Kopeikin (sk) facilitated by Stephen Speicher in connection with the 2002 September 8 Jupiter-quasar appulse and the “speed of gravity” issue. Further information about the views expressed here may be found in the just-published paper: “Experimental Repeal of the Speed Limit for Gravitational, Electrodynamic, and Quantum Field Interactions”, T. Van Flandern and J.P. Vigier, Found.Phys. 32(#7), 1031-1068 (2002).
