What Would Alien Life & Intelligences Mean?

Make a donation to Closer To Truth to help us continue exploring the world's deepest questions without the need for paywalls.

What could life be as we don’t know it? Three transitions in astrobiology. Non-life to life. Life to intelligent life. Intelligent life to technological civilization. For alien life, would Darwinian evolution hold? Fermi’s Paradox is profound: with at least 10 22 planets in the known universe, we find no evidence of alien life, anywhere, much less alien intelligence. Is there a great filter?

Featuring interviews with Carol Cleland, Richard Dawkins, Rachell Powell, Massimo Pigliucci, and Helen De Cruz.
