Stellar Nucleosynthesis: The Forge of Heavy Elements
Dead stars built you. Sounds wrong, but your iron was forged in stellar cores, where gravity squeezes light atoms together. Hydrogen becomes helium, then carbon, then heavier layers stack up like an onion around the center.
Dead stars built your body. Every iron atom in your blood was forged inside a stellar core, where extreme gravity fuses light atoms into heavier ones. Hydrogen becomes helium, helium becomes carbon, layer by layer.
But this engine hits a wall at iron. Fusing iron absorbs more energy than it releases. The core stalls. Gravity wins. In seconds, the star collapses inward at a quarter the speed of light.
That collapse triggers a supernova. Neutrons slam into atoms so fast they capture dozens before they can decay — forging gold, platinum, and uranium in seconds. The heaviest elements, built in a flash.
Those atoms scattered into space, drifted for billions of years, and became part of everything around you. The gold in Earth's crust, the iodine in your thyroid — assembled inside dying stars. You are stellar wreckage, repurposed.
