normal "what ifs" we usually get here on PF that we usually don't allow.
