DECELERATION PARAMETER Q(Z) IN FOUR AND FIVE DIMENSIONAL GEOMETRIES, AND IMPLICATIONS OF GRAVITON MASS IN MIMICKING DE IN BOTH GEOMETRIES 1

Abstract

The case for a four dimensional graviton mass (non zero) influencing reacceleration of the universe in both four and five dimensions is stated, with particular emphasis upon if four and five dimensional geometries as given below give us new physical insight as to cosmological evolution. The author finds that both cases give equivalent reacceleration one billion years ago which leads to an inquiry if other criteria as to cosmology can determine the benefits of adding additional dimensions to cosmology models
