Description

Jim talks with Sara Walker about the ideas in her new book Life as No One Knows It: The Physics of Life's Emergence. They discuss Sara's path from theoretical physics to astrobiology, the biggest scientific questions, philosophy of science & theory development, historical approaches to origin of life research, Schrödinger's negative entropy concept, Prigogine's dissipative systems, information as a causal force at life's origin, emergence as a scientific concept, constructor theory of information, Assembly Theory as a framework for detecting life, assembly index & copy number as measurable properties, complexity vs randomness, the physical nature of time in complex systems, how Assembly Theory redefines life beyond Earth-centric definitions, planetary-scale perspectives on life's origins, measurements of exoplanet atmospheres, addressing the error catastrophe problem, Sara's collaboration with Lee Cronin, the application of Assembly Theory to minerals & planetary atmospheres, the Fermi Paradox & observational horizons, constraints on Drake equation parameters, and much more.
