Superior Brother Steve Carlip, Aug 1 1997: "In special relativity, the speed of light is constant when measured in any *inertial* frame. In general relativity, the appropriate generalization is that the speed of light is constant in any freely falling reference frame (in a region small enough that tidal effects can be neglected). 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, basically because of the effect of gravity (spacetime curvature) on clocks and rulers." Steve Carlip carlip@dirac.ucdavis.edu Roberts Roberts in my view the last wisdom: "In such a frame, the speed of light can differ from c, basically because of the effect of gravity (spacetime curvature) on clocks and rulers." is EXTREMELY SILLY. What do you think? Do you find it EXTREMELY CLEVER? Pentcho Valev pvalev@yahoo.com
