Researchers have hypothesized that the universe contains “dark matter.” They have also posited the existence of “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 But according to a researcher at UNIGE, these concepts may be no longer valid, as universal phenomena can be demonstrated without them. This research exploits a new theoretical model based on the scale invariance of empty space. This research is reported in The Astrophysical Journal.
