Astrobiologist and theoretical physicist Sara Imari Walker shares an intriguing new scientific theory that explains what life is and how it emerges. What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like.

Walker's latest book Life As No One Knows It: The Physics of Life's Emergence, is available for purchase now.

Sara Imari Walker is an astrobiologist and theoretical physicist interested in the origin of life and discovering alien life on other worlds. She is 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 the 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.

Harvard and MIT's influential humanist chaplain Greg Epstein discusses his new book, Tech Agnostic: How Technology Became the World's Most Powerful Religion, and Why It Desperately Needs a Reformation. In our tumultuous era of religious extremism and rampant capitalism, Tech Agnostic offers a new path forward, where we maintain enough critical distance to remember that all that glitters is not gold—nor is it God.

Greg M. Epstein serves as Humanist Chaplain at Harvard & MIT, where he advises students, faculty, and staff members on ethical and existential concerns from a humanist perspective. He was TechCrunch's first “ethicist in residence” and has been called “a symbol of the transition in how Americans relate to organized religion” (The Conversation). He is also the author of the New York Times-bestselling book Good Without God.

When we speak about the future of the universe, we mean when the sun burns out, when galaxies collide, when everything flies apart and ultimately evaporates. Do the untold billions and trillions of years from now make it irrelevant for us today? No. The far far future of the universe conveys meaning now.

Featuring interviews with Martin Rees, Wendy Freedman, Abraham Loeb, Alexander Vilenkin, and Robert Russell.
