Dr. Sabine Hossenfelder is a Research Fellow at the Frankfurt Institute for Advanced Studies, where she heads the "Analog Systems for Gravity Duals" group. Bob first asks her to explain why physicists began using the concepts of "dark matter" and "dark energy" to explain their observations of galaxies. Then they discuss her June New York Times column in which she explained that existing computer models can't tell us if climate change poses an existential threat or is merely an inconvenience.
