In the video the light traveling through the bottle is not 'femto' (i.e 10[SUP]−15[/SUP]) it would have to capture at a 'quadrillion' frames a second. .. In the video its travelling at 10 billionths (10x10[SUP]−9[/SUP]) which is actually 10 nano-seconds. ... That example should be called 'nano-photography' because its 10,000 times too slow. .. still very impressive.
Its crazy to actually think that there is a fundamental limit to how slow time can go 'Planck time' or 'Plank-second' (10[SUP]−44[/SUP]) ...
