Cosmic Queries - Proving Einstein Right
Neil deGrasse Tyson and co-host Chuck Nice speak with theoretical physicist Jim Gates about Albert Einstein's special and general relativity, why general relativity required experimental verification, and the 20th‑century efforts to test it via starlight deflection during a solar eclipse. They then field listener questions on topics including the incompatibility between general relativity and quantum mechanics, gravitons and quantum gravity, string theory signatures in the cosmic microwave background, gravitational lensing, and the possibility of a cosmic gravitational-wave background. Throughout, Gates also reflects on the "magic" of mathematics in describing reality and the collaborative, human side of doing physics.
Things You Thought You Knew - Force, Heat, & Speed
Neil deGrasse Tyson, joined by comedian co-host Chuck, explores three commonly confused physics pairs: force versus pressure, heat versus temperature, and speed versus acceleration. Using everyday examples like gym spotting, walking on ice, kitchen knives, tornado damage, ocean warming, air conditioners, and sports cars, he shows how precise definitions change how we understand real-world phenomena. The conversation emphasizes how these distinctions explain everything from why houses explode in tornadoes to why Teslas feel so fast and why the ocean can store vast amounts of heat.
Quantum Refuge
Radiolab host Lulu speaks with 28-year-old Gazan physicist Qasem Walid about how quantum physics has become both a language and an inner refuge for him while living through war, displacement, and loss in Gaza. Over months of conversations, he describes daily life under bombardment, the deaths of his professor and relatives, and his experience of feeling like Schrödinger's cat-trapped in a box where his survival is uncertain and unseen by the outside world. He uses concepts like superposition, quantum tunneling, and harmonic oscillators to make sense of his own existence and to plead for the world to "open the box" and truly look at what is happening in Gaza.
The Limits of Knowing with Elise Crull
Neil deGrasse Tyson and co-host Chuck Nice talk with philosopher of physics Elise Crull about the historical and contemporary relationship between physics and philosophy. They trace how natural philosophy split into specialized disciplines, how foundational concepts like space, time, and objectivity shaped classical and modern physics, and why questions raised by quantum mechanics-such as entanglement and non-locality-force a reevaluation of those concepts. The conversation also explores academic specialization, the role of philosophy in guiding cutting-edge physics, and Neil's nuanced critique of modern academic philosophy.
The Science of Godzilla, Zombies & Other Monsters, with Charles Liu
Neil deGrasse Tyson, co-host Matt Kirshen, and astrophysicist Charles Liu explore the science and cultural meaning of monsters, from Godzilla, dragons, King Kong, and Frankenstein to zombies and black holes. They discuss how physics, biology, and scaling laws constrain what monsters could exist, and how stories about monsters reflect human fears, technological change, and environmental anxieties. Throughout, they argue that the real "monsters" are often human hubris and ignorance, and that science can both demystify and reframe these fears.
Things You Thought You Knew - Quantum Cat
Neil deGrasse Tyson and co-host Chuck Nice explore three classic concepts from astrophysics and quantum physics: death by black hole, Schrödinger's cat and the observer effect, and quantum tunneling. They explain tidal forces and spaghettification near black holes, clarify what the quantum observer effect really means, unpack the idea of superposition in Schrödinger's cat and qubits in quantum computing, and show how quantum tunneling enables nuclear fusion inside stars at temperatures lower than classical physics would predict.
