Firewalls from wormholes in higher genus

A bstract 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 − 2 nS E e 4 π E n − 1 E 2 n 2 − n − 9 / 2 t 4 n 2 − 2 n − 5 , where t is the age of the black hole, and S and E represent the entropy and energy of the black hole, respectively.
