Professor Avi Loeb is a former Chair of the astronomy department at Harvard University, founding director of Harvard's Black Hole Initiative and director of the Institute for Theory and Computation at the Harvard-Smithsonian Center for Astrophysics. He is also the head of the Galileo Project - the Systematic Scientific Search for Evidence of Extraterrestrial Technological Artifacts. We talk about the US government's "secret retrieval program" testimony by David Grusch, UFO and UAP sightings, the search for Alien Civilisations, space trash from possible neighbours.... and Professor Loeb's hunt for interstellar objects in the Pacific Ocean.
