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).Mapping the Heavens: https://a.co/d/02HPcMB1OUTLINE00:00 A Paradox of Cosmology06:16 Investigating Invisibilia11:25 The Sociology of Astrophysics16:52 Phenomenology in Physics19:47 What Is the Mystery of Dark Matter?29:07 The Problem of Dark Energy36:38 Models and Simulations46:17 Modifying the Standard Model to Explain Dark Matter58:20 The Crisis in Dark Matter01:12:22 Alternative Explanations of Dark Matter01:19:51 Fine-Tuning and the Multiverse01:25:24 Black HolesRobinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University, where he is also a JD candidate in the Law School.
