Visit https://www.economist.com/toe Today we are joined by theoretical physicist Claudia de Rham for her return appearance on Theories of Everything with Curt Jaimungal to discuss the possibility that gravity itself has mass. In this mind-bending conversation, she explores how this idea challenges long-held assumptions in general relativity and opens the door to a new understanding of dark energy and the structure of the universe. We also dive into the frontiers of cosmology, quantum gravity, and what it means to question the foundations of physics.
