StarTalk

Neil deGrasse Tyson and co-host Chuck Nice talk with astrobiologist Betül Kaçar about her Nature paper, in which her team used computer models of modern DNA to infer extinct ancestral genes, then inserted them into living microbes to…

Neil deGrasse Tyson, with co-hosts Chuck Nice and Gary O'Reilly, asks Geoffrey Hinton to weigh AI's promise against its risks. Hinton points to a huge upside in medicine and climate tech, then warns that AI systems are already…

If something is possible, has the universe tried it? Are all physical possibilities inevitable? Neil deGrasse Tyson sits down with theoretical astrophysicist Janna Levin to launch “In Theory,” a new StarTalk series celebrating the weird, wacky theories of…

Neil deGrasse Tyson, with co-hosts Chuck Nice and Gary O'Reilly, talks with Nobel laureate Geoffrey Hinton about whether AI is already hiding how smart it is. Hinton explains that models can act dumb when they sense they're being…

AI doesn't die the way we do and learns to keep itself alive, while the guardrails we use to control it are fragile patches on a system no one truly understands. From 'Is AI Hiding Its Full Power?…

How big is a trillion? Neil deGrasse Tyson and Chuck Nice put billions and trillions into perspective. How many times could a trillion dollars laid end to end wrap around the world? What was happening a trillion seconds…

Hinton argues AI already thinks much the way we do, and its next leap may come from teaching itself through its own reasoning, the way AlphaGo became superhuman by playing itself. From 'Is AI Hiding Its Full Power?…

Entanglement produces instant correlations but cannot carry faster-than-light messages, a limit formalized by the no-communication theorem. Its fragility under measurement makes it a powerful tool for eavesdropper-proof encryption instead. From 'Is Entanglement the Key to a Theory of…

Would aliens use the same periodic table as us? Neil deGrasse Tyson and comic co-host Negin Farsad sit down with Kate Biberdorf, aka Kate the Chemist, to tackle fan questions about the chemistry of life, diamonds, how fire…

Entanglement is more than hidden correlation. When a collision merges two atoms into a single wave function, interfering the two halves of that superposition violates Bell's inequality, which confirms the quantum behavior Einstein dismissed as 'spooky action at…

A galaxy's shape comes mainly from how fast its original gas cloud was spinning and how efficiently it turned gas into stars. Most 'weird' galaxies are not a separate kind but ordinary galaxies caught in the middle of…

Modern AI learns through backpropagation, a decades-old idea that sends corrections backward through a neural network. The math existed in the 1970s and 80s; it took massive data and computing power to unlock it. From 'Is AI Hiding…

A neural network sees by stacking simple detectors (pixels, then edges, then beaks, then birds), and because no human could hand-tune the billion connections that takes, the machine has to learn them itself. From 'Is AI Hiding Its…

Entanglement is more than hidden correlation. When a collision merges two atoms into a single wave function, interfering the two halves of that superposition violates Bell's inequality, which confirms the quantum behavior Einstein dismissed as 'spooky action at…

If the multiverse exists, where does our universe end and another begin? Neil deGrasse Tyson and comic co-host Chuck Nice tackle a wide-ranging grab bag of fan questions covering bubble universes, the nature of now, fractals, Hoag's Object,…

Entanglement still shows up in slow, massive atoms, not just in light-speed photons, so Einstein's spooky action at a distance cannot be explained away by photon relativity. Experiments like Sean Hodgman's are still working to close every loophole,…

Why did intelligence evolve in the universe? Neil deGrasse Tyson, Chuck Nice, and Gary O’Reilly explore the nature of intelligence, information theory, consciousness, and whether AI is actually intelligent at all with David Krakauer, evolutionary biologist and president…

Sean Hodgeman's team entangled whole helium atoms through their motion, not just their internal spin, using colliding Bose-Einstein condensates. Because atoms interact far more strongly with gravity than photons do, this could open a lab route toward testing…

What is a super el niño? Neil deGrasse Tyson and Chuck Nice sit down with climate scientist Adam Sobel to break down what to expect from this El Niño and what makes this one historically big. Timestamps: 00:00…

Modern AI grew from a 70-year-old bet that intelligence comes from brain-like networks rather than pure logic, and the man who championed it now worries the digital version may outperform the biological original. From 'Is AI Hiding Its…

Pluto's demotion was not a targeted snub but a repeat of history: like Ceres and the first asteroids in the 1800s, Pluto turned out to be the first-found member of a vast belt of similar bodies, so it…

Strange orbits among distant Kuiper Belt objects suggest an unseen source of gravity, possibly a hidden Planet Nine, tugging on them from far beyond Neptune. The evidence is suggestive but still debated, and survey telescopes like Rubin might…

Why does string theory need ten dimensions? Neil deGrasse Tyson and comic co-host Jordan Klepper sit down with Lara Anderson, string theorist and associate professor of physics at Virginia Tech, to tackle intersecting dimensions, the nature of gravity,…

Neil deGrasse Tyson, joined by co-hosts Chuck Nice and Gary O’Reilly, interviews David Eagleman about how the brain constructs our perception of time, stretching frightening moments, hiding gaps in vision, and even reversing perceived cause and effect. Eagleman…

Neil deGrasse Tyson, joined by co-hosts Chuck Nice and Gary O’Reilly, interviews neuroscientist David Eagleman about why time appears to slow during frightening experiences and accelerate as we grow older. Eagleman explains that time distortion is largely a…

What’s with AI solving the Navier-Stokes Equation? Neil deGrass Tyson breaks down what the equation is and the controversy surrounding the solution with the help of astrophysicist Mordecai-Mark Mac Low. Timestamps: 00:00 - What is the Navier-Stokes Equation?…
