Mario Livio on Galileo, Science Denial, and the Future of the Universe

How can we measure the universe—and determine what it is made of? Nobel Prize-winning astrophysicist George Smoot joins Robert Lawrence Kuhn to explore precision cosmology, from measurements of the cosmic microwave background to dark matter, dark energy, and the expansion of the universe. They discuss how gravitational lensing is becoming an increasingly powerful tool for probing the cosmos and investigating what dark matter might actually be. Smoot also looks ahead to new observations and technologies that could help answer some of cosmology’s biggest remaining questions.

What might humanity look like decades, millennia—or even millions of years—from now? Science-fiction author and futurist David Brin joins Robert Lawrence Kuhn to explore humanity’s possible futures. They discuss artificial intelligence, genetic engineering, nanotechnology, space exploration, alien civilizations and the Fermi paradox, as well as consciousness, the nature of truth, and whether there is any deeper meaning to human existence. Brin considers both the existential risks humanity faces and the possibilities that could emerge if civilization survives and continues to develop.

Could a single theory explain the fundamental workings of the universe? Theoretical physicist Michio Kaku joins Robert Lawrence Kuhn to discuss The God Equation and the quest for a Theory of Everything. They explore string theory, the multiverse, higher dimensions, time travel, the Big Bang, and what a final theory might reveal about reality and our place in the cosmos. This conversation was originally recorded following the publication of Kaku’s The God Equation: The Quest for a Theory of Everything.

Can your theory of consciousness determine your answers to the biggest questions in philosophy, science, and religion — AI sentience, life after death, free will, personal identity? Robert Lawrence Kuhn presents his landmark taxonomy of consciousness theories — spanning materialism, quantum theories, information, panpsychism, dualism, idealism, and more — and argues that every serious question about mind and perhaps even about existence depends on which theory you hold. Recorded at the 7th Woodenfish Forum on Buddhism, Science & Future ("Rewriting Reincarnation in the Light of Frontier Biotechnology"), held at The Grand Hotel, Taipei, June 5–7, 2026, and introduced by the forum's founder, Venerable Dr. Yifa. Robert Lawrence Kuhn is the creator, producer, writer, and host of _Closer To Truth,_ the long-running PBS series and global resource on cosmos, consciousness, and meaning. He holds a PhD in anatomy and brain research from UCLA and is the author of "A Landscape of Consciousness: Toward a Taxonomy of Explanations and Implications," editor-in-chief of the Landscape of Consciousness website, which currently catalogues nearly 450 theories of consciousness. The Landscape of Consciousness website: https://loc.closertotruth.com/ Venerable Dr. Yifa is the founder and director of the Woodenfish Foundation, an international, nonsectarian nonprofit dedicated to building a global network of ethical and compassionate leaders. A Yale-educated Buddhist nun and Associate at the Harvard University Asia Center, she has appeared on Closer To Truth exploring Buddhist philosophy. The Woodenfish Forum on Buddhism, Science & Future was founded by Venerable Dr. Yifa with the aspiration of engaging Buddhist thought through the lens of scientific inquiry. The 2026 forum brought together leading scientists, philosophers, and religious thinkers to explore reincarnation, consciousness, and the ethics of frontier biotechnology.

Is there more than one universe? According to current cosmology, our entire gigantic universe is only one of innumerable universes, each universe like one tiny bubble in a limitless ocean of universes. What could all this mean? Featuring interviews with Max Tegmark, Anthony Aguirre, Alan Guth, Andrei Linde, and Paul Davies.

What is “nothing”? What does it mean for nothing to exist—or for nothing to have ever existed? In this episode, Robert Lawrence Kuhn explores one of philosophy’s deepest questions: Why is there something rather than nothing? Through conversations with philosophers and physicists, the discussion examines the nature of nothingness, whether absolute nothing is possible, and how different philosophical and scientific perspectives attempt to explain the existence of the universe. Featuring Richard Swinburne, Simon Blackburn, Robert Spitzer, Peter van Inwagen, Steven Weinberg, John Leslie, Timothy O’Connor, Victor Stenger, John Hawthorne, and Peter Forrest.

What can Galileo still teach us about science, truth, and discovery? In this conversation, Mario Livio discusses Galileo’s scientific legacy, the Hubble Space Telescope, science denial, exoplanets, cosmology, and the future of life in the universe. Drawing from his book Galileo: And the Science Deniers, Livio explores Galileo’s role in the development of the scientific method and examines how scientific understanding evolves through observation, experimentation, and self-correction. Mario Livio is an astrophysicist and author who worked for 24 years at the Space Telescope Science Institute, which operates the Hubble Space Telescope.
