ABOUT THE AUTHOR: María José T. Molina is the author of all the Molwick publisher books. With over 40 million visitors and two million books downloaded in PDF format from the website molwick.com, she is surely one of the most widely read authors in Spanish of scientific essays in the current millennium. DESCRIPTION: Avoiding where possible the use of mathematics, Global Dynamics develops Global Mechanics' model about the structure of matter regarding the relations between mass and movement or velocity and its variation or acceleration. The theories of Relativity and Quantum Mechanics describe motion but not the causes for it. Einstein s General Relativity tries to add some causes, such as the geometric effect of the space-time continuum. The fact that light deflects in a gravitational field exactly doubly so than mass according to Newton s Law of Universal Gravitation, made me suspect that some special relationship between the causes of both deviations must exist. While Einstein s Theory of Relativity uses kinetic energy to alter space-time and balance the planetary orbits; the Theory of Global Equivalence finds an additional force or second component of atractis causa, adjusted also by kinetic energy, to explain the physical reality without altering it. The Global Gravity Law deserves special mention for implying a different explanation, which is consistent with common sense, for the decisive predictions of the General Theory of Relativity by means of a small adjustment to Newton s Law of Gravity. I am referring to the effect of the gravitational lens, the gravitational red shift of light and the precession of the perihelion of Mercury.
