Does detector LIGO work on freewill only?

[Whateverist]

The theory of this detector of gravitation waves (the discovery was in 2015) is in article in "Soviet Physics JETP", v.16(2), 433, 1963. But there the frequency of the laser radiation is “vibrating”, ie. is changing (when the gravitational wave comes in). But this is forbidden by Einstein's equivalence principle, which states: all observations are the same in all laboratories throughout all the time.

The godless occultism has arrived into Science, see also in Google "the human sacrifice in CERN".

Most apologists take at least ten inches of text to spew this much idiocy.  Usually brevity is the soul of wit .. not sure what went wrong in this case.
