What did LIGO Actually See? (Gravitational waves discovery) I am trying to find an original video/image of what LIGO actually saw, but all I can find is artist renditions of gravitational waves.
The actual image isn't much. I was able to find it from Science, and this is all it is:



It's just a ripple, seen at slightly different times from two different observatories. The shift fits perfectly by shifting it by the speed of light difference in their locations. Thus is the proof of gravity waves.

It should be noted that the reason there are two instruments is to provide a cross check against other vibration sources. Each observatory works by detecting vibrations on a 4 km scale, down to a very small order of magnitude (1/10,000 the width of a proton). When the two are compared, then one can assume the signal must have come from a non-local source, which only Gravity Waves fit that definition.
