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.

This answer simplifies alot and of course,one only gains a stop-motion picture show of the observed phenomena, but none the less..
