This book includes volumes V and VI of the Theory of Global Equivalence.Among the most important aspects, we can highlight the following:-The non-relativity of time and space within the scientific and objective scope of reality.-The observers non-dependence of physics reality. -The existence of a constant speed of light only within the its natural system of reference or particular intensity of gravitational energy, immersed in the three-dimensional Euclidean space of Greek metrics.-The speed of light is additive in respects to that of its natural system of reference through which it moves. Light cannot exist without gravity or, better said, its reticular structure. -The distinction between physics velocity and abstract or conventional velocity, such as the velocity of two objects separating.The Global Gravity Law deserves special mention for implying a different explanation about the predictions of the General Theory of Relativity of Einstein by means of a small adjustment of Newton s Law of Universal Gravitation. I am referring to the effect of the gravitational lens, the gravitational red shift of light and the precession of the perihelion of Mercury.
