To describe the final stages of black hole evaporation will require a theory of quantum gravity, and no such theory exists at the moment. So your question cannot be answered: we simply don't know what happens when a black hole disappears. I have seen a presentation (I'm afraid I don't have the link) where the final stages of evaporation were calculated ...

First of all try to understand what vacuum fluctuations are. Virtual pairs exist everywhere appearing and disappearing below the threshold of our detection. Every photon, every charged particle is "dressed" by the vacuum fluctuations as it goes along. The following diagrams are a shorthand, they represent integrals that have to be calculated in order to get ...

Here is the picture taken from the book Frolov, V. V. P., & Novikov, I. D. (1998). Black hole physics: basic concepts and new developments (Vol. 96). Springer. Google books we see that for black holes of large enough mass the radiation will consist entirely of massless particles. For smaller masses electrons and positrons would appear, for even ...

Some remarks : If we consider a Schwarzschild black hole, a local measure of the curvature is the square root of the Kretschmann scalar $K = R_{abcd}R^{abcd}$. If you consider the inverse of the curvature, you have : $K(r)^{-\frac{1}{2}} \sim \dfrac{r^3}{GM} \tag{1}$ On the other way, the total entropy of the black hole is : $S \sim GM^2 \tag{2}$ ...

The debate that seems to be happening right now is what does it mean that '... the formation of the black hole does not create nor destroy entropy, so the black hole must contain zero or nearly zero entropy as well.' This is correct, of course, except that the material we observe with zero or nearly zero entropy is 'Bose-Einstein condensate' (BEC) and BEC ...

Hawking Radiation can occur in conditions influenced by more than just gravity .. temperature can also influence this - (see Bogoliubov Theory of acoustic Hawking radiation in Bose-Einstein Condensates, A. Recati, N. Pavloff, I. Carusotto and Hawking radiation in a two-component Bose-Einstein condensate, P.-É. Larré and N. Pavloff) This means that gravity ...

At the event horizon, a test particle will appear to be moving at the speed of light, however due to time dilation to an external observer that particle will appear to have its time slowed to the point it's time is not advancing at all. At this point it will neither appear to travel faster than the speed of light, nor continue to advance in time. ...
