LIGO

The LIGO detected celestial gravitational waves that originate from a 21,000 binary pulsar (PSR 1913+16) that produces a ΔL = 10^-18 m disturbance of the interferometer mirror but Creswell-Jackson (2017) discredited the LIGO experimental results as background noise (Creswell-Jackson, Abstract) since the mirror displacement of ΔL = 10^-18 m is less than the diameter of an electrons which is to small of a displacement to experimentally measure. The formation of a wave requires a medium, composed of matter yet gravitational waves propagate in vacuum of celestial space that is void of matter. Einstein uses a space-time curvature to justify the formation gravitational waves using the varying relativistic (time-space) translational velocity v that is formed by the earth's daily and yearly motions but gravitational waves that are propagating in stellar space are not effected by the earth's daily and yearly motions.

I'm not totally sure what your post is trying to say, can you explain?

The challenge from the Neils Bhor Institute in Copenhagen proposed that noise in Ligo's two detectors correlated. It was suggested that the time delay associated with the correlations matched the time it would take a gravitational wave to travel between the two detectors.  Creswell then reasoned that the results detected may ( stress on may ) be correlated by noise. The LIGO team have replied to the suggestion by saying  the correlation claimed by Creswell and his team are not present in the data itself but rather is induced by the methodology used by Creswell's team in their analysis.  I guess subsequent detection events will give clarity  but at the moment the LIGO team are standing by their results. 

"the formation of a wave requires a medium, composed of matter yet gravitational waves propagate in vacuum of celestial space that is void of matter."

 Wave formation does not require matter, perhaps the most obvious example being electromagnetic radiation (em) . We know that em waves propagate by the perturbation of the electrical and magnetic field (quantum field theory).  I'm certainly no expert on the nature of gravity waves but I guess it is not improbable that what is being proposed is that a massive gravity disturbance causes a perturbation in space time with subsequent propagation in similar wave form.   Any perturbation of  space-time due to the Earth's influence  is simply too small to show its fingerprint on any subsequent gravitation wave originating from the massively energetic events which the LIGO team are detecting. I guess it would be like trying to detect the signature ripple caused by the filp of a fish's fin during a tsunami event .   Which goes to prove , fishing is fraught with danger
