MIT has built a camera so fast it can capture light itself. The camera records at 1 trillion frames per second, allowing scientists to slow down the fastest thing in the universe and watch it move through a scene. You can actually see light reflect off the floor, pass through fruit, and create shadows with a delay. To put it in perspective, if you filmed a bullet going through an apple with this camera, the playback would take an entire year to watch. This breakthrough opens a new window into ph

A custom-built camera that captures two billion frames per second turns the invisible into something you can almost feel, revealing a beam of light inching through space in ultra-slow motion. Each frame captures just a few centimeters of movement. Researchers use this footage to analyze the timing and behavior of light in ways that were previously impossible. At this scale, the beam can seem to change speed depending on the camera’s position, as tiny delays in light’s travel become visible. The
