@astralfrontiers: In a cloud chamber, you can actually see invisible particles streaking through vapor—these are cosmic rays, high-energy particles from space, creating glowing trails of ionization. But these trails aren’t just science tricks—they’re signs of something far deeper. 🔹 Cosmic rays, many originating from supernovae or even more exotic events like black hole jets, bombard Earth constantly. 🔹 When they hit atoms in our atmosphere, they create cascades of secondary particles, some of which reach the surface—and even our DNA. 🔹 These subtle interactions have caused random mutations in living cells for billions of years—sparking genetic variation, evolution, and the diversity of life on Earth. Without these ancient stellar explosions, life may never have evolved beyond microbes. So in a way… we owe our complexity, creativity, and consciousness to exploding stars lighting up the galaxy. You’re not just made of stardust. You were changed by it. Credit: BBC Earth, @profbriancox #AstralFrontiers #CloudChamber #CosmicRays #Supernovae #LifeAndMutation
