questioned the existence of the most mysterious substance of the universe

Dark matter and dark energy can explain the movement of stars and the accelerating expansion of the universe, but their presence has not yet been directly observed.

Several studies have been conducted on the most mysterious substances in the universe, but a new study suggests they may not exist at all.

Using a new model, a scientist in astrophysics found that the behavior of the universe can be explained without the need for dark matter or dark energy, and argues big theories, including Einstein and Newton.

It is believed that nearly 70% of the universe consists of dark energy, which led to its rapid expansion, dark matter is believed to account for 27% of it.

In a new study published in the journal Astrophysics, Professor André Maider said that stability in volume should be taken into account. This can challenge the common understanding of physics, and what happened after the Big Bang.

"In this model, there is the starting hypothesis that was not taken into account, in my own opinion, and by that I mean the stability of the size of the empty space, in other words, the empty space and its properties do not change yet," said Meider, emeritus professor of astronomy at the Faculty of Science at the University of Geneva. Expansion or contraction ".

According to Einstein, empty space works on the basis of what is known as the cosmic constant, and everything else depends on it, says Meider.

Instead, the researcher used a model based on the stability scale, and found that cosmic tests matched observations. The tests showed that the modified law could explain the high velocities of galaxies and stars in the outer paths of the galaxy.

The controversial results suggest that the standard model should be reviewed. The researcher explains that there is an urgent need to do more tests before confirming the results.

This is not the first time scientists have suggested that dark matter and dark energy may not exist after decades of research.

Another study, published earlier this year, showed that traditional models failed to address the changing structure of the universe, which meant that rapid expansion could occur without the need for dark energy. But controversial assumptions often receive a violent reaction.
