The fact that the fundamental theories of physics were completed well before any significant knowledge about the real universe and its enormous gravity was available necessitates a re-examination of these theories, especially that of dynamics and relativity. The results of this analysis, along with several experimental facts, reveal that the matter frame of the universe provides a preferred absolute frame and that its gravity determines the laws of motion. In a grand generalization of Machian thought, Newton’s law of motion arises as a relativistic gravitational effect, the equivalence principle as a natural consequence of the gravitational effect in the massive universe, and the entire relativistic modification of rates of atomic clocks as a gravitational time dilation with absolute velocity as the key factor instead of relative velocities. These ideas of ‘Cosmic Relativity’ unify kinematics and dynamics, answering outstanding fundamental questions. Compelling experimental evidence involving simple configurations of magnets and charges in relative motion reveals new aspects of electrodynamics that point to new relativity. Two experiments that examine the one-way relative speed of light clearly reveal the first order Galilean anisotropy predicted by Cosmic Relativity, invalidating the hypothesis of the invariance of the relative one-way speed of light, the fundamental principle underlying the present paradigm of physics. This necessitates a paradigm change in which gravitational influence of the matter filled universe determines laws of motion, dynamics and the physics of relativity.
