Avi Loeb is Frank B. Baird Jr. Professor of Science in the Department of Astronomy at Harvard University, and former chair of the department. Before joining Harvard he spent fifteen years working in theoretical astrophysics at the Institute for Advanced Study in Princeton. He is also the Director of the Institute for Theory and Computation, the Founding Director of the Black Hole Initiative at Harvard, and Head of the Galileo Project. In this episode, Avi and Robinson discuss his controversial and compelling research on—and theories about—Oumuamua, a comet that passed through the solar system in 2017, and which Avi believes was a spacecraft of extra-terrestrial origin. They also talk about the likelihood of life outside earth, Avi’s current investigations into the same, and his upcoming book Interstellar: The Search for Extraterrestrial Life and Our Future in the Stars, which will be released on August 29, 2023.Interstellar: https://a.co/d/8Or10aMAvi on Medium: https://avi-loeb.medium.com  OUTLINERobinson’s Website: http://robinsonerhardt.comRobinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University.
