Quantum Standpoint for a More Understandable Universe

The study implements the concept of space-time quantum uncertainty to outline a possible model of universe. Simple considerations show that the relativistic equations inferred as a consequence of the uncertainty allow describing effects typically expected in the frame of quantum phenomena, e.g., the fluctuations. These results contribute to clarify issues today still open, like the dark energy, the inflationary expansion of the universe and the possible existence of antigravity.
