#252 — Are We Alone in the Universe?

Sam Harris speaks with Neil deGrasse Tyson about our place in the
universe. They discuss our current understanding of extra-solar
planets, the prospect that there is complex life elsewhere in the
galaxy, the Fermi problem, the possibility that all advanced
civilizations self destruct, how we can detect life on
exoplanets, recent media interest in UFOs, whether a direct
encounter with alien life would change our world, the flat-Earth
conspiracy, the public understanding of science, the problem of
political partisanship, racial inequality, and other topics.
