Abstract: Quantum gravity is hard, but it's not the end of the world. Or is it? In this talk, I'll give a high-level overview of recent work involving end-of-the-world branes in AdS/CFT. Gravitationally, these branes are simple hypersurfaces cutting off spacetime. Quantum-mechanically, however, they encode non-perturbative features of the dual CFT, and exhibit surprising information-theoretic properties. I'll explain how these branes are constructed, how to test the genericity and consistency of the construction, and finally, how to use it to peer inside black holes and track their evaporation. I end with some prospects for post-apocalyptic quantum gravity.
