Sara Walker is an astrobiologist and theoretical physicist who studies the physics of life's emergence and complexity. She is the author of 'Life as No One Knows It: The Physics of Life's Emergence' and explores fundamental questions about the nature of life, consciousness, and the possibility of alien intelligence.
Sara Walker explores a physics-based definition of life that goes beyond biological categories and could apply to non-carbon-based lifeforms and potential alien intelligence.
The origin of life remains one of science's greatest unsolved mysteries, with multiple competing theories about how chemistry became biology.
