The Nature of Dark Energy and Dark Matter

Abstract

It is proposed that the accelerating expansion of the universe is due the cosmologicalization of the principle of equivalence - which recognizes momentary equivalence between gravitational force and inertial force - in an expanding spherical distribution of matter, wherein momentary equivalence occurs at a certain radial distance between gravitational force upon the gravitational mass and inertial force - generated by the accelerating frame of reference of spacetime - upon the inertial mass of an object on the surface of the sphere. The principle of equivalence also recognizes momentary equivalence between a freefalling gravitational mass and the impression of acceleration of an inertial mass in an inertial frame of reference with respect to an accelerating frame of reference. Since the acceleration of the inertial mass is impressional, it is conceivable therefore that the inertial mass of the object can be impressional as well. It is proposed that there are objects in nature which possess impressional inertial mass, and that such objects are the dark matter in the universe.
