A Kerr to Schwarzschild to white transition

[javisot20]

TL;DR

Is ther a probability greater than 0 that a "Kerr to Schwarzschild to white transition" will occur during the thermal death of the universe?

I ask about the union of two different results,

-"Kerr to Schwarzschild transition during the thermal death", the idea of the complete loss of rotation of a black hole before evaporating, a result that I will assume is classic (semiclassic)

-"Black to white transition", known results of LQG where a Schwarzschikd black hole transitions to a Schwarzschild white hole.

I ask if from a theoretical point of view both results can be united, and then ask if the ideal conditions for such a transition to occur in the universe have ever existed or will exist.

You cannot transition to a white hole. A white hole is the beginning of time. It is always in the past, never the future.

Do you have references for either of these?

known results of LQG

DIscussions of quantum gravity belong in the Beyond the Standard Models forum, not this one.

Is not a discussion about quantum gravity, i'm not discussing the LQG result. The result I need to discuss is "Kerr to Schwarzschild transition", wich is a semiclassical result.
The black to white transition of LQG is a well-know result that would we simply couple to the other result, but is not the central point of the doubt.

Basically the transition is achieved trought quantum effects describe by LQG, but I repeat, this is not my doubt.

This is not the doubt, and is not true.

"Semiclassical" is still out of scope in this forum. This is the special and general relativity forum, which means fully classical, not "semiclassical".

The black to white transition of LQG is a well-know result

If so, then you should have no trouble providing the reference that I have asked for, as you are obligated to do according to the rules that you signed up to when you joined PF.

This is not the doubt, and is not true.

In this forum, it is. See above.

@javisot20 I have closed this thread for moderation for the time being. If you have a reference for the two results you say you want to combine, please PM them to me. If they look reasonable, I will move this thread to the appropriate forum and reopen it. If you are not able to provide valid references as a basis for discussion, this thread will remain closed.
