When I was a kid and the concept of "the speed of light" was first introduced to me, I tried to see if I could catch it with the naked eye. For hours, I would sit in my room (we didn't have cable) and flick the light switch on and off, staring at the part of the room furthest from the overhead light bulb, the goal being to pinpoint the exact moment when the light had blanketed every other part of the room but left the corner briefly untouched. Once or twice, I even saw it. (Or thought I did, at least.)
That's the memory that bubbled to the surface when I heard the news that the folks at MIT Media Lab had built a camera that can actually capture the movement of light. By capturing a trillion-frames-per-second, the video can actually capture the speed of light.
Now, the scientific details about how the camera works are a bit above my pay grade (for a good summary, check out the official MIT press release), so I'm not even going to attempt to unpack any of the messy details here. Instead, simply enjoy the video:
