  Why Your Body Needs Gravity 13.09.2026 43p

  Does space travel make astronauts younger? Professor Hannah Fry and Michael Stevens explore Einstein’s twin paradox, time dilation and NASA’s famous Twins Study with astronauts Scott and Mark Kelly. After Scott Kelly spent 340 days aboard the International Space Station, he returned milliseconds younger than his identical twin. But microgravity had also affected his eyesight, bones, blood, gut microbiome, body temperature, genes and telomeres. So what exactly happens to the human body in space, and which changes remain after astronauts return to Earth? In this episode, Hannah and Michael discover how deeply the human body depends on gravity. Along the way, they uncover why your head ages faster than your feet, what a 63 day cave experiment reveals about our sense of time, and whether future humans could ever truly adapt to life beyond Earth. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  The Scale of the Universe 02.09.2026 49p

  The scale of the universe stretches from the Planck length, the smallest scale physics can describe, to the observable universe, the largest thing we can see. Travel inward from one and outward from the other by powers of ten and they meet at something astonishingly familiar: the size of a human egg cell. Michael Stevens (VSauce) takes Professor Hannah Fry on a journey through powers of ten, from quarks and protons and DNA to bananas and pyramids and on to planets and galaxies, to explore where we sit in the scale of the universe. Along the way they ask whether the Planck length could be the universe's smallest pixel, whether reality might be a computer simulation and just how empty space really is.

  Why Loud Chewing Makes You Angry 30.08.2026 49p

  The mukbang phenomenon is comfort viewing for millions, yet for others the sound of chewing, slurping and everyday mouth noises is enough to trigger instant anger, disgust and distress. Why do the sounds soothe one person and enrage another? In this episode, Professor Hannah Fry and Michael Stevens (Vsauce) explore misophonia, the misunderstood sound sensitivity that can turn everyday mouth sounds into powerful emotional triggers. 1 in 5 people in a UK study have reported a hatred of mouth sounds, but where does the problem lie, and can you train your brain to stop hating a sound, or is the person chewing next to you simply beyond forgiveness? Are the sounds themselves the trigger? Or is the structure of the human ear to blame? Perhaps, instead, the answer lies in a surprising connection between our brains and our jaws. To find out, Hannah and Michael trial a surprising trick that could offer genuine relief, and discover how changing what you see can completely transform your response to what you hear. Along the way, they investigate nails on blackboards, the frequencies used in acoustic weapons, the device designed to drive teenagers out of public spaces and the curious connection between misophonia, ASMR and the mukbang world itself. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  How Does Language Change What You Smell? 26.08.2026 46p

  In this episode of Field Notes, Professor Hannah Fry and Michael Stevens (Vsauce) begin with a Persian word for a smell Hannah cannot detect on a freshly washed plate. From the Sapir-Whorf hypothesis and Russian words for blue to emotions and identity, Hannah and Michael investigate how language may shape our experience of the world. Then, your questions. How fast would you need to throw a rock for it to escape Earth? What is the planet's escape velocity? Could it survive the atmosphere, or would it take something the size of the Chicxulub asteroid to make it out? How does soap kill germs? Why does bleach feel slippery on your hands? And can a scientific theory be completely wrong but still appear to work? Join them, as they explore linguistics, psychology, colour perception, space travel, bacteria, viruses and, of course, the scientific method. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  Space Elevators, Skyhooks, and Space Fountains 23.08.2026 1ó 5p

  What is the fastest, cheapest and possibly worst way to get into space? Could a nuclear explosion launch a manhole cover beyond the Earth’s atmosphere? And could space elevators, skyhooks or launch loops one day replace rockets? In this episode, Professor Hannah Fry and Michael Stevens (VSauce) explore where space really begins, why orbit means falling forever, and how Newton’s cannon explains the motion of the International Space Station. They also interrogate the physics of the Kármán line, orbital velocity and geostationary orbit, before asking whether humans could ever climb a staircase to space, or catch a rotating skyhook into orbit. Plus, the far future fate of Earth, firing a bullet around the Moon, the true value of the Apollo Moon landing, the ethics of colonising Mars and whether the future of space exploration should belong to private companies or the public! ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  Hannah Ranks Michael's Bizarre Watches 19.08.2026 54p

