Did you know that there exists a camera that can capture one trillion frames per second and is fast enough to capture moving light? Me neither, but apparently it's been around for nearly two years and was created in the MIT Media Lab.
The video embedded above demonstrates how the camera is able to capture photos moving through space. As the narrator describes, you've probably seen images of a bullet traveling through an apple. Photons move about a million times faster than bullets, so capturing them is no easy feat.
This kind of technology could be useful in medical imaging, industrial or scientific use and perhaps even one day, consumer photography.
