By Casey Chan on at

Where does gold come from? The answer: space, basically. Supernovae, specifically. Alchemy, sort of. So gold doesn’t actually originate from the core of Earth but actually from a star explosion that showers the universe with debris and well, gold. That means there’s not that much of it actually on Earth (all the gold mined in history only fills three Olympic-sized pools) but we can now make our own gold!

Too bad it just takes forever. Find out more about the origins of gold and the future of it in this fascinating animation explainer from David Lunney and Andrew Foerster for Ted-Ed.