  Michael Stevens keeps a small museum of unusual timepieces on his desk: a clock that runs backwards, a watch built to be read in complete darkness, and one whose entire face simply says "now." Each is a miniature experiment in the psychology of time, and each reveals something surprising about how our perception of time shapes the way we understand uncertainty and the world around us. The conversation then turns to logic and reasoning: how we make judgements, why we get things wrong, and whether thinking more carefully can help us make better sense of reality. It ends with your questions, including why so many of us are convinced we're simply "not maths people”. Is that belief itself, rather than any innate ability, the real source of our mathematical failure? ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  The Lake At The North Pole That Stops Europe From Freezing 12.08.2026 47p

  When you picture the North Pole, you probably imagine a vast, frozen expanse of floating sea ice. But hidden deep beneath the surface of the Arctic lies something incredible: a massive, churning reservoir of nearly freshwater, suspended right in the middle of a saltwater ocean. In this episode of The Rest Is Science, Professor Hannah Fry and Michael Stevens (VSauce) explore the hidden hydrodynamics of the Arctic. Fresh off a real-world scientific expedition to the sprawling ice sheets of Greenland, Hannah shares firsthand accounts of the colossal forces currently reshaping our polar regions. Together, they unpack the bizarre physics that allow a gigantic freshwater lake to form beneath the Arctic ice.

  The Science of Putting Sunglasses on The Sun 09.08.2026 1ó

  Why does the cartoon Sun always wear sunglasses? And how big would a real pair need to be? Hannah Fry and Michael Stevens investigate space mirrors, Reflect Orbital and solar eclipses to find out. Starting with a pencil held at arm’s length, they use the Sun’s angular diameter to calculate how big a pair of solar sunglasses would need to be for one eye, two eyes, everyone in London and eventually the entire planet. Their hypothetical answer is a strange structure more than a million kilometres wide, positioned deep in space. Entirely practical. They compare its extraordinary scale with NASA’s Parker Solar Probe, the real spacecraft flying closer to the Sun than anything ever built, before using Lagrange points to work out where their creation could possibly go. But could putting something between Earth and the Sun ever be useful? Real proposals for space sunshades and climate geo-engineering suggest that blocking a small fraction of sunlight could help cool the planet. Moving from shade to reflection, they revisit Soviet attempts to reflect sunlight onto Earth at night and explore how Reflect Orbital’s Earendil 1 space mirror experiment might one day extend solar energy beyond daylight hours. That leads them to the strange physics of light itself. Photons can push solar sails despite having no rest mass, revealing why E=mc² is only part of the full energy momentum equation from special relativity. Finally, there is the optical phenomenon known as the Arago spot to contend with. It helps explain why NASA’s starshade concepts, future technology designed for hunting exoplanets, look like enormous sunflowers. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  Why Is It A Colour Wheel & Not A Line? 05.08.2026 47p

  Colour wheel or colour line? Light itself runs in a straight line from red to violet, yet every colour theory chart bends that spectrum into a circle and the reason has nothing to do with physics. Professor Hannah Fry and Michael Stevens (VSauce) dig into why human vision refuses to see colour the way light actually behaves, tracing the visible light spectrum from one end to the other and asking where all the "missing" colours, like magenta and purple, actually come from if they don't exist on that spectrum at all. It turns out the colour wheel is less a description of light and more a diagram of a workaround your brain performs constantly.

