Are we alone in the universe? (science audio with Neil deGrasse Tyson).
Neil deGrasse Tyson joins us to chat about that ever-fascinating topic… are we alone in the universe?
Sam Harris is the chap in the hot seat, discussing with Neil 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, and how a direct encounter with alien life might change our world?
