So, some scientists found a way to have a camera that can produce videos that shows the motion of light. You could call it a camera that captures roughly a trillion frames per second.

In reality it doesn't, as it requires you to make the same recording many many times, and then they piece it together to get video footage that captures light moving. (Thus the slowest fastest camera)

The first scene and the scene starting at around 2 minutes are both awesome as hell.
