A groundbreaking study from the University of Ottawa has shaken up the current model of the universe by suggesting that dark matter may not actually exist. Professor Rajendra Gupta, from the Faculty of Science, utilised a novel combination of theories to reach this thought-provoking conclusion.
In the traditional cosmological framework, dark matter is believed to constitute a significant portion of the universe, playing a crucial role in shaping the behavior of celestial bodies. However, the new research challenges this notion, proposing a different explanation for the observed phenomena.
Gupta's innovative approach, which combines covarying coupling constants (CCC) and "tired light" (TL) theories, has not only raised questions about the need for dark matter but has also garnered support from various cosmological observations. This suggests that the universe may operate differently than previously thought, potentially reshaping our understanding of its fundamental properties.
"This study's findings confirm that the universe does not require dark matter to exist, challenging the prevailing understanding in standard cosmology," affirms Gupta. "The accelerated expansion of the universe, often attributed to dark energy, may actually be a result of weakening forces of nature as it expands, rather than the influence of dark energy."
The study's methodology involved a meticulous analysis of data from recent papers on the distribution of galaxies at low redshifts and the angular size of the sound horizon in the literature at high redshift. Gupta emphasized the significance of this research, stating, "There are several papers that question the existence of dark matter, but mine is the first one, to my knowledge, that eliminates its cosmological existence while being consistent with key cosmological observations."
