NASA and the Cosmic Tragedy of Apollo 18–20

The Multiverse Employee Handbook is taking a brief holiday. Our narrator is currently horizontal in a field outside Innsbruck, the Alps are doing their thing, and Season Four is being assembled somewhere in the quantum foam of late summer. We'll be back soon — with more actual science, delivered with the calm urgency of someone who has just realised the atoms in their deckchair were forged inside a dying star. Season Four arrives at the end of summer. Try not to collapse your wave function while we're gone.

Season 4 is Coming: The Universe Remains Uncooperative The Multiverse Employee Handbook returns for a fourth season of science, satire, and the quiet suspicion that reality was written by a committee with no editorial oversight. Season 4 dives deeper into the genuine absurdities of existence—the kind that come with equations, experimental evidence, and the occasional Nobel Prize. We'll be exploring everything from the arrow of time to the nuclear physics happening inside your own body, from dark energy's relentless campaign to stretch the cosmos into nothingness, to the uncomfortable probability that none of this is real and the simulation is running low on memory. All of it accurate. All of it researched. All of it delivered with the calm, measured tone of someone explaining that the floor beneath you is mostly empty space and always has been. Meanwhile, at Quantum Improbability Solutions, the Square-Haired Boss remains employed—a fact that challenges our understanding of natural selection, corporate governance, and the second law of thermodynamics in equal measure. New episodes arriving soon. Subscribe now, while the concept of "soon" still means something in your local spacetime. The Multiverse Employee Handbook. Revealing that science has been funny all along, and someone really should have mentioned it earlier.

Exploding stars, Van Allen's doughnuts, the surprisingly violent history of how we first noticed, and why the most sophisticated radiation shielding strategy currently available is, in certain respects, a cave. Plus: NASA's Artemis programme is heading back into deep space for the first time in fifty years, and this time we're bringing considerably better instruments.

Humanity has spent thousands of years naming constellations, building calendars, and writing mythology onto the night sky — largely ignoring the actual stars next door. 🎧 Love the show?

Space is stranger than advertised. The neighbourhood association has concerns.

Eleven point nine light-years away, in the constellation of a mythological sea monster, sits a star that astronomers, SETI researchers, and science fiction writers have been collectively obsessed with since 1960. 🎧 Love the show? Help us improve in 2 minutes: https://tally.so/r/nr1evM In this episode of The Multiverse Employee Handbook, we visit Tau Ceti — the Sun-like neighbour that has everything you'd want in a nearby stellar system: stability, age, a habitable zone, and almost certainly planets. Almost certainly. We explore the full and rather remarkable story of this ancient star, from Johann Bayer's 1603 star atlas and Frank Drake's original SETI search, through decades of planet hunting, a debris disk of genuinely alarming proportions, and the latest findings from the ESPRESSO spectrograph, which has made everything considerably more complicated. We also ask whether Tau Ceti represents a genuine opportunity for life beyond our Solar System — and why, despite everything, it refuses to stop being interesting. Plus: Ryan Gosling, the Kobayashi Maru, and the nine-billion-year question the universe is still sitting on.
