David Kipping is a Professor of Astronomy at Columbia University,
where he runs Cool Worlds Lab and researches planets and moons
that revolve around stars other than our own, in addition to his
own work on the search for—and theorization about—alien life. In
this episode, David and Robinson have a wide-ranging conversation
about extraterrestrials. They discuss alien civilizations,
propulsion, megastructures, Oumuamua, quantum immortality, Dyson
spheres, simulation theory, ancient aliens, and much more. David
also runs the YouTube channel Cool Worlds Lab, where he has
produced many videos on these topics.
