RE: Detecting black holes with telescopes and gravitational waves
I guess I need to read more about what exactly these detectors are. I am just surprised by the level of precision (10-19 is pretty small, 1000X smaller then the radius of an electron)
The key is really the interferences. I tiny variation in the length of the arms induce a noticeable (and much easier to observe) interference pattern.
