Stellar nucleosynthesis Memes

The cosmic terror is real! Massive stars casually fuse hydrogen through silicon without breaking a sweat, but when they reach iron, it's game over. Iron fusion actually consumes energy instead of releasing it, causing the star's core to collapse catastrophically within seconds. The resulting supernova explosion is basically the stellar equivalent of "I've made a terrible mistake." The universe's most dramatic energy crisis happens because iron's nucleus is too stable—it's literally too perfect to participate in the stellar fusion party.
