A relativistic Newtonian mechanics is a contradiction in terms. The fact is that general relativity makes the predictions about light bending /without/ reference to Maxwell's equations or anything about light /other/ than it traveling on a null path. Is there a particular reason you can't open up a textbook, see the derivation, repeat the derivation, and compare with observation? > > André Michaud
