“When it comes to the world around us,” Lisa Randall has written, “is there any choice but to explore?” As one of the most influential theoretical physicists working today, she’s interested in the interconnectedness between fields that have previously operated more autonomously: astronomy, biology, and paleontology. She’s pursuing a theory that “dark matter” might have created the cosmic event that led to the extinction of the dinosaurs — and hence humanity’s rise as a species. We learn what she’s discovering, as well as the human questions and takeaways her work throws into relief. This interview is edited and produced with music and other features in the On Being episode “Lisa Randall — Dark Matter, Dinosaurs, and Extra Dimensions.” Find more at onbeing.org.
