Recently, a group of scientists at Germany’s largest particle physics center were awarded a Guinness World Record for “fastest movie” after shooting two frames merely 50 femtoseconds apart (or about 800 billion times quicker than in modern film — a femtosecond is equal to one quadrillionth of a second) using an X-ray laser. We know, we know, two frames of lasers are not that exciting, and this experiment has probably created the world’s shortest film as well as the fastest, but Oscar-winning or no, this is still the smallest interval between frames every recorded — and we’re having fun just imagining how tiny a period of time a femtosecond is.
