Saed News: A new study from the University of Ottawa challenges traditional cosmological models, claiming that dark matter does not actually exist and that the age of the universe is about 27 billion years — nearly double previous estimates.
According to SAEDNEWS, while “dark matter” has long been considered a cornerstone of modern physics, the revolutionary hypotheses proposed by Dr. Rajendra Gupta may mark the beginning of a new era in our understanding of the origin, scale, and evolution of the universe.
According to Earth.com, the universe may appear simple at first glance: a collection of stars, gas, dust, and gravity holding everything together. But a closer look into deep space reveals a reality far more complex and mysterious.
For decades, the standard cosmological model has suggested that most of the universe is made of substances we cannot directly see or touch. According to this view, the cosmos consists of ordinary matter along with two invisible components known as “dark matter” and “dark energy.”
This framework has formed the foundation of textbooks, space missions, and cosmic maps, yet it has always faced difficult questions because dark matter and dark energy have never been directly observed or experimentally detected. After decades of unsuccessful searches, some scientists now ask: “How long should we continue searching for something that may not even exist?”
A bold new line of thinking takes these doubts seriously and suggests that perhaps the universe does not require these invisible components at all.
Dr. Rajendra Gupta, a professor of physics and astronomy at the University of Ottawa, has proposed a model aimed at explaining the universe without the need for dark matter or dark energy.
Gupta believes long-accepted assumptions may have slowed scientific progress. He states: “Our study confirms our earlier work estimating the age of the universe at 26.7 billion years, allowing us to conclude that the universe does not require dark matter to exist.”
Gupta’s approach combines two major concepts: “Covarying Coupling Constants” (CCC) and “Tired Light” (TL).
The CCC theory questions whether the so-called constants of nature — such as the strength of fundamental forces or the speed of light — may actually change over time or across space. Even tiny changes could fundamentally alter our calculations of cosmic evolution.
Meanwhile, the “Tired Light” theory offers a different explanation for redshift. In the standard model, the redshift of distant galaxies is interpreted as evidence of the expanding universe. However, the TL theory suggests that photons lose a small amount of energy while traveling vast distances, causing their light to shift toward red wavelengths.
Together, CCC and TL create a framework that attempts to explain cosmic signals without invisible matter.
The concept of dark matter did not emerge randomly. In the 1930s, astronomer Fritz Zwicky noticed that galaxy clusters moved in ways inconsistent with their visible mass. Later observations showed that galaxies rotate much faster at their outer edges than expected, as if additional gravity were present.
Gravitational lensing — the bending of light by mass — also suggests more gravitational pull than visible stars alone can provide.
According to standard calculations, dark matter makes up roughly 27% of the universe, while ordinary matter accounts for less than 5%. The rest is attributed to dark energy, a term used to explain the accelerating expansion of the universe. Under this model, the universe is estimated to be about 13.8 billion years old.
Gupta argues that if the forces of nature weaken over time, dark energy is no longer necessary to explain cosmic acceleration.
He also claims that major astronomical observations can be explained without dark matter if physicists allow constants to vary and accept that light loses tiny amounts of energy during its journey across space.
He explains: “Unlike standard cosmological theories that attribute accelerated expansion to dark energy, our findings suggest the expansion results from weakening natural forces rather than mysterious energy.”
A large part of Gupta’s research focuses on redshift analysis. His work compares nearby galaxies with patterns from the early universe observed at high redshifts.
The central claim is that these signals fit consistently within the CCC+TL model without requiring dark matter.
Gupta confidently states: “Many papers question dark matter’s existence, but as far as I know, my paper is the first to eliminate its cosmological necessity while remaining fully consistent with key observations.”
If the CCC+TL model survives rigorous testing, it could reshape much of modern cosmology. It may offer new explanations for the cosmic microwave background, galaxy formation timelines, and gravitational lensing.
It would also change how scientists interpret time and distance in space, since redshift would no longer solely indicate cosmic expansion. Most importantly, it challenges the standard Big Bang timeline.
Like all scientific theories, Gupta’s model must ultimately be tested against observations. It must successfully predict galaxy rotation curves, gravitational lensing maps, and patterns in the cosmic microwave background.
If physical constants truly vary, scientists should also detect traces of those changes in the atomic spectra of distant quasars.
Research teams are currently analyzing precise telescope data and high-resolution microwave maps to determine whether the universe supports these predictions.
Ultimately, two major questions remain: Were dark matter and dark energy simply mathematical tools used because we misunderstood changing physical constants? And is the universe far older than current estimates suggest?
Science advances only when theories meet evidence. Gupta’s study presents a bold alternative: a universe in which constants evolve, light loses energy over cosmic distances, and neither dark matter nor dark energy are required. Whether this idea survives will depend entirely on future measurements and observations.
