Resumen
One of the greatest challenges of science is to understand the current accelerated expansion of the Universe. In this work, we show that byconsidering the quantum nature of the gravitational field, its wavelength can be associated with an effective Compton mass. We proposethat this mass can be interpreted as dark energy, with a Compton wavelength given by the size of the observable Universe, implying that thedark energy varies depending on this size. If we do so, we find that: 1.- Even without any free constant for dark energy, the evolution of theHubble parameter is exactly the same as for the LCDM model, so this model has the same predictions as LCDM. 2.- The density rate of thedark energy is Ω_(Λ) = 0.69which is a very similar value as the one found by the Planck satellite Ω_(Λ) = 0.684. 3.- The dark energy has thisvalue because it corresponds to the actual size of the radius of the Universe, thus the coincidence problem has a very natural explanation. 4.-It, is possible to find also a natural explanation to why observations inferred from the local distance ladder find the value H_(0) = 73km/s/Mpcfor the Hubble constant. We show that if we take the variability of the dark energy into account, they should measure H_(0) = 67.3km/s/Mpcas well. 5.- In this model the in ationary period contains a natural successful graceful exit.
