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 cg 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/c2, and show that the altered propagation speed of the gravitational signal has no effect whatsoever on the… Expand

Comment on ‘Model-dependence of Shapiro time delay and the “speed of gravity/speed of light” controversy’
In a recent paper published in (2004 Class. Quantum Grav. 21 3803) Carlip used a vector–tensor theory of gravity to calculate the Shapiro time delay by a moving gravitational lens. He claimed thatExpand
