comment What did LIGO Actually See? (Gravitational waves discovery)
@ChrisMueller: I suspected it was GPS, but didn't have time to look it up at that moment. Thanks!

Atomic clock, GPS, or others. There are a lorry of ways to record at that resolution

They record them at the same time, but due to the speed of the wave, it took 7ms difference in time to recurve the signal.

comment At what distance from Earth would our Sun be the same apparent magnitude as the next brightest star in the sky?
Different question entirely, but the distance is the thing of note. Moving in a direction that isn't directly towards the object would just change the distance formula.
