Are Black Holes the Ultimate Cleaners of the Universe?

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Getting "infinity" means that the model breaks down; it is no longer valid.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 cannot say for certain whether black holes are the ultimate cleaners of the universe. While Michio Kaku is a respected physicist, his statements should always be taken with a critical eye and further research should be done to confirm the accuracy of his claims.

That being said, according to current understanding, black holes are regions of space where the gravitational pull is so strong that nothing, including light, can escape. This is due to the immense mass of the black hole being compressed into a small space, creating a strong gravitational field. As objects get closer to the black hole, the gravitational force increases, and at the event horizon (the point of no return), the escape velocity is equal to the speed of light.

It is true that at the center of a black hole, the mass is compressed into an infinitely small point, known as a singularity. However, the concept of infinity is a mathematical concept and does not necessarily reflect physical reality. We currently do not have a complete understanding of what happens at the singularity, and it is an area of ongoing research in physics.

As for the idea that black holes could be a way of "cleaning up" the universe, it is important to remember that black holes are a natural phenomenon and are not controlled by any deity. They are formed when massive stars collapse under their own gravity and are a crucial part of the life cycle of galaxies. While they do consume matter, they also play a role in the formation of new stars and contribute to the overall evolution of the universe.

In conclusion, while black holes are fascinating and mysterious objects, we must be careful not to assign them supernatural or god-like qualities. They are a natural part of the universe, and further research and study will continue to deepen our understanding of them.
