156 - Fay Dowker: Wormholes, Quantum Gravity, and Causal Set Theory

Fay Dowker is Professor of Theoretical Physics at Imperial College London, where she works broadly on quantum gravity, and more particularly on an approach called causal set theory that takes the most basic pieces of the universe to be atoms of spacetime. In this episode, Robinson and Fay begin by discussing her studies with Stephen Hawking and their work on wormholes before turning to quantum gravity and causal set theory. Fay is also a faculty member at the John Bell Institute for the Foundations of Physics. If you’re interested in the foundations of physics—which you absolutely should be—then please check out the JBI, which is devoted to providing a home for research and education in this important area. Any donations are immensely helpful at this early stage in the institute’s life.
