Are Black Holes the Ultimate Cleaners of the Universe?

AI Thread Summary
The discussion centers on the implications of black holes as described by Einstein's equations, particularly the idea that at the center of a black hole, gravity becomes infinite and time ceases to exist. Michio Kaku's claims about black holes potentially leading to the disappearance of matter are debated, with some suggesting that the breakdown of the equations indicates a flaw in the theory rather than a literal disappearance of matter. The conversation also touches on the nature of classical matter and its limitations under extreme gravitational conditions. Participants express skepticism about Kaku's interpretations, labeling them as speculative and potentially pseudoscientific. Ultimately, the discussion highlights the complexities and uncertainties surrounding black holes and the limits of current physics.

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Getting "infinity" means that the model breaks down; it is no longer valid.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.
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
