thank you very much...another question I know that for example that the Ricci tensor...is from the contracted Riemann Tensor via the metric...but what is the Weyl tensor and how do the Ricci and Weyl curvature differ? Thanks!
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...
