We calculate the delay in the propagation of a light signal past a massive body that moves with speed v, under the assumption that the speed of propagation of the gravitational interaction c g differs from that of light. Using the post-Newtonian approximation, we consider an expansion in powers of v/c beyond the leading " Shapiro " time delay effect, while working to first order only in Gm/c 2 , and show that the altered propagation speed of the gravitational signal has no effect whatsoever on… CONTINUE READING
