The finding was discovered by Rajendra Gupta, a physics professor at the University of Ottawa, who has proposed a model that aims to explain the universe without dark matter or dark energy.
A new study revealed that dark matter does not exist in the universe, and it is around 27 billion years old. The study has challenged long-held ideas about the universe by proposing a model that does not require dark matter or dark energy, two concepts that have dominated modern cosmology for decades. An earlier study indicated that the universe is a mix of ordinary matter and two invisible components called dark matter and dark energy.
The finding was discovered by Rajendra Gupta, a physics professor at the University of Ottawa, who has proposed a model that aims to explain the universe without dark matter or dark energy. He argued that familiar assumptions might be holding back progress. “The study’s findings confirm that our previous work (“JWST early universe observations and ΛCDM cosmology”) about the age of the universe being 26.7 billion years has allowed us to discover that the universe does not require dark matter to exist,” explains Gupta.
Rajendra Gupta combines two ideas in his model: covarying coupling constants (CCC) and “tired light” (TL). The CCC concept questions whether fundamental constants, such as the strength of forces or the speed of light, might vary over time or across space, which could significantly alter our understanding of cosmic evolution, according to The Earth.com.
