Honest Carlip your brothers Einsteinians (Lee Smolin etc.) have extracted a lot of career and money from this so you should not be so hostile. Instead of waiting for a "real effect", just analize the Pound-Rebka experiment: does it confirm variable speed of light, or does it confirm constant speed of light? Remember this: http://math.ucr.edu/home/baez/physics/Relativity/SpeedOfLight/speed_of_light.html Steve Carlip: "Einstein went on to discover a more general theory of relativity which explained gravity in terms of curved spacetime, and he talked about the speed of light changing in this new theory. In the 1920 book "Relativity: the special and general theory" he wrote: ". . . according to the general theory of relativity, the law of the constancy of the velocity of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity [. . .] cannot claim any unlimited validity. A curvature of rays of light can only take place when the velocity of propagation of light varies with position." Since Einstein talks of velocity (a vector quantity: speed with direction) rather than speed alone, it is not clear that he meant the speed will change, but the reference to special relativity suggests that he did mean so. (...) In this passage, Einstein is not talking about a freely falling frame, but rather about a frame at rest relative to a source of gravity. In such a frame, the speed of light can differ from c..." > Which situation are we in now?

Shatter this postulate, and modern physics becomes an elaborate farce!....The speed of light is c+v." Pentcho Valev pvalev@yahoo.com
