Sam Harris speaks with Sara Imari Walker about a scientific understanding of life. They discuss the contributions of physics to this topic, Erwin Schrödinger, the inadequacy of standard definitions of life, the prospect of "artificial" life, the role of information, constructor theory, assembly theory, the space of all possible structures, a "block universe," the existence of abstract objects like numbers, the Fermi paradox, the likelihood of life elsewhere in the universe, experiments that could decide how likely life is to emerge, the possibility of a Great Filter, the number of Earth-like worlds, and other topics.
Sara Imari Walker is an astrobiologist and theoretical physicist. She is the deputy director of the Beyond Center for Fundamental Concepts in Science and a professor in the School of Earth and Space Exploration at Arizona State University. She is also a fellow of the Berggruen Institute and a member of the external faculty at the Santa Fe Institute. She is a recipient of the Stanley L. Miller Early-Career Award for her research on the origin of life, and her research team at ASU is internationally regarded as being among the leading labs aiming to build a fundamental theory for understanding what life is. Her research has been featured in Scientific American, Quanta Magazine, and a variety of other international outlets. Her book, Life as No One Knows It: The Physics of Life's Emergence, is available now.
