We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/5rqQFYdoSPWZ0QLQp27Rmj?si=nLAoFdo5SoSqJ7QoN3eUQQ The Sundown Archive holds the strangest scientific truths, laid out one at a time, meant to be read in a single long sitting. Get comfortable. Get the book: https://publy.store/t/wbpca93 A metal that bursts into flame in water and a green gas that once poisoned soldiers meet, and leave behind the white cubes on your kitchen table. The same crystal lies beneath a vanished sea, drifts around a newborn star, and stains the ice of a moon of Jupiter. Why does this one crystal turn up wherever we look? Tonight's slow journey runs from an X-ray photograph to elephants walking into a mountain at night, from a vanished sea to the sea that still flows inside you. Get cozy and let this slow walk through the physics of salt keep you company tonight. Subscribe to Sundown Science if you enjoy the long way around the universe.
