Scientists Shoot World’s Fastest Film at a Quadrillion Frames Per Second

German scientists have been awarded a Guinness World Record for “fastest movie” after successfully capturing two images of an X-ray laser beam 50 femtoseconds apart. One femtosecond is equal to one quadrillionth (or one millionth of one billionth) of a second. Here’s some science talk explaining it:

[…] the scientists split the X-ray laser beam into two flashes and sent one of them via a detour of only 0.015 millimetres, making it arrive 50 femtoseconds later than the first one. Since no detector can be read out so fast, the scientists stored both images as superimposed holograms, allowing the subsequent reconstruction of the single images.
With these experiments, the scientists showed that this record slow motion is achievable. However, they did not only take the world’s fastest but probably also the shortest film – with just two images. Thus, additional development work is necessary for the use of this method in practice. [#]

And we thought one trillion frames per second was impressive…

    That’s nothing, I just shot some footage at 20×30 bazillion frames a second, I just have one frame though but trust me, where’s my trophy.

    Hmm… You should definitely contact them about that:

    can we see that frame pretty please? i suppose it clearly shows something that is proof of an exposure of 1/20x30bazillionth of a second…

    Duh, check the exif.
