A new theory about the structure of the Universe

Presented here is a new cosmology. It is shown how the time and space transformations due to the relative velocity between two observers can be fully explained by the gravitational effect of mass and energy in an expanding Universe. It defines the kinetic energy, and potential energy, of the expanding Universe. It includes an integration between General Relativity and Quantum Mechanics in a consistent and satisfying way. We see why inertial mass and gravitational mass are equivalent.
