Gravity wave detection correlated with an electromagnetic observations will narrow the measurement accuracy to better than a percent. A similar correlation was made between SN1987A neutrinos and photons.

When General Relativity is tested to relatively high precision, and it has been tested many times and in many ways, it always seems to be verified, i.e., its predictions come within the error bars of the experimental result. If gravitation, or perhaps better said: spacetime curvature, propagated at a speed different from c, then I think the binary pulsar experiments would have indicated this. I am certainly not an expert on this topic, and would defer to someone like Clifford Will, or other GR experts, which probably includes Tom Roberts and Steve Carlip. RLO www.amherst.edu/~rloldershaw
