Gravitational waves are continuously strechingstretching and squeezing the shape of earthEarth.Using Using this fact, LIGO is detecting it by interference of light.But But the Sun and MoonsMoon's tidal effects are also trying to stretch the earthEarth.Does Does this affectsaffect the detection of G.Waves?gravitational waves?If do If so, then how do they eliminates thiseliminate these effects ???
