My student Kiran Bist, an undergraduate math major at William Carey University, presents a series of seven videos about quantum gravity, focusing on the theory of observation for discrete models of spacetime. This project is part of the FQXi Physics of the Observer Program, supported by the Silicon Valley Community Foundation.
This video, number 2 in the series, outlines general advantages of discrete spacetime models, and describes the notions of metric recovery and the causal metric hypothesis. The description is closely related to causal set theory. It emphasizes a point of view based on early work of Stephen Hawking and David Malament, and developed by Bombelli, Lee, Meyer, and Sorkin.
