Lisa Randall Dark Matter, Dinosaurs, and Extra Dimensions
\u201cWhen it comes to the world around us,\u201d Lisa Randall has written, \u201cis there any choice but to explore?\u201d As one of the most influential theoretical physicists working today, she\u2019s interested in the interconnectedness between fields that have previously operated more autonomously: astronomy, biology, and paleontology. She\u2019s pursuing a theory that \u201cdark matter\u201d might have created the cosmic event that led to the extinction of the dinosaurs \u2014 and hence humanity\u2019s rise as a species. We learn what she\u2019s discovering, as well as the human questions and takeaways her work throws into relief.
