INSTABILITY OF THE BLACK HOLE HORIZON WITH RESPECT TO ELECTROMAGNETIC EXCITATIONS

Abstract

Analyzing exact solutions to the Einstein–Maxwell equations in the Kerr–Schild formalism, we show that the black hole horizon is unstable with respect to electromagnetic excitations. Contrary to perturbative smooth harmonic solutions, the exact solutions for electromagnetic excitations on the Kerr background are accompanied by singular beams which have very strong back-reaction to the metric and break the horizon, forming the holes which allow radiation to escape from the interior of the black hole. As a result, even the weak vacuum fluctuations break the horizon topologically, covering it by a set of fluctuating microholes. We conclude with a series of nontrivial consequences, one of which is that there is no information loss inside of the black hole.
