Confined Penrose process and black-hole bomb
Confined Penrose process and black-hole bomb
We consider the decay of a particle with some energy ${E}_{0}>0$ inside the ergosphere of a black hole. After the first decay, one of particles with the energy ${E}_{1}<0$ falls towards a black hole while the second one with ${E}_{2}>{E}_{0}$ moves in the outward direction. It bounces back from a …
