From nuclear nightmares to reality-breaking weapons, we examine how science and fiction imagine the end of everything. What happens when weapons don’t just destroy worlds but unmake reality itself? Explore the science of apocalypse.

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. From radioactive geysers and mineral-rich pools to the first self-re...
