| 11:00 - 12:00 Journal Club: Experiment & Phenomenology – meeting Firewalls from wormholes School PARTICLES AND ACCELERATORS Abstract: Spacetime wormholes can lead to surprises in black hole physics. We show that a very old black hole can tunnel to a white hole/firewall by emitting a large baby universe. We study the process for a perturbed thermofield double black hole in Jackiw-Teitelboim (JT) gravity, using the lowest order (genus one) spacetime wormhole that corresponds to single baby-universe emission. The probability for tunneling to a white hole is proportional to t2e?2S where t is the age of the black hole and S is the entropy of one black hole.
