It is easy to say "We found it" and dance around the room. But here there is no reference to magnetism or how the Zeeman effect would be involved. The LIGO interferometer is a Michelson laser based system and would be skewed by magnetism. This is not discussed in the paper on the findings. This is poor science, since a entire set of forces I.e. magnetism is not examined as a possible producer of these waves. Is it more likely, since the Earth is a rotating magnet, that these waves would be magnetic.
The main issue with these gravity waves is they rely on gravity. No force has been found at CERN or the other colliders showing a force called gravity. This is a problem for the conclusions at LIGO since they are based on gravity. They have been looking for the force called Gravity for 70 years at those machines. It would have been the first force found since it is suppose to permeate the universe between objects.
Also after 400 plus years Gravity is still a 2 body equation. So technically it would have no effect on the Earth since it is just a 2 body equation.
