Do We Need a New Theory of Gravity?
Since Newton had his initial revelation about gravity, our understanding of this fundamental concept has evolved in unexpected ways. In this week’s episode, theoretical physicist Claudia de Rham and co-host Janna Levin discuss the ways our current understanding of gravity needs to continue to evolve.

Observations of the cosmos suggest that unseen sources of gravity — dark matter — tug at the stars in galaxies, while another mysterious force — dark energy — drives the universe to expand at an ever-increasing rate. The evidence for both of them, however, hinges on assumptions that gravity works the same way at all scales. What if that’s not true?
In this episode, theoretical physicist Claudia de Rham explains her work on an alternative explanation called “massive gravity” to host Janna Levin.
