Recently, a study led by Bernard Rizk from the University of Ottawa published a disruptive discovery in the Astrophysical Journal. This research makes a surprising point: there is no dark matter in our universe.
Traditionally, the universe was thought to be composed of ordinary matter, dark energy, and dark matter. “Dark matter” is a mysterious substance that does not interact with light or electromagnetic fields and can only be explained through the effects of gravity. We can’t see it and don’t know what it’s made of, but it helps us understand the behavior of galaxies, planets and stars.

However, physics professor Rajendra Gupta used two theories – covarying coupling constants (CCC) and “tired light” (TL) theory (CCC+TL model) to reach this conclusion . This model combines the idea that natural forces weaken over cosmic time and that light loses energy during its long journeys. It has been confirmed to be consistent with several observations, for example on the distribution of galaxies and the evolution of light in the early universe.
The discovery challenges the popular understanding of the universe, which states that about 27% of the universe is made up of dark matter, less than 5% is ordinary matter, and the rest is dark energy.
“Our previous work has shown that the universe is 26.7 billion years old, which led us to discover that the universe does not need dark matter to exist,” Gupta said. In standard cosmology, the accelerated expansion of the universe is thought to be caused by dark energy, but It’s actually due to the weakening of natural forces as the universe expands, not dark energy.

The study also proposes a new model to explain the redshift of distant objects. He analyzed data on the distribution of low-redshift galaxies and the angular size of sonic horizons in the high-redshift literature.
“There have been several papers questioning the existence of dark matter, but to my knowledge, my paper is the first to eliminate its cosmological existence in a way that is consistent with key cosmological observations that we have confirmed,” Gupta said. If dark matter is considered so important and there is overwhelming evidence for its existence, how did Gupta prove that it doesn’t exist? The answer lies in combining two theories about the universe: the covariant coupling constant and the exhausted light.
This research covers many fields from star formation, sonic horizons, cosmic microwave background radiation, etc., and even proposes to solve the mystery of galaxies that could not exist in the early universe, and reaffirms previous research that the age of the universe is ours. Twice what was previously thought. While the research isn’t perfect, scientists have long dismissed the “tired light” theory as fringe science.
However, the research remains solid. At the very least, it highlights an obvious fact: The standard model of the universe is flawed, and we need a new one. As new technologies emerge that allow us to study space like never before, perhaps new models are on the horizon.
The relevant research was published in the latest issue of The Astrophysical Journal.
