278 - Priyamvada Natarajan: The Mystery of Dark Matter

Priyamvada Natarajan is the Joseph S. and Sophia S. Fruton Professor of Astronomy and Professor of Physics at Yale University, where she is also the Chair of Astronomy. Priya researches broadly across astrophysics and cosmology; some topics she has worked on include gravitational lensing, black hole physics, the philosophy of science, and dark matter. In this conversation, Priya and Robinson largely stick to the latter. They discuss her interest in cosmology writ large, as well as how the scientific community tackles the unknown. Priya’s most recent book is Mapping the Heavens: The Radical Scientific Ideas that Reveal the Cosmos (Yale, 2016).
