The discussion centers on the fate of the singularity inside a black hole as it evaporates, with a consensus that a singularity may not exist due to quantum mechanical effects not accounted for in general relativity. The equations of general relativity predict a singularity at radius r=0, but these do not incorporate quantum gravity, which suggests that singularities may not form. When a black hole evaporates, it is likely that spacetime will return to a state of normalcy, leaving only Hawking radiation behind.

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.Rishi Tharun said:Hello Friends... I just need a help... I want to kno what happens to the Singularity inside the black hole when it evaporates... Help me out[emoji5] [emoji5] [emoji5]
Will the spacetime return back normal when the black hole evaporates and vanishes?Nugatory said: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.
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.Rishi Tharun said:Will the spacetime return back normal when the black hole evaporates and vanishes?
