Sean Carroll opens this AMA episode by correcting previous errors regarding Copenhagen’s location and a quantum mechanics thought experiment involving entangled particles and double slits. He then explores whether an Alcubierre warp drive could escape a black hole, concluding the question is ill-defined without proper initial conditions. The discussion continues with anthropic reasoning in multiverse models, the psychological effects of city size on attention, and why gravity waves are impractical for communication due to their weakness and lack of negative mass.
