Close your eyes and let the quiet, systematic science of a nuclear detonation gently carry you into sleep. A blast doesn't end in a flash; its aftermath unfolds in a slow, predictable symphony of physics. When a nuclear weapon detonates, energy is released in a specific ratio: 50% as blast, 35% as thermal radiation, and 15% as nuclear radiation. The blast is a wall of compressed air moving at 1,150 feet per second, lasting only seconds but causing devastating damage. Thermal radiation travels at the speed of light, producing burns and starting fires. In the stillness of the aftermath, a nuclear winter can set in, plunging surface temperatures by as much as 40°F. Let the calm, inevitable physics of the aftermath lull you into a deep and restful sleep.
