Singularity and Black Hole

In summary, the conversation discussed the fate of the singularity inside a black hole when it evaporates. It was mentioned that there is not enough understanding of quantum gravity to accurately predict what happens to the singularity. It was also mentioned that once the black hole evaporates, only Hawking radiation will remain.

We can't be sure because we haven't actually studied the inside of a black hole... But the most likely answer is that there isn't a singularity there so the problem doesn't come up.

The equations of general relativity predict a singularity at ##r=0##, but these equations do not allow for quantum mechanical effects that only matter for very small values of ##r##. It is likely that if we did allow for these effects (which are not fully understood - we do not have a complete theory of quantum gravity) prevent a singularity from forming.

Will the spacetime return back normal when the black hole evaporates and vanishes?

That depends on what you mean by "normal" and what you're considering to be not "normal" when the black hole is there... But there won't be anything left behind except the Hawking radiation spreading out through space.
 

1. What is the singularity in a black hole?

The singularity in a black hole is a point of infinite density and zero volume, where the laws of physics as we know them break down.

2. How is the singularity formed in a black hole?

The singularity is formed when a massive star collapses under its own gravity, causing its mass to become infinitely dense and creating a black hole.

3. What is the event horizon of a black hole?

The event horizon is the point of no return for anything that enters a black hole. Once something crosses the event horizon, it is pulled into the singularity and cannot escape.

4. Can anything escape a black hole?

No, nothing can escape a black hole once it crosses the event horizon. The extremely strong gravitational pull of the singularity prevents anything from escaping, including light.

5. What is the difference between a singularity and a black hole?

A singularity is the point of infinite density at the center of a black hole, while a black hole is the entire region surrounding the singularity where the gravitational pull is so strong that not even light can escape.
