Look up MATTER WAVES in any university textbook. Find DeBroglie’s U=c^2/v equation for the speed of a matter wavecrest. This explains why the sun’s gravitational influence on the earth isn’t 8 minutes c-retarded, it’s instantaneous(.001655 sec)and why physicists haven’t found gravity waves moving at c. Einstein/relativists tried to bury DeBroglie because of that equation, putting him in the crazy aunt alice category, now THEY are being buried by “spooky action at a distance” : momentum-line matter waves at c^2.
