Presented is a theory in fundamental theoretical physics that establishes the relationship between time and energy. This theory abandons the concept that mass is directly affected by relativistic motion and shows instead, that the energy related to an object undergoing such motion is a direct result of the effect time expansion has on velocity. In support of this concept, new equations are introduced for both kinetic and total energy that replace those of special relativity. Subsequent equations for momentum, distance, and acceleration are then derived that establish a direct link between the time and energy theory and the principles of an earlier theory, the millennium theory of relativity. A final consequence of this theoretical analysis ...
