One million times faster than a bullet and caught on camera

What travels one million times faster than a bullet? A photon—light, in other words—and scientists at M.I.T. have built a device that can capture light in motion. The video below replays images recorded one trillion times per second; movies are shot at 24 frames per second, to give you a point of reference. What you will see is a pulse of laser light travel through a Coke bottle.

We all know that light travels, but we've never seen it traveling before, until now.




Volumetric Propagation: "The pulse of light is less than a millimeter long. Between each frame, the pulse travels less than half a millimeter. Light travels a foot in a nanosecond and the duration of travel through a one foot long bottle is barely one nanosecond (one billionth of a second)"
