An earlier elaborated model of the expanding universe with its contents of dark energy, dark matter and normal matter is reconsidered and extended. The model is found to be reconcilable with the observed cosmical dimensions and with the magnitude of the present accelerated expansion. It has the form of a freely expanding cloud of zero-pointenergy photons, with the inclusion of a small amount of normal matter. On a macroscopic scale, within the radius of the observable universe, the model has the character of a flat Euclidian geometry, without the need of introducing curved space effects due to General Relativity. This flat geometry is found to be stable with respect to expansive and compressive perturbations, thus suggesting the universe to possess an intrinsic mechanism which aims at flat geometry.
