Interview with Prof. Sean Carroll, Research Professor of Physics at Caltech and an External Professor at the Santa Fe Institute. We mainly talk about quantum spacetime: the idea that  our familiar spacetime might be actually emergent from some complex quantum mechanical system. We cover entanglement, decoherence, entropic gravity, the AdS/CFT correspondence, string theory, black holes, along with several philosophical questions concerning these topics, including reduction and emergence, substantivalism vs. relationalism, monism, and much more.
