What happens if you just keep slowing down time… and then keep going? This new video from Veritasium starts with a century-old strobe trick that can freeze a tennis ball mid-smash, then cranks things up to quadrillion-FPS cameras that literally watch light crawl through space. And it doesn’t stop there.

Along the way, you’ll meet Harold Edgerton, see why some “cameras” can move faster than light without breaking physics, and visit giant particle accelerators that let scientists stitch together movies of electrons sloshing around molecules at an effective quadrillion frames per second.

It’s an enlightening ride from popping balloons to watching reality itself update frame by frame, proving that slowing time enough doesn’t just reveal motion… it reveals entire hidden worlds. Check it out!
