From Infinitely Small to Infinitely Great

During his career in physics, Albert Einstein tried hard to elaborate a theory that allows to unify the quantum mechanics with the celestial mechanics, therefore he published the general relativity in order to establish a link between the special relativity and the Newton’s gravitational law with the insight that gravity is not a force but rather a manifestation of curved space and time, which is produced by the mass-energy content of the space-time. But this theory has several flaws, especially when we try to explain the rotation of the moon around the earth, because we cannot represent a curved space created by the earth that allows the moon to gravitate, on the other hand Einstein did not accurately explain how the curved space is implicated in the mechanism of the earth’s rotation around its axis that has the same direction as the earth’s revolution around the sun, which makes it hard to explain the phenomenon of gravity with the general relativity, however it is obvious that gravity is the consequence of the creation of the universe, which means that the best way to define the origin of gravity, is the study of the transition from infinitely small to infinitely great.
