📡 This model postulates that the Universe does not have dark matter, and respecting observations

The exact nature of the Universe is a question that fascinates and challenges scientists.

A study from the University of Ottawa, published in The Astrophysical Journalcalls into question the accepted composition of the Universe, which would include the black matter (In astrophysics, dark matter (or dark matter), translation from English…) in addition to matter (Matter is the substance that makes up any body having a tangible reality. Its…) ordinary andenergy (In the common sense, energy refers to everything that allows us to carry out work, produce energy, etc.) black. This new model, developed by Rajendra Gupta, professor of physique (Physics (from the Greek φυσις, nature) is etymologically the…)is based on the association of the theories of covariant coupling constants (CCC) and the “light (Light is all electromagnetic waves visible to the eye…) tired” (TL), referred to as the CCC+TL model.

The CCC+TL model posits that the forces of nature diminish with cosmic time and that light loses energy over long distances. This approach offers an alternative explanation for the distribution of galaxies (Galaxies is a quarterly French magazine devoted to science fiction. With…) and the evolution of light from the early Universe, without resorting to dark matter. This hypothesis contradicts the traditional view that the Universe is approximately 27% dark matter, with less than 5% ordinary matter, the remainder being dark energy. The study is based on the analysis of recent data on the distribution of galaxies at low shifts towards the rouge (The color red has different definitions, depending on the color system we use…) and on the angular size of thehorizon (Conceptually, the horizon is the limit of what we can observe, due to its own…) sound in the early Universe. These observations (Observation is the action of attentively following phenomena, without wanting to…)compared to the CCC+TL model, suggest that the Universe could be passer (The genus Passer was created by the French zoologist Mathurin Jacques…) dark matter to explain its expansion and structure.

This conclusion opens the door to a new understanding of the Universe, by calling into question the role attributed to dark matter and dark energy in its expansion. Instead, it puts forward the idea that this expansion could be due to the weakening of the forces of nature.

Gupta points out that this study confirms the results of previous work indicating that the Universe may be older than previously thought, reinforcing the idea that standard cosmology may need revision. His work represents a significant step forward in questioning the cosmological existence of dark matter, while being consistent with key cosmological observations.
