Think like a physicist. Wonder like a human. Into the Impossible is where Cosmic Conversations happen — uniting Nobel Prize winners, iconoclasts, authors, and technologists to explore reality’s deepest questions. From AI to aliens, from biophysics to the brain, from the cosmos to the multiverse, Brian Keating, Chancellor’s Distinguished Professor of Physics at UC San Diego covers it all. If you’ve ever asked What’s out there? or What’s next?, this is where curiosity meets clarity. Learn to think like this. 🎙 Full episodes, notes & more: briankeating.com/podcast
