The Expansion of Spacetime

Authors: A. J. Owen

In this paper, the physical universe is modelled as an expanding Minkowski space, and this obviates the need for dark energy to be included in the cosmological model. The observed accelerated expansion in the current epoch can be understood purely on the basis of a mass-dominated universe, where deceleration due to gravity is more than compensated for by expansion of the time dimension. In the epoch prior to this, when a linear expansion of the scale factor occurred, the universe was radiation-dominated, and in the very early exponentially expanding universe, cosmic inflation can be attributed to an expanding ensemble of non-interacting particles. This is very different behaviour from that deduced from the currently accepted cosmological model.
