We had studied Einstein’s Theory of General relativity starting from elementary phenomena, together with the Galileo's principle on free fall of bodies that represent his precondition. We underlined the discrepancy of Galileo's principle, as the mass of the test body is not being subtract from the mass of the earth, and because the reciprocal attraction between the bodies has not been evaluated. Furthermore, we highlight that the free fall takes place along radial vertical lines that are not parallel. Finally, we verify the consequence of the shape of solid bodies for Galileo's principle and Einstein's theory, Archimedes' principle and the weighing (mass) of the bodies. Starting from elementary phenomena we study Einstein's theory of general relativity, together with Galileo's principle on free fall of bodies that represent his precondition. Galileo's principle estimates that all objects fall at a constant acceleration due to gravity regardless of their mass. On the contrary, we establish the non-effectiveness of that Galileo's principle as the mass of the test body is not being subtract from the mass of the earth (incorrectly thought to be constant) and moreover for not having been evaluated the reciprocal attraction of the bodies (superposition of effects). Likewise, we highlight that the free fall takes place along radial vertical lines that are not parallel. We study the shape of solid bodies, for which bodies that have the same mass but different shape (except from sphere, equilateral cylinder and cube) when varying their position on the reference plane they have different weight: a body a mass, a body infinite weight. Therefore, we verify the consequence of the shape of solid bodies according to the Galileo's principle (that is not effective) and for the confutation of Einstein's theory, Archimedes' principle and the weighing (mass) of the bodies.

Empezando por los fenómenos elementales se estudia la teoría de la relatividad general de Einstein, junto con el principio de Galilei sobre la caída libre de los cuerpos que es la presuposición. El principio de Galilei establece que todos los cuerpos, independientemente de su masa, caen con la misma aceleración de la gravedad. En cambio, notamos la inexistencia de este principio de que Galilei no haya deducido la masa del cuerpo de prueba de la de la tierra (considerada erróneamente constante), tampoco para evaluar la atracción mutua de cuerpos (efectos superpuestos). Además, debe se evidencia que la caída libre se produce de acuerdo con líneas verticales radiales que no son paralelas. Se estudia la forma de los cuerpos sólidos, de modo que los cuerpos que tienen la misma masa pero forma diferente (con la excepción de la esfera, el cilindro equilátero y el cubo) al variar de la posición sobre el plano de referencia tienen peso diferente: un cuerpo, una masa, un corpo infinitos pesos. Por lo tanto, se determinan las consecuencias de la forma de cuerpos sólidos para el principio de Galilei (que no es válido) y para la refutación de la teoría de Einstein, para el principio de Arquímedes y para el peso (masa) de los cuerpos.
