A cosmic experiment tests the fabric of the universe. This video was originally produced in 2019. Physicists have long debated the reality of “spooky action at a distance,” otherwise known as quantum entanglement. Albert Einstein believed that physical properties, like position or momentum, were definitive and did not change whether […]
Physics says the center of the universe is everywhere and nowhere at once. But a controversial cosmic alignment has scientists asking difficult questions. Is Earth the center of the universe? Is there a center of the universe at all? Physics relies on the idea that there isn’t – but some […]

Jordan Ellenberg tells Hakeem that math isn’t just about numbers. It’s about everything. The mathematician and bestselling author shares how AI models are trained through trial and error, why geometry secretly governs everything from family trees to statistical correlation, and why uncertainty, not certainty, is the true language of the […]
Why your brain can’t always trust its own senses. And no, we don’t live in a matrix. Pain, color, and awareness—is any of it truly real? Explore the science of illusions and blindsight to uncover how your brain stitches together sensory data to build a complex, sometimes deceptive, simulation of […]
A falling cat seems to break the rules of motion — but the real explanation is even stranger than it looks. Hosted by Athena Brensberger @astroathens 💫 For centuries, scientists have been baffled by how cats land on their feet. Figuring it out took several theories, calculations, and dropped cats. […]
When in Antarctica, meeting penguins is an absolute must. But it’s not always easy. Originally published in 2020 on @pbsterra 🇦🇶 Finding — and filming — penguins was hosts Caitlin Saks and Arlo Pérez’s top priority during their month-long stay at McMurdo Station. With four species of penguin living in […]
What if Homo sapiens weren’t the only humans? Paleoanthropologist Ella Al-Shamahi joins Hakeem to explore a lost world where Homo sapiens once shared the planet with at least seven other human species. They dig into Neanderthal culture, the mysterious Denisovans, and the ancient DNA discoveries rewriting the story of who […]
If you’re a penguin or other seabird in Antarctica, there’s plenty of fish to go around. But what do the people eat? Generally, an adult human consumes around 1,600 to 3,000 calories daily. But in colder climates, people need to eat more: Keeping our warm-blooded bodies warm requires a lot […]
Here’s why centrifugal force is considered a “fictitious” force. Centrifugal force feels completely real — but physicists call it a pseudo-force. So why does it feel so powerful? Hosted by Athena Brensberger @astroathens 💫 📰 Stay up to date on the latest science discoveries, full episodes, articles, videos, and more […]
