21. Gravity IS NOT a fundamental interaction of Nature.

Gravity is just a philosophical idea, a mathematical construction, an alternative expression of the dynamical origin of the universal energy transfer, the single “real” natural interaction. The gravity factor is not a constant. It is a regular physical quantity, a temporal change of acceleration; there is no “gravitational” action as long as the acceleration remains constant (as in a motion of a satellite around another body). The difficulty to recognize gravity as an alternative expression of the “regular” dynamical interaction was the erroneous value of Newton’s gravitational constant, being calculated as 40 orders of magnitude lower than the universal value of the Unified-Physics gravity factor.
