Journey to the frontiers of human knowledge with astrophysicist Kelsey Johnson as she explores mind-bending questions about the cosmos. Rather than just celebrating what we know, Johnson delves into the profound mysteries that remain unsolved—from the Big Bang to black holes—and examines how these uncertainties intersect with philosophy, theology, and human understanding. Kelsey Johnson is a professor of astronomy at the University of Virginia, former president of the American Astronomical Society, and founder of the award-winning Dark Skies, Bright Kids program. She has won numerous awards for her research, teaching, and promotion of science literacy. She lives in rural Virginia with her family, including two very large dogs. Her new book is Into the Unknown: The Quest to Understand the Mysteries of the Cosmos. Shermer and Johnson engage in a wide-ranging discussion covering fundamental questions about knowledge, existence, and the nature of our universe. Their conversation spans from the origins of the cosmos and the mysteries of dark matter to the possibilities of alien life and multiple dimensions. They explore philosophical concepts like free will, the mathematical nature of the universe, and the intersection of science with theology.
