This article will propose and empirically validate a new hypothesis for the speed of light. The main result of this proposal is that Galilean/Newtonian relativity is more accurate than special relativity, even for relativistic speeds. The hypothesis is “Light moves in a free space at a speed c, in the inertial reference frame of the smallest celestial particle containing the light source. Once it is released outside the effect zone of this celestial particle, its speed will be c in the inertial reference frame of the bigger celestial particle or the celestial particle that will pick up it. Celestial particles act as carriers for Light.” Another important result for of this proposal is that the absolute/relative speed of light or any other particle may exceed the value c. Through the article, we will deeply validate this proposal using famous phenomena and experiments such as Aberration, Doppler Effect, Binary Stars, Headlight Effect, Michelson-Morley Experiment, and Time Dilation.
