Ever wondered where all the aliens are? It’s actually very weird that, as big and old as the universe is, we seem to be the only intelligent life. In this episode, Josh examines the Fermi paradox, and what it says about humanity’s place in the universe. (Original score by Point Lobo.) 

Interviewees: Anders Sandberg, Oxford University philosopher and co-creator of the Aestivation hypothesis; Seth Shostak, director of SETI; Toby Ord, Oxford University philosopher.
