Hungarian scientists prove that mysterious dark energy accounting for 68% of the universe may not exist.
Scientists at Eotvos Loránd University, Hungary, conduct research showing that the current standard models of the universe do not take into account its changing structure. If you consider this factor, mysterious dark energy that is thought to make up 68% of the universe may not exist, Science World Report on April 4 reported.
From the 1920s, the scientific community began to chart the velocities of galaxies. They conclude that the entire 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, analyzing something mysterious that contributed to the movement of stars located in galaxies. . Currently, dark matter is believed to make up 27% of the universe and ordinary matter only 5%.
By the 1990s, scientists assumed that the universe had a third constituent of 68% after observing white dwarfs exploding in binary star systems. It is dark energy, the factor that accelerates the expansion of the universe.

Gabor Racz, lead author of the study, and colleagues questioned the existence of dark matter and proposed another explanation. According to the team, conventional cosmic models are based on approximation and do not take into account its structure. Furthermore, matter is assumed to have a homogeneous density. They recreated the evolution of the universe using computer simulation, looking at the effect of gravity on the distribution of millions of dark matter particles.
“Our finding is based on a mathematical hypothesis that allows for different expansion of the universe, consistent with general relativity. It shows how the formation of complex structures of matter causes. These problems have previously been ignored, but their account may explain cosmic expansion without the need for dark energy, “said László Dobos, co-author of the study. , to speak.
