and or the propagation speed of gravity can be > c. General relativistic orbits can be completely explained with equations of motion derived from the principle of extremal aging for energy per unit mass and angular momentum per unit mass. If what 'you said'("So GR assumes an infinite velocity for the changes of spacetime curvature, so to speak") was what GR predicts then Kopeikin wouldn't have bothered to formulate an experiment which could quantify (to some level of uincertainty) what speed gravity propagates and there would be no difference of opinion between crackpots like Van Flandern and gravitational physicists. The results of Kopeikin's experiment will be published in the near future.
