frobs answer is of course right, but theoretically - given enough resources, almost all phenomena should be observable. Imagine having a oscilloscope which measures once every 100 ms (Really slow i know). Now all you need is a 100 oscilloscopes, put in a phalanx seperated 1 ms each and a way to measure their clocks drifting. Given good enough "stitching" algos, any event above the theoretical limit of the nyquist theorem should be observable. https://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampling_theorem https://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampli... This answer simplifies alot and of course,one only gains a stop-motion picture show of the observed phenomena, but none the less..
