B What Happens to the Singularity Inside a Black Hole When It Evaporates?

AI Thread Summary
The discussion centers on the fate of the singularity inside a black hole as it evaporates. Current understanding suggests that a singularity may not exist due to quantum mechanical effects that are not accounted for in general relativity. These effects could prevent a singularity from forming, meaning the issue may not arise. When a black hole evaporates, it is believed that only Hawking radiation remains, with no remnants left behind. Ultimately, the nature of spacetime's return to "normal" is subjective and depends on the context of the black hole's presence.

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]

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.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
