1.4.6 Martin Rees: Astronomer Royale
Channel: Are We Alone?
Date: 2021-10-04

Martin Rees (cosmologist and Astronomer Royal) claims that there are many planets more or less like the Earth, but we don't know how life got started. For the first time, serious people are now working on the origin of life and the question Are we alone? Inorganic intelligence may supersede us. If we can survive and our SETI search fails, Earth can seed and colonize the entire galaxy with post-biological life.
