Abstract
In this paper, a standard method is provided to calculate the gravitational deflection of light in the solar system by using the Newtonian theory of gravity. The equation of light’s motion in general relativity is compared with that of the Newton's theory of gravity. It is proved that a constant term is missing in the motion equation of general relativity. This constant term is critical to the orbital shape of light’s motion in gravity field and causes serious problems so that it can not be correct. The orbital poles of light’s motion of general relativity is also calculated. According to the theory of algebraic equation, the orbital poles are determined by a cubic equation of one variable. The calculation of general relativity assumed that light from stars in outer space passed through the solar surface, which was equivalent to assume that the solar radius was a root of the cubic equation. However, it is strictly proved that the solar radius can not be the pole of motion equation of general relativity. The orbital poles of light are located in the interior of the sun which are not far from the center of the sun, so all of lights from stars in outer space would enter the solar interior and disappear. It is impossible for the light to be seen by the observers on the earth surface, but this is not the case. The reason is just that the motion equation of motion in general relativity is missing a constant term. It means that the Einstein's prediction that light’s deflection angle was 1.75” in the solar gravitational field can not be correct and general relativity can not hold.
