Does detector LIGO work on freewill only?

[theBorg]

If they are rigidly attached to the arms of LIGO, then, there is the True God. They are attached rigidly, according to the theory of the LIGO: Soviet Physics JETP, v.16, № 2, 433, 1963). To not offend the atheists one writes everywhere the lie: "the mirrors are free-moving". The Science is about the politics, and the politics likes the tolerance.

Come on... I just posted pictures of the actual pendulum assembly.

If one hangs a mirror on the rope anywhere in the world, will it vibrate at the arrival of a gravitational wave? Even if it will, then the magnitude of the vibration does not depend on the fact that 4 km away the other mirror is suspended. Mirrors are independent. Is it logical? Therefore, the mirrors simply screwed tightly to the ends of the LIGO detector.
