GEB 233 was packed when I began my talk on black holes. I expected half the audience to leave in disgust after a few minutes into it, but they stuck around. Could it have been that once I started, the walls and doors of the room themselves became like the event horizon of a black hole, trapping everyone in the interior of the room? Were people attempting to come in from outside able to do so? Or, were they met by firewalls, created by breaking the entanglement between particles just outside the doors, having an energetic and violent effect on the vacuum energy outside the doors? There also is a remote chance that the audience found the confusion about black holes and the ideas being kicked around to resolve the confusion fascinating. I am going to assume the latter. Our understanding of black holes is causing some re-think of old and trusted principles of physics. Thank you to all who attended. I wish we could have provided time at the telescopes afterwards, but the clouds spoiled that part.
