Sixth Next Einstein Ed Witten deeply understands how Einstein camouflaged the falsehood of his 1905 light postulate: http://www.claymath.org/Popular_Lectures/Edward_Witten/ Ed Witten: "I've tried to illustrate this by this little magic square where in the upper left I draw a picture that's meant to symbolize a conception based on Einstein's special relativity, dating to the early 20th century, of a massless particle traveling at the speed of light in spacetime. In the picture, space runs horizontally, time runs vertically, and the massless particle travels at a 45 degree angle which is meant to illustrate propagation at the speed of light. Now this is a very naive idea, and Einstein elaborated it into the nonlinear wave equations for which he's really famous \ the Einstein equations which assert that the Ricci tensor of spacetime is zero. These equations encode Einstein's amazingly profound mathematical insight describing just how the curvature of the universe leads to gravitation. So Einstein gave one profound generalization of the naive idea of a light ray in spacetime...." Pentcho Valev pvalev@yahoo.com
