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.

Michael Shermer interviews Jon Mills, a psychoanalyst and philosopher, on a variety of topics, including the evolution of psychoanalysis, the dynamics of therapeutic relationships, and the psychological roots of aggression and trauma. Mills explains Freud’s lasting influence, the moral implications of aggression, and the role violence plays in society. The conversation also explores how trauma affects individuals and families across generations and the difficulty of understanding human behavior when faced with global challenges.

The discussion extends to broader issues such as individuality, the struggles faced by modern youth, and the evolution of belief in God. Shermer and Mills discuss how technology impacts mental health and the pursuit of spirituality without relying on traditional religion.

Jon Mills, PsyD, PhD, ABPP, is a philosopher, psychoanalyst, and clinical psychologist. His two latest books are Inventing God: Psychology of Belief and the Rise of Secular Spirituality, and End of the World: Civilization and its Fate.

In this special solo episode, Michael Shermer reflects on the 2024 election.
