Dark Matter and the Dinosaurs: The Amazing Interconnectedness of the Universe

“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.
