    Nuclear war could kill millions or billions, but would it really end civilization? We separate blast, fallout, nuclear winter, and Hollywood myths from the physics of what survives and how societies might rebuild.

  5. The Fermi Paradox: Civilization Extinction Cycles

    Episode 912

    Show notes

    What if alien civilizations are common, but keep collapsing before they can spread across the galaxy?

    We explore civilization extinction cycles as a solution to the Fermi Paradox: nuclear war and technological collapse, lost knowledge, isolated colonies, repeated dark ages, and the point where an interstellar civilization becomes too widely scattered to truly reset. Could the Great Silence be a galaxy caught in endless cycles of rise, ruin, and recovery?

  15. White Holes: Do They Exist?

    Episode 906

    Show notes

    White holes are black holes run backward: nothing can enter, but matter and light can escape. We explore whether these strange solutions could exist, connect to black holes, or even hint at how universes are born.

    Show notes

    Mercury may be the Solar System’s first true industrial world. We explore robotic mines, solar furnaces, mass drivers, mobile cities, and how the innermost planet could help build a Dyson swarm.

  19. We Can Make Gasoline From Air. So Why Don’t We? (Narration Only)

    Episode 903

    Show notes
