Modifying Einstein’s General Relativity to Explain Dark Energy

In a paper to be published in the International Journal of Modern Physics, available online now here, Dr. David Wiltshire proposes a modification of Einstein’s General Theory of Relativity which helps explain the enigma of dark energy. As Dr. Wiltshire puts it, “dark energy is revealed as a mis-identification of gravitational energy gradients and the resulting variance in clock rates.” As part of his modification he establishes what he calls the Cosmological Equivalence Principle which addresses the so-called Mach Principle, which is one of the things that got Einstein working on general relativity originally. Mach’s Principle is nicely summarized here, in essence it relates your local frame of reference to that of the stars.
