What If Every Nuclear Weapon Went Off at Once?

What if every nuclear weapon on Earth went off at once? Right now there are around 12,000 nuclear warheads on this planet, sitting in silos, submarines and storage bunkers across nine countries. This video asks what would actually happen if all of them detonated in the same minute, and the answer is stranger than the one most people expect. It begins with an ordinary morning. A train pulling out of a station in Chicago. A market opening in Lagos. Children walking to school in Tokyo. Farmers in the fields of Punjab. None of them know anything is wrong. Then one launches. Then another answers. Then every arsenal on Earth empties itself in under thirty minutes. In this documentary we follow exactly what the physics does next: the fireballs hotter than the surface of the Sun, the overpressure waves that flatten steel-framed buildings, the thermal pulse that ignites cities from the horizon, and the firestorms that follow. Then we get to the part almost nobody gets right. Earth would not be destroyed. The crust would not crack. The planet would not be blown out of its orbit. All 12,000 warheads together carry a tiny fraction of the energy of the asteroid that ended the dinosaurs. The planet survives easily. What does not survive is the thin layer of climate and agriculture that we happen to live inside. Because the real killer is not the blast. It is the smoke. Enough soot lifted into the stratosphere to block sunlight for years, dropping global temperatures, collapsing harvests on every continent at once, and starving far more people than the explosions ever could.
