The prevailing cosmic model divides the universe into three main components: 'normal matter,' 'dark energy,' and 'dark matter.' However, recent research from the University of Ottawa introduces a compelling argument against this framework, indicating a universe without the need for dark matter.
Dark matter, a substance hypothesized to account for approximately 27% of the universe's mass and energy, is invisible and does not interact with electromagnetic forces. Its existence has been inferred from the gravitational effects on visible matter and the cosmic microwave background radiation. Despite its elusive nature, dark matter is a cornerstone in our current understanding of the cosmos, providing explanations for the behavior of galaxies and the large-scale structure of the universe.
Rajendra Gupta, a distinguished physics professor at the University of Ottawa's Faculty of Science, utilized the covarying coupling constants (CCC) and "tired light" (TL) theories to formulate the CCC+TL model. This innovative model, through its integration of the concepts of diminishing natural forces over cosmic time and the energy loss of light over vast distances, aligns with numerous astronomical observations, including the distribution of galaxies and the evolution of early universe light.
The findings not only challenge the existing cosmic paradigm but also redefine our understanding of the universe's composition, significantly reducing the role of dark matter.
"Our analysis, especially in light of the data from recent observations, indicates that the universe's accelerated expansion can be attributed to the diminishing strength of nature's forces, rather than dark matter or dark energy," Gupta elucidates. He further emphasizes that this study, while building upon previous research, is unique in its comprehensive dismissal of dark matter's cosmological necessity, in alignment with critical observational evidence.
This revelation has the potential to revolutionize our comprehension of the cosmos, prompting a reevaluation of fundamental cosmological theories.
