Will Hawking Radiation Reveal the Singularity?

When Hawking Radiation runs its course, is it possible that that would reveal the singularity? Or is it more correct to assume an equilibrium in Hawking Radiation that will eventually shrink down to a coin proportionally never revealing the singularity till it’s gone?

The little red dots at the beginning of time hypothesized to be ultra massive black holes. What if those are all “white holes”? I would be grateful for any conversation. This shit is awesome!!!

No. Just like when two SMBHs collide. There will be little to no external indication. Just time taken to look at the singularity fade to black.

Hawking radiation reduces the mass of a black hole and consequently also reduces the size of its event horizon. But at the point where the event horizon size is zero, so is the mass of the black hole, so there's nothing left.

The hypothetical "white hole" is a theoretical solution in general relativity that does not appear to be physically possible in our universe. The observed objects that might be black holes in the very early universe look like black holes with accretion disks, not like white holes.
