These are photographs of the first few milliseconds of nuclear explosions. They lead scientists to several new discoveries as to how nuclear bombs worked. But how do you capture the first millisecond of a nuclear bomb? With several rapatronic cameras, a Kerr cell, and a little physics.
Nuclear explosion photographed less than one millisecond after detonation. From the Tumbler-Snapper test series in Nevada, showing fireball and "rope trick" effects. The fireball is about 20 meters in diameter in this shot.
