Do We Need a New Theory of Gravity?

Claudia de Rham, a renowned theoretical physicist specializing in massive gravity, joins host Janna Levin to challenge conventional understanding of gravity. They discuss the implications of dark matter and dark energy, questioning if gravity operates uniformly across scales. De Rham shares insights into the historical evolution of gravity from Newton to Einstein and the role of gravitons in our cosmic understanding. Their conversation highlights how mathematics shapes theories and the joy of discovering simplicity in the complexities of the universe.
