The Principles of Self Creation Cosmology and its Comparison with General Relativity

Abstract

There are, at present, several gravitational and cosmological anomalies; the dark energy problem, the lambda problem, accelerating cosmological expansion, the anomalous Pioneer spacecraft acceleration, a spin-up of the Earth and an apparent variation of G observed from analysis of the evolution of planetary longitudes. These conundrums may be resolved in the theory of Self Creation Cosmology, in which the Principle of Mutual Interaction subsumes both Mach's Principle and the Local Conservation of Energy. The theory is conformally equivalent to General Relativity in vacuo with the consequence that predictions of the theory are identical with General Relativity in the standard solar system experiments. Other observable local and cosmological consequences offer an explanation for the anomalies above. The SCC universe expands linearly in its Einstein Frame and it is static in its Jordan Frame; hence, as there are no density, smoothness or horizon problems, there is no requirement for Inflation. The theory determines the total density parameter to be one third, and the cold dark matter density parameter to be two ninths, yet in the Jordan frame the universe is similar to Einstein's original static cylindrical model and spatially flat. Therefore there is no need for a 'Dark Energy' hypothesis. As the field equations determine the false vacuum energy density to be a specific, and feasibly small, value there is no 'Lambda Problem'. Finally certain observations in SCC would detect cosmic acceleration.
