Dear Friends, My Theory already derived that the Gravitational waves travel at the speed of Dark Energy i.e., 9.887 x 10^12 m/s. The speed of Dark Energy was proved in 3 cases in my Theory to be 9.887 x 10^12 m/s. Moreover, the speed of Dark Matter was derived as 2.1456 x 10^23 m/s (and proved in 3 or 4 cases, besides being experimentally verified). Please, join the discussion in Academia :
