You could actually bother to read stuff

Yeah they have to suppress seismic activity and all earthquake stuff is well out of frequency but you layman never actually want to learn anything.

One of the tests of LIGO is to turn off the active suppression and actually detect seismic activity.

You could also google LIGO noise floor plots and actually look at the levels. The main stuff they have trouble with is man made and close to the LIGO's hence the signifcance of having two detectors separated by long distances. Each LIGO will also go thru a calibration process before and after runs to make sure they held calibration throughout the run.

Love the grasping at straw efforts. Never let the truth get in the way of a good religious story hey Paul. Perhaps GOD coughed or Pink Aliens did a war dance on top of LIGO they haven't calibrated those.

How about before posting ever more stupid things you all bother to actually read about the operation of LIGO, which is actually half the story of LIGO how to eliminate more and more noise and get detection sensitivity to what was required.

All of this stuff is really easy to find before posting stupid arguments.

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
