Aberration and the speed of gravity
Abstract
The observed absence of gravitational aberration requires that `Newtonian' gravity propagate at a speed c_{g}>2×10 ^{10}c. By evaluating the gravitational effect of an accelerating mass, I show that aberration in general relativity is almost exactly canceled by velocitydependent interactions, permitting c_{g}= c. This cancellation is dictated by conservation laws and the quadrupole nature of gravitational radiation.