  Why Lithium Batteries SUCK 02.08.2026 54p

  Can Hannah convince Michael that the lithium-ion battery is one of our most overrated inventions to ever happen? Hannah makes her case using a surprising energy source hidden in your fridge, a bell in Oxford that's been ringing since 1840, and a metal that is useful… but prone to bursting into flame from the inside out. Tracing the battery's strange history, from a twitching dead frog to the executed man who helped inspire Frankenstein. But the real point runs deeper: we don't have an energy problem, we have a storage issue, and until we crack it, the clean energy future stays just out of reach. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  It Wasn't A Hoax After All 26.07.2026 59p

  Did the world really end in 2012? Not with fire, meteors or an ancient Mayan prophecy, but Professor Hannah Fry and Michael Stevens ask whether something just as profound took place instead. Together they unravel how one of the biggest myths in history took hold and why the Maya were unable to accurately predict the apocalypse. But they also delve into why, according to Michael, 2012 was the year an old world was discarded and a new one began to emerge. It was, afterall, the year a novel technology became unavoidable and we began to abandon a shared culture for millions of fragmented realities. Along the way they also explore the science of confirmation bias, why humans are fascinated by the end of the world, and whether technology has made us less connected...or reconnected us in a different way. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit https://www.cancerresearchuk.org/our-research/rest-is-science.

  The Hole In Your Brain That Makes You Doomscroll 19.07.2026 49p

  Why can't you leave a sealed envelope unopened? Professor Hannah Fry begins by refusing to allow Michael Stevens to open a mystery envelope addressed to him. A small act of torture that turns out to be the perfect way in to today's subject: curiosity. What is it, why does it feel almost physical, and how far will people actually go just to resolve a nagging uncertainty? From there Hannah and Michael trace curiosity's surprising reputation through history; how for well over a thousand years it was branded a vice, even a sin, before a couple of inventions flipped it into a virtue almost overnight. Along the way they delve into the psychology and neuroscience of this itch. Why your brain can't stop worrying at a missing answer, why getting something wrong could be the key to remembering it, and which animals share the drive (and one surprising creature that doesn't). Plus curiosity's darker side, the way the modern world has learned to hijack the very same circuitry, and a rather lovely story about how a Mars rover got its name. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  Forensic Science And The Champawat Tiger 15.07.2026 41p

  It begins with a discovery in a loft: a full man eating tiger skin, brought back from a village in northern India where Professor Hannah Fry's ex-mother in law grew up. That find sends Hannah and Michael Stevens into the strange world of man eating big cats: a tigress blamed for a staggering number of deaths, what can turn a tiger toward hunting humans in the first place, and how India now borrows techniques from forensic science…effectively putting a tiger on trial before deciding its fate. And it raises an uncomfortable question: when a critically endangered animal kills a person, how do you weigh human safety against saving a species? Plus the wonderfully simple trick that stops attacks in their tracks.Then it's over to your questions, taking in some of the universe's most beautiful coincidences, from the sky above us to the clockwork of distant moons, and a mysterious number that once haunted one of the great physicists.

  All The People You Don't Know 12.07.2026 56p

  Do your friends actually like you? Does an acquaintance think you’re closer than you are? This week, Hannah Fry and Michael Stevens explore the surprising psychology of friendship, from familiar strangers and para-social relationships to the unsettling discovery that nearly half of friendships may not be mutual. Why are we so bad at judging who considers us a friend? Why do strangers often have a bigger impact on our lives than we realise? And why do your friends almost certainly have more friends than you do? Along the way, they uncover the science of social networks, loneliness, influence, popularity, and the famous friendship paradox, revealing how the hidden connections around us shape our health, happiness, and behaviour.

  An Honest Dad Ranking (Out Of All 2 Billion) 08.07.2026 41p

  The statistical reality of "The World's #1 Dad Mug" is nothing but a well meaning lie. In this episode of The Rest Is Science, Michael brings another treasured artifact into the studio: a mug gifted by his daughter. Rather than claiming the top spot, the mug features a specific, mathematically defensible ranking of his fatherly abilities. If he's not the very best...surely he's in the top percentile?
