68% of dark energy in the universe may not exist

Hungarian scientists prove that mysterious dark energy accounting for 68% of the universe may not exist.

Scientists at the University of Eötvös Loránd, Hungary, conducted research to show that the current standard models of the universe do not take into account its changing structure. Considering this element, the mysterious dark energy is thought to account for 68% of the universe that may not exist, Science World Report reported on April 4.

From the 1920s, scientists began to chart the velocities of galaxies. They concluded that the whole universe is expanding and starting from a very small point.

In the second half of the 20th century, astronomers found evidence of invisible dark matter, by analyzing something mysterious that contributed to the movement of stars in galaxies. . Currently, people believe dark matter accounts for 27% of the universe and ordinary matter accounts for only 5%.

By the 1990s, scientists believed that the universe had a third component that accounted for 68% after observing white dwarfs exploding in binary star systems. It is dark energy, which promotes the process of accelerating the expansion of the universe.

Gabor Racz, the lead author of the study, and his colleagues questioned the existence of dark matter and proposed another explanation. According to the team, conventional cosmic models are based on approximations and do not take into account its structure. Moreover, the material is assumed to have uniform density. They recreate the evolution of the universe with computer simulations, considering the effect of gravity on the distribution of millions of dark matter particles.

"Our findings are based on a mathematical hypothesis that allows for different expansion of the universe, in accordance with general relativity. It shows how the formation of complex structures of matter causes These problems were previously ignored, but taking into account them can explain the process of expanding the universe without the need for dark energy , " László Dobos, co-author of the study. , to speak.
