We've been hearing about trillions in the news so much lately, it's easy to become desensitized to just what a colossal number that is. Recently, a team of brilliant researchers at MIT's Media Lab (ML) built an imaging system capable of making an exposure every picosecond- one trillionth of a second. Just how fast is that? Why, a thousand times faster than a nanosecond, of course. Put another way, one picosecond is to one second as one second is to about 31,700 years. That's fast. So fast, in fact, this system can literally slow down light itself and it does so in a manner unlike any other camera.
