LIGO did not respect fundamental methodology of physics which is following:
1. Observation of given phenomena
2. Building of theoretical model of the phenomena
3. Experimental prove or disprove of phenomena.
The fact is that GW were not observed yet. LIGO started with
2. Equations which show that GW are causing length contraction of length prolongation. This is only theoretical model which do not assure that GW exist.
On the base of 2 LIGO did experiment where interference pattern of laser light is observed which means 3. There is absolutely no direct relation between interference pattern 3 and prediction of the model of length variation of beams of interferometer 2.
LIGO now on the base of 3 says that 1 exists which is pure nonsense. Popper would turn in grave seeing all that makeup physics, Max Planck and Einstein too. This research of LIGO is pure example of failure of scientific methodology which will enter the history of physics.
