## Main Question or Discussion Point

where in the Einstein field equations is the energy and momentum of the gravity waves themselves Rμγ- 1/2gμγ R = 0 doesn't mean the space is flat there are waves in the fabric of spacetime itself so how and where does the energy and momentum of these waves manifest itself Tμγ is the energy density or the matter density so the answer must lie on the right hand side of the equation but where?
