Firewalls from wormholes in higher genus

Abstract

An old black hole can tunnel into a white hole/ firewall by emitting large baby universes. This phenomenon was investigated in Jackiw-Teitelboim (JT) gravity for genus one. In this paper, the focus is on higher genus corresponding to emitting more than one baby universe ($n>1$). The probability of encountering a firewall or tunneling into a white hole after emitting $n$ baby universes is proportional to $e^{-2nS(E)}{e}^{4\pi \sqrt{E}(n-1)}{E}^{2n^2-n-9/2}{t}^{4n^2-2n-5}$, where $t$ is the age of the black hole, and $S$ and $E$ represent the entropy and energy of the black hole, respectively.
