The Deficient Observations of Light Deflection Near the Sun

We report a full analysis of one of general relativity's predictions, which claims that light should be deflected by solar gravity. Experiments using visible light as well as radio signals are examined. The Eddington's observational expedition, used to confirm Einstein's predictions on the deflection of light by the Sun, was using a four-inch telescope carried in the jungle. Assuming a perfect optic, the theoretical limit of resolution is 1.25", but some of the displacements presented were sometimes of the order of 0.01". In daytime observations, about 30" resolution is expected. That deflection is so difficult to observe near the Sun in daytime, that even the largest telescope in the world is still unable to confirm it after 80 years. This paper also shows that the corresponding delay for a radio signal passing near the Sun does not permit to get a more reliable result. We show that no one can seriously claim that light is really deflected by the Sun. There are even serious reasons to believe that this phenomenon does not exist.
