Exploring the Deep Mysteries of Physics | World Science Festival

Are the laws of physics real, or are they human inventions? This is one of many questions Brian Greene and Sean Carroll explore at the very edge of understanding, where physics meets philosophy. Carroll, a theoretical physicist at Johns Hopkins University, host of the Mindscape podcast, and a bestselling author, joins Greene for a wide-ranging conversation regarding the workings of the world at its deepest level. Is mathematics discovered or invented? Why is there something rather than nothing? Do we have free will, and could an AI ever be conscious? Carroll makes his case for the Many Worlds theory of quantum mechanics, explains why he believes the other worlds genuinely exist, and defends the dramatic claim that the universe may be fully described by a quantum state in Hilbert space. They close with the surprising mathematical patterns connecting all mammals, and whether artificial intelligence will transform physics research itself. This program is part of the Rethinking Reality series, supported by the John Templeton Foundation. #QuantumMechanics #SeanCarroll #PhysicsAndPhilosophy #ManyWorlds #FoundationsOfPhysics Participant: Sean Carroll Moderator: Brian Greene Don't miss a video!

ABOUT WORLD SCIENCE FESTIVAL: The World Science Festival (WSF) is a multimedia organization bringing the most transformative ideas in science to global audiences. Through long- and short-form videos spanning physics, cosmology, quantum mechanics, biology, neuroscience, consciousness, medicine, space exploration, the dilemma of free will, artificial intelligence, engineering, robotics, and beyond. WSF gathers world-renowned scientists, artists, and thinkers for dynamic discussions, debates, lectures, performances, films, and immersive live experiences. Founded in 2008 and headquartered in New York City, the World Science Festival is a production of the World Science Foundation, a 501(c)(3) nonprofit organization. Our mission is to cultivate a public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future. With live events reaching millions worldwide and hundreds of millions of digital views, WSF continues to expand its global impact through festivals, educational initiatives like World Science U, and digital content that explores the near and far future of our world.
