Liberate all the matter from a black hole

Click For Summary
The discussion revolves around the hypothetical scenario of dark energy increasing over time and its potential to liberate matter from black holes. Participants clarify that black holes are not simply containers of matter but are regions where gravity is so strong that nothing can escape once it crosses the event horizon. The idea of using infinite repulsive energy to overcome gravitational attraction is deemed unrealistic, as current physics suggests that it would require infinite force to disrupt a black hole's singularity. The conversation touches on speculative theories about the universe's future, including the "Big Rip" and cyclic models, but emphasizes that these ideas remain outside mainstream scientific consensus. Ultimately, the thread highlights the challenges of discussing speculative physics within established scientific frameworks.

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.
