Gravity, where does it come from? (original) (raw)

Einstein's theory of general relativity describes the gravitational field around massive objects (like Earth) as a curvature in the spacetime. But it leaves the following question unanswered; why is the spacetime curved by a mass? Through a theory that has been introduced recently, regarding a medium for a light propagation, a simple answer is introduced. It depends on redefining the rest energy for a massive object (like a planet) as new form of kinetic energy. For a static and spherically symmetric object, with a specific radius(í µí±Ÿ í µí±œ), I have found that this kinetic energy is í µí±Ÿ 0 í µí± 2 í µí±£ 0 2 2í µí°º = í µí±€í µí± 2 , where (M) is the object's mass, and (í µí±£ í µí±œ) is a new term defined as rest speed of this object. The value of this rest speed determines the curvature of spacetime around the object. The results which are obtained are similar to Schwarzschild solution of Einstein's field equations.
