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.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.

How does light maintain enough energy in the visible part of the spectrum for the naked eye to see in the night sky. Also, how did it start of in the visible frequency part of the spectrum. Was it, for example, photons being ejected at that frequency after high energy particle interaction. Or does the light become visible (spectrum) after hitting our atmosphere or space dust or something? EDIT: Actually I just thought. Maybe the EM starts off as very high energy (outside the visible...
