  Einstein gravity with extra dimensions or alternative gravity theories might
suggest that the gravity propagation speed can be different from the light
speed. Such a difference may play a vital role in the primordial universe. In
recent, Kopeikin and Fomalont claimed the first measurement of the gravity
speed by VLBI. However, the measurement has no relevance with the speed of
gravity as I had shown before the observation was done. It seems that our
conclusion has been established well by re-examining recent papers with great
care.
