Ottawa, Canada – A new study from the University of Ottawa challenges the prevailing understanding of the universe by proposing a model that eliminates the need for dark matter. Published in The Astrophysical Journal, the research suggests that the current theoretical model, which includes normal matter, dark energy, and dark matter, may need revision.
In cosmology, dark matter is a concept used to describe matter that does not interact with light or the electromagnetic field, and can only be explained through gravitational force. While dark matter is unseen and its composition remains unknown, it plays a crucial role in our understanding of celestial bodies’ behaviors, such as galaxies, planets, and stars.
Professor Rajendra Gupta, from the University’s Faculty of Science, utilized the covarying coupling constants (CCC) and “tired light” (TL) theories to develop a new model that challenges the existence of dark matter in the universe. This CCC+TL model suggests that the expansion of the universe is not driven by dark energy as commonly believed, but rather by the weakening forces of nature as space expands.
By analyzing data on the distribution of galaxies at different redshifts, Gupta’s research provides evidence for a cosmological model that does not rely on dark matter for its existence. This groundbreaking study is the first of its kind to eliminate the cosmological significance of dark matter while aligning with key observations in the field.
Gupta’s findings bring into question the traditional view that dark matter makes up a significant portion of the universe. Instead, the study offers a new perspective on cosmic expansion and acceleration, challenging previous assumptions about the role of dark energy.
The implications of this research go beyond astrophysics, opening up new avenues for exploring the fundamental properties of the universe. By presenting an alternative cosmological model that negates the need for dark matter, Gupta’s work paves the way for further investigations into the mysteries of the cosmos.
The study, “Testing CCC+TL Cosmology with Observed Baryon Acoustic Oscillation Features,” published in The Astrophysical Journal in 2024, marks a significant advancement in our understanding of the universe’s composition and evolution. Further research and observations in this field are likely to build upon Gupta’s work and shed more light on the enigmatic nature of the cosmos.
