Re: what will happen to particles in ergosphere of evaporating b.H.

Hi Yevgeniy

Thank you for your interesting question. Let me first point out a practical issue with with your question. The evaporation of black holes, and especially the evaporation of small black holes, produces quite a bit of energy[1]. As such, if what you describe would occur in the real world, it is likely that the intense energy burst produced by the evaporating black hole would blow away the particles.

If we ignore this, you have actually answered your own question. In empty space, particles will just move in straight lines, as their initial velocity takes them. As such, yes, the particles will behave differently than when they were in the ergosphere of a black hole, although this effect is not unique to black holes, but rather, to any object of finite mass.

I hope this answers your question.
