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 ...

There is no 'escape velocity' inside the black hole, the singularity is in the future of all observers crossing the horizon the black hole and is thus unavoidable. Historically, application of Newtonian dynamics to the light of massive bodies goes back to works of John Michell and Pierre-Simon Laplace (note that light then was thought to be corpuscular, ...

It's true that for a Schwarzschild black hole the radius of the event horizon is at the distance where Newton's law tells you the escape velocity is the speed of light. However you should not let this apparent success lead you into thinking that Newton's law has anything useful to say about black holes. For a start the Schwarzschild radius $r$ is not the ...

The simplest answer is that the horizon doesn't hold the charged particles, but rather, the information about the charges of particles that have fallen into the horizon lives on the horizon itself. In simpler terms, the electric monopole moment of all of the matter inside of the horizon can be inferred from the geometry and field in a neighborhood of the ...

As something falls towards the event-horizon Lorentz transformation on the object becomes apparent to an outside observer. Specifically, space contracts increasingly tighter as the object nears the event-horizon; time for the object slows, slowing to the point that it either appears stopped relative to the age of the universe, or is actually stopped; all ...

At the event horizon, the person getting sucked in will see light twice as fast. Then as he falls in he will eventually see light 3 times as fast, then 4 times as fast, then 5 times as fast, until light seems to be infinitely fast and time starts to grow infinite to him, and probably he will seem to take a split-second to fall in, then he will be destroyed ...

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 ...

Well, this is by no means settled, but that's ok (meaning any answer is likely going to be seen as controversial until further observation provide more data). John Rennie's answer doesn't appear to address whether or not singularities actually form in the first place; he does suggests that few skeptics would argue this, but in fact a few have (David ...

The fine-structure constant is not determined by magnetic and electric field strengths, but by other universal constants: $$\alpha=\frac{e^2}{\hbar c}$$ (using cgs here because I'm an astrophysicist). This has a value1 of $\sim1/137$. 1 - There is some debate as to whether $\alpha$ is indeed a constant; some of claimed variations over large epochs (Gyr ...
