On the other hand, taking equation (5) and substituting t_P by its value ( /(2ƒÎ) G/c⁵)^1/2), we can find G²: ZP ZP P ZP c G c G t G ƒÂ ƒÎ ƒÎ ƒÂ ƒÂ 5 2 5 2 2 2 1 1 = Ë = = . (9) Now, equaling equations (8) and (9), we get ZP ZP c c ƒÏ ƒÎ ƒÂ ƒÎ 7 2 5 2 2 = , (10) and in consequence   2 c ZP ZP ƒÂ ƒÎ ƒÏ = , (11) which means that QV energy flow is a function of QV energy density and the spee d of light, thus unifying these two apparently different QV-parameters. Conclusions and Discussion 1. Gravitation as a Combined Force of Mass Attraction and QV Repulsion Through (5), Newton’s equation of gravitation (1) can be now expr essed more precisely (at quantum level) by the following equation: 2 2 1 2 1 d m m t F P ZP ƒÂ = , (12) where G has been substituted by a function of QV energy, and ƒÂ_ZP reflects the value of the “ZPF mass-density equivalent”, which can be now calculated exactly through ( 6) and/or (7).   Since the left component of (12) is a constant, and the right a variable, they are mutually independent and can be treated separately. In consequence, the first we  observe, while regarding equation (12), is that it is composed of two components: a QV (ZPE) component to the left, and a mass attraction component to the right. Secondly, ƒÂ_ZP is inversely proportional to gravitational attraction (F), what consequently means in principle that ƒÂ_ZP reduces gravity (while mass increases gravity). In consequence, we can call the right component “pure mass attraction” and the left, “vacuum repulsion reaction” since mass is obviously the inducing component of gravitation and QV probably reacts (as per the “cause-effect” principle) to the pre sence of mutually attracting masses. In summary, we have found through equation (12) that gravitation is a combined force and that the QV-component (to the left) is opposed to the mutual gravitational attraction of masses (component to the right). The sense of this apparently complex gravitation-generating system in the universe is probably that of stabilizing gravitation, thus avoiding unbi ased extreme mass-attractive forces, by opposing a constant reaction effect through QV. If there were no QV in the universe, G would be equal to 1 m³kg^-1s^-2 (since it would mean that there is no QV reaction) and gravity would be much stronger than it is at present (exactly 6.673x10¹¹ times stronger, since that would be the 4
