Introduction
You have an origin of life event. It evolves for 4 billion years, at least on our planet. It evolves a technosphere. The technologies themselves start having this property we call life, which is the phase we're undergoing now. It solves the origin of itself and then it figures out how that process all works, understands how to make more life, and then can copy itself onto another planet so the whole structure can reproduce itself. The following is a conversation with Sara Walker, her third time in this podcast. She is an astrobiologist and theoretical physicist interested in the origin of life and in discovering alien life on other worlds. She has written an amazing new upcoming book titled Life As No One Knows It, The Physics of Life's Emergence. This book is coming out on August 6th, so please go pre-order it now. It will blow your mind. This is The Lex Fridman Podcast. To support it, please check out our sponsors in the description. And now, dear friends, here's Sara Walker.
