ABSTRACT: Staying on Earth, we do not perceive the 8 km/s velocity of its surface rotation, neither the 20 km/s revolution velocity around the Sun, nor the 200 km/s around the center of the Milky Way, which is apparently fixed in the center of our Universe. From the Earth, Hubble has observed a number of galaxies that are moving away from us at spectacular increasing speeds proportional to their distance. Due to the million light-year distances, the movie observed dates back an equivalent time lag, but shows the expansion of the Universe contrary to the contraction required by Gravity attraction. Lacking a justification, somebody imagined the existence of some mysterious dark energy contrasting Gravity, whose nature, after Galileo, Newton, and Einstein, is not completely known. Now that the action of Gravity has been disclosed, the expansion of the Universe is no longer a mystery.
