Discussion Overview

The discussion revolves around the nature of black holes, particularly focusing on the implications of Einstein's equations and the concept of singularities. Participants explore the validity of claims made by Michio Kaku regarding the behavior of matter and gravity at the center of black holes, as well as the philosophical implications of such phenomena.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant questions the accuracy of Michio Kaku's statements about black holes, particularly regarding the concept of infinite gravity and the idea that matter may disappear.
  • Another participant suggests that reaching "infinity" in equations indicates a breakdown of the model, implying that physical significance should not be attached to such breakdowns.
  • A different participant raises a question about the quantum mechanical reasons that might prevent matter from contracting to infinity under immense gravity, suggesting that classical matter cannot reach such extremes.
  • There is a discussion about the implications of a potential dense core at the center of a black hole versus the idea of infinite density, with speculation on both sides.
  • One participant asserts that when a theory breaks down, it indicates the theory is wrong, but does not imply that the universe itself breaks down.

Areas of Agreement / Disagreement

Participants express differing views on the implications of Kaku's claims and the nature of black holes. There is no consensus on the validity of the statements made or the interpretations of the equations involved.

Contextual Notes

Participants highlight the limitations of current theories when discussing black holes, particularly regarding the assumptions made about gravity and matter at singularities. The conversation reflects ongoing uncertainties and speculative reasoning in the field.

Who May Find This Useful

This discussion may be of interest to those exploring theoretical physics, particularly in the context of black holes, general relativity, and the philosophical implications of singularities.

I watched a video of Michio Kaku saying that according the Einstein's equations of black holes, physics literally breaks down into nothing. I just wanted to ask how accurate the things he says are.

For example he states that the mass of the black hole being M and R describes the distance from the black hole, but when R is equal to 0. You simply get infinity.

So he states that the very centre of a black hole, according to Einstein's equations gravity would be infinite and time itself completely stops. Also he says that all the mass of a black hole, is contained within an infinitely small, infinitely dense point that takes up exactly 0 space at all.

So if this is true, could we argue that the matter simple dissapears? As in literally no longer exists?

Maybe black holes are "gods" way of cleaning up the universe, getting rid of things he no longer likes the look of :D

Getting "infinity" means that the model breaks down; it is no longer valid. It's best not to try to attach physical significance to every quirk of the equations.

Be aware that Kaku is, shall we say, eccentric. Which is to say that he frequently finds himself peddling pseudoscience.
 
What is the quantum mechanical reason that would keep physical matter from contracting to infinity or near infinity in the presence of immense gravity? Classical matter can't contract anywhere near such proportions but where can i find such classical matter made of classical particles?

So he states that the very centre of a black hole, according to Einstein's equations gravity would be infinite and time itself completely stops.
He's taking a small bet and imo he knows what he stakes. He's bold and AFAIK Einstein has been his role model and he'd rather be in the innovators camp than in the 'don't know camp'. It's speculation both ways - that there could be an extremely dense classical-like core at the center of a black-hole or 'size' that converges to infinity.

So if this is true, could we argue that the matter simple dissapears?
Why is this more bothersome than space(time) contracting in the presence of large mass?

When the theory breaks down, it means the theory is wrong. It doesn't mean that the universe breaks down.
