  • The Day Gravity QUIT!

    The Day Gravity QUIT!
    2026/02/13
    A conspiracy theory went viral claiming that on August 12th, 2026, Earth will lose gravity for seven seconds. The internet did what the internet does, and millions of people started talking about it. So we decided to take the question seriously — what the if gravity actually clocked out for seven seconds? Let's just say you might want to start shopping for bungee cords now. And maybe a bouncy castle. This episode was inspired by an Instagram post from the now-mysteriously-vanished user Mr. Donya OF, where all great science begins. --- Find out more about Gaby's science fiction short story!

  • GROUND HOG Day PHYSICS!

    GROUND HOG Day PHYSICS!
    2026/02/05
    What the if a groundhog could actually predict the weather? Turns out Punxsutawney Phil would need way more than a shadow — we're talking a full groundhog space program, weather satellites, underground supercomputers, and a solar shade the size of western Pennsylvania. Welcome to the groundhog deep state, where fuzzy bureaucrats run atmospheric circulation models and control whether the sun shines on command. And here's the kicker — the whole setup might actually teach you why the weather forecast on your phone is one of civilization's most underappreciated miracles. --- Check out our membership rewards!

  • CITIZEN Science -- with Kirby Runyon!

    CITIZEN Science -- with Kirby Runyon!
    2026/01/16
    Planetary geologist Kirby Runyon from the Planetary Science Institute needs volunteers to map ancient impact melt flows on the moon from their home computers. What the if this went mainstream? Imagine science bars replacing sports bars, Twitch streams of competitive boulder counting, and reality TV dating shows where the best crater mapper wins. We explore a world where professional citizen scientists have mouse sponsorships and your doom-scrolling feed is full of discoveries instead of drama. Plus: the science of molten rock waterfalls and mountains that grew in minutes. Ready to become a citizen scientist? Here's how to get started: Join Kirby's project and start mapping boulders, craters, and ancient lava flows on the moon from your couch — mappers.psi.edu Explore more citizen science projects where you can help map Mars, Mercury, and beyond, plus space podcasts hosted by Kirby's colleague Pamela Gay — cosmoquest.org Learn about the Planetary Science Institute, the nonprofit where Kirby conducts NASA-funded research on Solar System exploration — psi.edu Become a Planetary Partner and support Kirby and his colleagues as they advance world-class research and grassroots science outreach — psi.edu/planetary-partners -------- REVIEW the show: itunes.apple.com/podcast/id1250517051?mt=2&ls=1 SUBSCRIBE for free: pod.link/1250517051 EINSTEIN'S WAR by our very own MATT STANLEY is on sale now!

  • Walking on IO with Robin Andrews! (Encore)

    Walking on IO with Robin Andrews! (Encore)
    2026/01/08
    We're taking a break this week while Philip recovers from the 'double-whammy' of flu and COVID boosters. (Science works, but sometimes it makes you nap!) However, we couldn't let January 7th pass unnoticed. On this day in 1610, Galileo first spotted Jupiter's moon, Io. To celebrate, we’ve unlocked the vault for an encore of one of our most popular episodes ever. Strap in for a tour of a lava-covered world with Robin Andrews in... "Walking on IO". ---- DR. ROBIN GEORGE ANDREWS, science writer for The NY Times, National Geographic, Scientific American, and many more, joins us with an IF that'll keep you on your feet: What The IF we could walk on Jupiter's ultra volcanic moon, IO? Would you walk on a hot pizza? If so, you're ready for the trip! The views of Jupiter would be spectacular, but bring your kevlar umbrella because lava's gonna come flyin' out of the sky. One of the most spectacular places in the solar system, Io is also terribly mysterious, bizarre, and confusing to even the greatest scientists of our time. Pack your bags, bring some galoshes, and let's go! --- Robin Andrews is a doctor of experimental volcanology, a full-time freelance science journalist, a part-time photographer, a scientific consultant, an occasional lecturer, public speaker and explain-how-volcanoes-work TV guest, as well as a pending author of a rather curious book. He can tell you exactly how powerful the Death Star is, how cryovolcanoes on alien worlds work, why a supervolcano probably isn’t what you think it is, and why the Moon is shrinking. His work has appeared in THE NEW YORK TIMES, THE ATLANTIC, NATIONAL GEOGRAPHIC, SCIENTIFIC AMERICAN, EARTHER, GIZMODO, FORBES, THE VERGE, ATLAS OBSCURA, DISCOVER MAGAZINE, WIRED and elsewhere.

  • BIOLOGICAL New Year's Resolutions!

    BIOLOGICAL New Year's Resolutions!
    2025/12/30
    What the if your New Year's resolution became a biological compulsion you literally could not ignore? Imagine waking up on January 1st with the same unstoppable urge that drives salmon to swim upstream, except instead of spawning, you absolutely must get to the gym three times a week. In this world, the darkness of winter triggers something deep in our ancient brain, locking us into whatever commitment we scribbled down at midnight. You'd have to rules-lawyer your own resolutions like a contract with a malicious genie. Society would develop rituals around helping eight-year-olds avoid accidentally resolving to rule the world. Plus, discover a surprising new theory about why Stonehenge exists that has everything to do with cabin fever and nothing to do with astronomy. --- Find out more about Gaby's science fiction short story!

    Time REVERSAL with Ian Durham!
    2025/12/26
    What the if time suddenly started running backwards? Your breakfast un-eats itself, LEGO sets come pre-assembled, and you get younger every day. The dead have unfunerals, your room cleans itself, and teenagers slowly regress through middle school—backwards. Professor Ian Durham of Saint Anselm College stops by to explain the real physics behind time reversal and why photons might start shooting out of your eyeballs. Want to see time reversal in action? Check out The Palindrome Paradox, the mind-bending short film Ian recommends: https://youtu.be/hUcXGv-NzFQ?si=X086RFpXEj0ZNJmX Explore more physics at the Foundational Questions Institute—Ian's top 5 physics stories for 2025 will be out in a week or two on the FQxI Podcast Series: https://qspace.fqxi.org/podcasts And check out FQxI Master Classes, where Ian's course on the nature of time will be out within the year: https://qspace.fqxi.org/qac --- Find out more about Gaby's science fiction short story!

  • Santa's MEGA Fauna!

    Santa's MEGA Fauna!
    2025/12/20
    Listener Anne of Queens got us thinking about flying reindeer for the holidays. Imagine herds of 1,500-pound mammals migrating through your town like Canada geese. Suddenly those goose droppings don't seem so bad. Discover why the classic Santa sleigh makes no aerodynamic sense (eight reindeer in parallel? Your cargo's dragging on the ground) and why the real solution is a reindeer dirigible with forty hovering reindeer and a sleigh dangling underneath. Watch Santa relocate from the North Pole to a Sri Lankan mountaintop, where his reindeer have evolved big fennec-fox ears to vent heat in the tropics. Strap on your hard hat and join us for a holiday flight. --- Find out more about Gaby's science fiction short story! Here are the links for the anthology.
