Avi Loeb is an Israeli-American theoretical physicist who works on astrophysics and cosmology and is a Professor of Science at Harvard University. He had been the longest serving chair of Harvard's Department of Astronomy, founding director of Harvard's Black Hole Initiative and director of the Institute for Theory and Computation (within the Harvard-Smithsonian Center for Astrophysics). In July 2021, Avi became head of The Galileo Project. The project was inspired by the detection of ʻOumuamua' and by release of the Office of the Director of National Intelligence report on Unidentified Aerial Phenomena (UAP). In this episode, Ben and Avi discuss how Oumuamua (the first interstellar object detected to pass through the solar system) could be space junk or it could be a message in a bottle from an extra terrestrial civilisation. They discuss the importance of interstellar archeology and why we should be looking further for evidence that we are not the only sentient beings in the universe!
