'LIGO must be at least 99.999% mechanically decoupled from Earth to be sensitive enough to detect gravity waves."
What on Gods green earth are 'gravity waves'????? From my study of physics, gravity is a constant force that exists in proportion to an objects mass. Thereby it is a constant for any given object. For gravity to be a wave the mass would have to vary at the frequency of the wave...how many objects do you know of that their mass or weight fluctuates in a wave-like fashion? Sorry not buying this concept at all.
