Dark Matter and Dark Energy Don’t Exist, New Study Claims
For many years, scientists have thought that dark matter and dark energy make up most of the cosmos. A new study, however, challenges that long-held belief by proposing that these mysterious components might not exist at all. Instead, what appears to be dark matter and dark energy could actually result from the gradual weakening of the universe’s fundamental forces as it grows older.
The research, led by Rajendra Gupta, an Adjunct Professor in the Department of Physics at the University of Ottawa, suggests that if the core strengths of nature’s forces (like gravity) change slowly across time and space, they could account for the puzzling behaviors astronomers see—such as how galaxies rotate, evolve, and how the universe continues to expand.
“The universe’s forces actually get weaker on the average as it expands,” Professor Gupta explains. “This weakening makes it look like there’s a mysterious push making the universe expand faster (which is identified as dark energy). However, at galactic and galaxy-cluster scale, the variation of these forces over their gravitationally bound space results in extra gravity (which is considered due to dark matter). But those things might just be illusions, emergent from the evolving constants defining the strength of the forces.”
He adds, “There are two very different phenomena needed to be explained by dark matter and dark energy: The first is at cosmological scale, that is, at a scale larger than 600 million light years, assuming the universe is homogeneous and the same in all directions. The second is at astrophysical scale, that is, at smaller scale the universe is very lumpy and direction dependent. In the standard model, the two scenarios require different equations to explain observations using dark matter and dark energy. Ours is the only one that explains them with the same equation, and without needing dark matter or dark energy.”
