I think it's about combining general relativity & quantum mechanics right? I will definitely take a deep look into it. Thanks
No, it’s not. It’s more of looking for answers. It was nice hearing your opinions too 🫂
QM and GR are the two most successful theories of physics that we have. Both are responsible for predictions that agree down to many, many decimal places.
And yet the two theories are utterly incompatible. GR presumes that space is continuous, and QM suggests that space, time, mass, etc are quantized. Or to say this differently (and not really accurately), GR is the domain or real numbers. QM is the domain of integers.
Because of this incompatibility there are predictions made by QM that differ from GR by over 100 orders of magnitude. This is very embarassing.

The Black Hole information paradox comes in many forms.
1. QM says that information cannot be destroyed; but information entering a black hole can never come out so it is effectively destroyed from our point of view.
2. General relativity says that nothing can ever be seen to actually enter a black hole. Time slows down, relative to us, as objects approach the event horizon. Time stops (relative to us) AT the event horizon. So, according to GR, no information ever actually enters the black hole.
As an aside, the matter that we see moving closer and closer, but never entering, the event horizon is massive, and cannot move at the speed of light. This matter is not the "spin" of the black hole itself.
Of course all this makes my head hurt.
