Universe is no older than 27 billion years and there is nothing like dark matter: Study

In a new study, scientists have claimed that the Universe is only 27 billion years old and does not have any dark matter. 

The study was conducted by Rajendra Gupta, professor of physics at the University of Ottawa. Gupta suggested that dark matter or dark energy might not be required to explain the workings of the universe. 

The research of the professor is based on a model that combines two theories: “tired light” (TL) and covarying coupling constants (CCC).

The CCC theory challenges the idea that things like the speed of light or the charge of an electron are fundamental constants of nature that do not change.

However, if the CCC theory is right, it changes the understanding of everything that is present in the universe.

According to the “Tired Light” idea, light loses energy across long distances, which causes redder wavelengths and does not require the universe to expand.

When these two models are placed together, they provide a new framework for understanding cosmic phenomena.

According to the findings of Gupta, the new model changed the facts about the universe.

“The study’s findings confirm our previous work, which suggested that the universe is 26.7 billion years old, negating the necessity for dark matter’s existence,” Gupta explained

“Contrary to standard cosmological theories where the accelerated expansion of the universe is attributed to dark energy, our findings indicate that this expansion is due to the weakening forces of nature, not dark energy,” he added.

A major part of the research carried out by Gupta focused on “redshifts" in which light stretches to the red end of the spectrum while travelling through space.

After analysing data on the distribution of galaxies at low redshifts and the patterns seen in the early universe at high redshifts, he claimed that dark matter did not exist.

“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 that we have had time to confirm,” Gupta explained.
