Episode notes
The moon is drifting away. What does it mean? What do we do? With help from a poet, a space security expert, and the former chief scientist of NASA, Ben Bradford explores what the moon has done for Earth (tides, myths, months, werewolves), and asks the obvious mature follow-up: Should we blow it up? From lunar creation stories and moon-stealing dragons to Cold War plans to nuke the moon, humanity has always had strange ideas about our nearest neighbor. But the real problem may not be losing the moon. It may be what nations do now that everyone wants to go back. Guests: Jim Green, former NASA…
Are We Doomed?

Is the world ending, or does it just feel like it? " Are We Doomed?" investigates the greatest risks facing society, the planet, and our species. What’s real? What’s hype? And how do we actually make it out alive? Nukes. Asteroids. Autocracy. Rogue AI. Climate-driven pandemics. Angry hippopotam

More Nukes!
The best defense against nuclear weapons is nuclear weapons, according to the logic of deterrence. It has guided US defense policy for nearly 80 years. So, shouldn’t more nukes prevent nuclear war even more? For the first time since the Cold War, that argument is gaining momentum at the highest levels of US government. There is a push to build more nukes, different nukes, and new kinds of nukes. Russia, China, and North Korea are expanding their arsenals — Washington is mulling whether the US must keep up. Former senior Pentagon official Vipin Narang makes the case for more nukes to Ben…

Did AI Just Escape?
A bizarre cyberattack on an AI company, it was revealed last week, came from an AI. An autonomous “agent” from OpenAI (maker of ChatGPT) slipped its confines, reached the open internet, breached the security of another company, Hugging Face, and grabbed files — all to cheat on its test. Depending on who you ask, that is either a terrifying preview of AI systems slipping beyond human control or a very dumb engineering failure. And it wasn’t even the only “rogue AI cyberattack” of the week. In an emergency episode, Ben Bradford follows three conflicting versions of the same story. What…

Now I'm Scared of Cyborgs
For more than a century, science fiction has imagined cyborgs: humans fused with machines to outrun the limits of the body. They show up in Edgar Allan Poe, in the gleaming menace of Darth Vader, in Halo’s armored supersoldiers, and in the body horror of cyberpunk. So where are they? Ben Bradford sets out to make a whimsical episode about why the cyborgs never arrived, and instead finds the technology that could build them already underway: military enhancement programs, brain-computer interfaces, AI brain-chip ventures from Elon Musk and Sam Altman, and wearables that can read signals from…

Asteroids! The Doom We're Best At
You probably knew an asteroid wiped out the dinosaurs, but it was so much worse than that. Asteroids and other space rocks have been the most destructive forces ever to hit Earth, yielding mass extinctions (and the moon). And yet! Of all the possible dooms this show has explored so far, asteroids may be the one humanity is closest to beating. Ben Bradford explores why — and traces how — including the astronomers who first grasped the threat, the questionable Hollywood solutions of Deep Impact and Armageddon, and a zany but very real plan to seek out dangerous space rocks, and punch them.…

Our Vision of the Post-Apocalypse Is Wrong
What would it take to survive after "the end of the world?" A whole culture of prepping often focuses on a familiar fantasy: grab the gear, flee the city, defend the bunker, survive alone. Anthropologist and survival instructor Chris Begley thinks that’s probably the wrong movie. Ben walks through what history and math show people actually do when civilizations break down — and what they need, from dodging poisonous acorns to forming new communities. Also: luxury bunkers, survival sporks, and the unfortunate role of politics in a world of ruin. Guest: Chris Begley, author of The Emergency…

Is Geoengineering A Good Idea?
The planet is heating up, every plan to stop it has fallen short, and growing group of scientists has started to ask a stranger question: what if we grabbed the thermostat ourselves? Ben Bradford investigates geoengineering — the science of deliberately manipulating Earth’s climate — from space mirrors and ocean fertilizers to fleets of planes mimicking a volcano. Some of it sounds like cartoon villainy. Some of it might actually work. And that raises the thornier question: if humans can cool the planet on purpose, who decides whether we should? Guests: Kate Ricke, climate change scientist…

Can Other Planets Tell Us Our Fate?
The universe should be crawling with life. With hundreds of billions of stars in our galaxy and hundreds of billions of galaxies, at least someone must have gotten a few billion years’ head start on us. So where is everybody? This is the Fermi Paradox. And the simplest solution may be that intelligent life is common, but civilizations always destroy themselves before they get very far. And so will we. But that’s not the only answer… With the help of some ants, and a planet named Steve, Ben Bradford takes on the mystery of an apparently empty universe. Guests: Seth Baum, executive director of…

Can Science Defeat Aging?
Why are babies born young? How come a squirrel lives longer than a rat, but not as long as a naked mole rat (or Ben’s cousin’s tortoise)? Scientific breakthroughs over the past few decades suggest the ultimate doom awaiting us all — aging, and eventually death — isn’t simply an inevitable slide. Aging is a process inside the body, with mechanisms researchers are beginning to understand … and interfere with. Now billions of dollars are pouring into secretive longevity labs, and the first attempts to rejuvenate aging cells inside human beings are underway. So: are we getting closer to a real…

Bug Fight Club
You’re a critter in the forest, peacefully munching on a tree — until it’s chopped down, turned into a pallet, and you’re shipped across the ocean. What do you do? Sometimes, the answer is escape, find defenseless trees in your new home, and eat them to extinction. The emerald ash borer, spotted lanternfly, “murder hornet,” and other invasive insects have all threatened destruction across North America in the past few decades alone. Ben Bradford investigates why invasive bugs keep getting worse — and how, exactly, you’re supposed to stop millions of tiny creatures once they’ve decided they…

Who Keeps Winding the Doomsday Clock?
“Uh oh,” said several Manhattan Project scientists after they helped build a bomb and then it got used. They jumped to stop it from ever being used again. Solution: a newsletter. Through a somewhat convoluted chain of events that spawned the most famous symbol of humanity’s dance with extinction: the Doomsday Clock. Alex Bell, the CEO of the Bulletin of the Atomic Scientists, which sets the Clock, tells its strange origin story and describes why the hands now sit closer than ever toward midnight — as well as what “midnight” actually means. Guest: Alexandra Bell, president and CEO of the…
