Abstract
In this paper I propose a quantum gravitational cosmological model which introduces a mass density function that reproduces the WMAP and the PLANCK missions' data quite accurately. This function implies that the Universe started with a mass equal to one half of the Planck mass, avoiding the need for a singularity (point with infinite mass density) at the beginning of (normal) time. One of the predictions of the model is that the mass of the Universe grew very rapidly according to an exponential function so that most of the mass of the Universe was “created” very early in its history (99 % of the mass of the Universe was created in the first 442 million years since the Big Bang). Because the average mass density function changes over time, this model is radically different to the Steady State Model. The model presented here assumes the existence of a Pre-universe, meaning that our Universe is not the result of a “creation process” but the result of a mysterious transformation. Finally, this formulation, which does not use General Relativity's field equations, encompasses part of the original Friedmann work. Therefore, we draw the conclusion that we don't need GR to develop an acceptable cosmological model.
