That equation is correct, assuming "c_r" represents the radial speed in Schwarzschild coordinates. What makes you think it isn't correct? >Apparently the different light bending prediction of 1916 was due to an >important detail of the calculation (which I never reproduced)... The calculation can be found in many good references (including the mathpages you mentioned above), and the source of the doubling of the deflection is clearly shown. > ... and not due to a change in the light speed equation as sometimes > suggested in the literature. The same fact that causes the speed of light to be different in different directions also results in the factor of 2 in the deflection. Perhaps this is what the literature is suggesting? >As a matter of fact, the information about this topic in the literature is >both scarce and confused. I know a guy who was married fived times, and says each of his wives was impossible to live with.
