You've seen slo-mo, but have you really seen slo-mo? Researchers at Washington University in St. Louis have developed a method that allows them to see the movement of light itself by shooting video at a staggering 100 billion fps.
How are they able to do this? Well Nature reports that it's done using a method called 'compressed ultrafast photography' which uses a sensor that is actually able to track the movement of the light.
In this case the light is created in the form of a laser pulse as it moves through the air and is then reflected off a mirrored surface.
The video may seem short but what you're witnessing are trillionths of a second, and only a handful at that.
So why would you want to see light in this way? Well the CUP method will be instrumental in helping researchers further their work on creating the first truly viable invisibility cloaks.
