Nearly two billion years before humans built the first nuclear reactor, the Earth itself turned into a massive nuclear furnace.

Mystery
The missing uranium
A fraction of a percent “missing” from Gabon ore looked like theft—until investigators traced it to prehistoric fission underground.
Prediction
Nature’s checklist
Long before Oklo, physicists argued that enriched uranium, a moderator, enough mass, and few neutron poisons could ignite a reactor without humans.
Safety
Steam as a brake
Boiling away groundwater thinned the moderator, slowed the chain reaction, and let the site cool—then water returned and the cycle repeated.
Long now
Waste that didn’t wander
For billions of years, fission products barely moved—an analog for how the right geology might isolate our own radioactive legacy.
