NOVA Presents

Hakeem says there was more than one big bang. There were ten.

Our host answers the biggest questions about his latest book, Why Do We Exist? Like, how the idea of ‘now’ depends on your relative motion or that there might be a time before time. Reality keeps unravelling as he explains that at a certain distance space recedes even faster than light. To top it off, the conversation enters the Realm of Imagination, and joins Hakeem in his optimistic view of human space travel, world peace, and even the apocalypse.

Hakeem has hot takes on space. For instance, the moon is a planet.

In Hakeem’s new book, Why Do We Exist?, he shares big ideas about the universe. Why do so many stars come in pairs? How likely is extraterrestrial life? What if there was no friction? Hakeem challenges us to think like him and see our reality through his Nine Realms of the Universe. Through that lens, atoms model galaxies, stars take new names, and the statistically improbable becomes more likely over time. Settle in for a conversation between Hakeem’s mind and the heavens.

Our host flips the interview and shares his humble beginnings before science superstardom.

Hakeem opens up about a childhood moving between some of America's toughest neighborhoods, surviving drugs, and overcoming addiction. Luckily, an encyclopedia article on Einstein changed everything and set him on his unlikely path from rural Mississippi to Stanford. Along the way, he changed his name, found some key mentors, and became an astrophysicist, but more importantly, Hakeem started a journey to bring science to millions

Earthquakes can be more powerful than atomic bombs.

Luckily, Harvard geophysicist John Shaw has ideas on how to beat them. What really causes earthquakes? How can cities and buildings be engineered to survive them? John and Hakeem trace the science of shaking ground from ancient myth to cutting-edge machine learning, and reveal just how much is still left to discover deep beneath the surface.

Big earthquakes can change the Earth’s rotation.

And Harvard geophysicist John Shaw says these giant events can teach us a lot. He traces our understanding from ancient myths to modern studies and unpacks what;s really going on beneath the surface. John reveals why a magnitude 7 earthquake releases 30 times the energy of a WWII-era atomic bomb, how the largest quakes make the Earth ring like a bell for days, and why the deadliest earthquake in history wasn't even the biggest one.

There is a near-limitless energy source to power our world, and it may be almost here.

Dennis Whyte shares with Hakeem that we're closer than ever to bottling the power of the sun. He would know. He’s now the CEO of the United Kingdom’s Atomic Energy Authority and a nuclear scientist at MIT. What happens when we finally unlock nuclear fusion, the same energy source that powers the sun? What even is fusion? How does it work, and why are scientists now so close to building commercially viable fusion systems that could put power on the grid? From fusion fundamentals, to the future of energy, to interstellar space travel, Dennis and Hakeem deliver a big conversation on an innovation that could change everything.

Federico Rossano convinces Hakeem that animals have a lot more to say than we've given them credit for. The cognitive scientist shares the origin story behind his record-breaking study of talking dogs, the evidence that some pets may understand more than a human toddler, and what primates reveal about the roots of communication itself.

Federico Rossano is an Associate Professor of Cognitive Science at UC San Diego and director of the Comparative Cognition Lab, where he studies communication and social cognition across humans, primates, dogs, and cats. He leads the world's largest study of button-trained pets, and his research is featured in the NOVA documentary Can Dogs Talk?

Federico Rossano says the secret to speaking with apes is trust. For primates, the world is full of high-stakes friends and foes, and of course, there are always predators to worry about. Our closest relatives see the world a little differently than we do, and that can teach us a lot about our own communication. Federico is a cognitive scientist who questions the assumptions beneath human conversations, and in this episode, he shares lessons from the animal kingdom with Hakeem. From apes besting children in “the peanut puzzle” to baboons that seemingly sense how to travel together, there’s lots to learn.

Federico Rossano caught dogs doing something that looks a lot like telling jokes. The cognitive scientist shares what he learned from speaking with dogs. Dogs can smell, hear, and in some ways see better than humans. So why wouldn’t they have something interesting to say if they could speak? Federico has found a dog's mind may be closer to a human toddler's than anyone previously believed and believes we are close to learning important lessons from our canine companions.

Brent Minchew could have a plan to stop Thwaites Glacier, AKA the “Doomsday Glacier”, cold in its tracks. That’s good news because if this one glacier slips into the sea, it could flood coasts across the planet. The Caltech glaciologist covers what makes the “Doomsday Glacier” the single biggest wild card in sea level rise, the simple idea that could freeze it back to its bed, and his own improbable journey from 9/11 first responder to two of the world's top science institutions. It's a conversation about glaciers, courage, and what it takes to change the story.

Brent Minchew is an expert on the glacier that could devastate the world’s coastlines. As a glaciologist at Caltech, he's spent his career tracking Thwaites Glacier, AKA the "Doomsday Glacier." It’s roughly the size of Florida and already losing 50 billion tons of ice a year. Brent joins Hakeem to break down what scientists know – and don’t know – about the glacier that could determine our future. How certain is that “doom,” and how fast could it happen? They nerd out about what happens as glaciers slip into the sea, how satellites can measure glacier movement down to the millimeter from orbit, and how Thwaites might be the single most important glacier on the planet.

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 universe. From new dimensions to hurricanes we can't quite predict, Jordan and Hakeem trace math's fingerprints across physics, language, and daily life in a preview of his upcoming book, Don't Be Too Sure.
