The University of Ottawa (uOttawa) is challenging current theoretical models that suggest the universe is made of “ordinary matter, dark energy, and dark matter.”
There is no room for dark matter in the universe, according to a new study from the University of Ottawa.
“In cosmology, the term ‘dark matter’ refers to anything that does not appear to interact with light or electromagnetic fields, or that can only be explained by gravity. We cannot see it and it is “We don’t know what they’re made of, but it helps us understand how galaxies, planets, and stars behave,” the university explained in a news release Friday.
The new discovery “challenges the common understanding of the universe that about 27 percent of the universe is made up of dark matter, less than 5 percent is normal matter, and the rest is dark energy,” Ottawa added. .
What led uOttawa to this new conclusion?
To reach this conclusion, Rajendra Gupta, a professor of physics in the Faculty of Science, combined two theories to create a new model, the university said. The two theories are Co-varying binding constants (CCC) And “I’m tired.” light” (TL), the new model is (CCC+TL model).
“This model combines two ideas: how the forces of nature diminish over time in the universe, and how light loses energy as it travels long distances. “This finding is consistent with several observations, including how galaxies spread and how light from the early universe evolved,” Ottawa said in a news release.
Dr. Gupta refutes the need for dark matter to prove her new model.
“The results of this study are consistent with our previous study (“Early Universe Observations by JWST and ΛCDM Cosmology”) Since the age of the universe is about 26.7 billion years, we now know that dark matter is not necessary for the existence of the universe,” said Gupta.
“Standard cosmology says that the accelerating expansion of the universe is caused by dark energy, but in reality it’s not due to dark energy, but rather to natural forces that weaken as the universe expands.”
Gupta further explains this by referring to “redshift,” which occurs when light shifts toward the red part of the spectrum. Researchers at the university interpreted data from a recent paper on the “distribution of galaxies at low redshifts and the angular size of the literature’s sound horizon at high redshifts.”
Professor Gupta said that while there are studies that question the existence of dark matter, his work “eliminates its cosmological existence while being consistent with important cosmological observations that we have seen over time.” “This is the first study to do so,” he added.
the study, Testing the CCC+TL cosmology with observed baryon acoustic vibration signatureswas published Friday in the peer-reviewed Astrophysical Journal.
