A laser pointer at 2 billion fps makes the speed of light look... kinda weird (2025)

It took almost a year, but today I finally get to show off a TWO billion frame per second camera! I really want to record refraction, interference, and other awesome stuff with this camera, but today I'm looking into a really strange quirk of the speed of light. In a way, understanding this weird phenomenon is kind of a prerequisite for everything else I want to do with this camera - I hope you find it as interesting as I have!
