Researchers have hypothesized that the universe contains a 'dark matter.' They have also posited the existence of a 'dark energy.' These two hypotheses account for the movement of stars in galaxies and for the accelerating expansion of the universe. But, according to a researcher, these concepts may be no longer valid: the phenomena can be demonstrated without them. This research exploits a new theoretical model based on the scale invariance of the empty space.
