Abstract

The extinction shift principle, the most recent emission theory, leads directly to the solutions of both gravitation and electromagnetism. It has been found that the formulas of both general relativity and special relativity are derivable from a direct application of Galilean transformations of velocities in Euclidean space geometry. The transformations are applied to both the gravitation and the electromagnetism of a theoretically ideal vacuum. The mathematical illustrations show that, as a consequence of Galilean transformations, direct measurement or observation of the primary wave is not possible and neither the primary wavelength nor the velocity of the primary wave is measurable, consistent with all observations. The extinguished primary wave is replaced at interference by a secondary wave that is re-emitted by its secondary source with an extinction-shifted wavelength. The lens, window, or mirror of the measuring apparatus becomes the secondary source. For this reason this effect is coined here as the extinction shift principle. It is herewith mathematically illustrated that this theory is applicable to gravitation as well as electromagnetism.
