Could the origins of life on Earth trace back to a natural nuclear reactor? Long before humanity split the atom, nature itself may have done it first. In this episode, we explore the astonishing possibility that self-sustaining fission reactions—like the Oklo natural reactor in Gabon—once powered the chemical engines of creation.
