A Prediction of Quantized Gravitational Deflection of Starlight

Abstract

It was argued previously that the factor 2 emerging from Einstein's General Theory of Relativity (GTR) and used in Solar eclipse measurements by Eddington as the clearest indicator yet that Einstein's GTR is indeed a superior theory to Newton's theory of gravitation may not be adequate as an arbiter to decide the fate of Newtonian gravitational theory. Using ideas from research that we have carried out over the years, we show that the gravitational deflection of a photon may depend on its spin in such a manner that if photons of different spins where to be observed undergoing gravitational deflection by a massive object such as the Sun, the resulting deflection may be seen exhibiting distinct deflection quantization as a result of the quantized spins.
