plus , you should practice your paragraph comprehension
your flawed comprehension does not equate to you being right.
You have two LIGO's turn the seismic suppression off one and leave it on the other .... DOH.
Wait for a reasonable earthquake now compare results smile
You can tell if the seismic suppression works pretty dam easy and put error bars and numbers around the suppression ability.
also: a laser beam that is being moved up and down to
suppress seismic motion will cause the laser beam to
form a wave.
and: seismic motion waves caused at the earths surface
radiate outwards from the epicenter so the two ends of the tunnel will respond to each seismic wave at different times.
I did not read where there was a detected motion wave
during the recording of the proposed gravity wave detection
event but the graphs show that what was detected was
coming from below the ligo.
the graph shows the gravity intensity in both (+)and(-)
since the desired ligo detection was the detection of the
gravity of a black hole system beyond the earth then I
would think that the engineers and designers of the ligo
would have used the (+) side to show positive gravity
fluctuations of the black hole system not the gravity
fluctuations of the earth.
