Fay Dowker: Causal Set Theory as Quantum Gravity's Best Candidate

Fay Dowker joins us to explore causal set theory as a candidate for quantum gravity, discussing how discrete spacetime might reconcile general relativity with quantum mechanics. The conversation also delves into the implications for consciousness, non‑locality, and the legacy of Stephen Hawking’s work. Listeners gain a clear overview of the challenges and promises of this emerging framework. Theories of Everything with Curt Jaimungal features long-form, technically detailed interviews with leading researchers in physics, mathematics, consciousness, and philosophy, exploring topics at the level of active research. For academics, graduate students, and anyone seeking depth beyond popular science. SPONSOR: I subscribe to The Economist for their science and tech coverage. As a TOE listener, get 35% off!
