Scientists have confirmed that the dark matter-dominated model of the Universe is still correct, although not everyone agrees.
Astrophysicists use dark matter to explain anomalies observed in the Universe. Unlike ordinary matter, dark matter does not emit, absorb or reflect light; This makes it invisible and detectable only through the gravitational effect. New analysis of space observations and created simulations have enabled astrophysicists to confirm the existence of an elusive component of the Universe. The results of the research were published in the journal Monthly Notices of the Royal Astronomical Society, Earth writes.

Scientists are investigating whether the universe can be fully explained by matter that can be directly seen and measured, or whether dark matter is necessary to explain otherwise unexplainable observations.
Many astrophysicists now believe that dark matter is necessary to explain the behavior of stars and galaxies. According to the study’s authors, they showed how actual observed relationships can be used as the basis for testing two different models to describe the universe. That is, with and without dark matter.
Scientists analyzed observations of space and created simulations that took both ordinary and dark matter into account. Using simulations, scientists recreated features observed in real galaxies that are difficult to explain without dark matter. The results show that these properties are indeed consistent with those expected in a universe containing dark matter. Therefore, astrophysicists believe that the dark matter model of the universe is the best description of the Universe.
Scientists have also examined the relationship between visible matter and the suspected presence of dark matter in galaxies. The observed galaxies appear to fit the close relationship between ordinary matter and hypothesized dark matter. Although some scientists believe that what is confused with dark matter is evidence that the current theory of gravity is wrong.
According to scientists, dark matter not only predicts the relationship, but can also explain what is seen in observations for many galaxies, and is more natural than the modified theory of gravity suggests.
Interestingly, the observations confirming these properties were originally made by supporters of the theory that dark matter does not exist in the Universe.
According to the authors of the study, when stars are born and die, they explode and form supernovae that can form the centers of galaxies, which naturally explains the existence of these features. In other words, the properties that scientists examine require taking into account both the existence of dark matter and the physics of ordinary matter.
Now astrophysicists want to see whether the same relationship can be used to distinguish between different models of dark matter. Understanding how the relationship changes under different dark matter models could help understand the properties of dark matter.
As I already wrote FocusThere are black holes in the universe that cannot die. Astronomers are trying to solve the mystery of primitive black holes that have not yet been detected by any detector.
Moreover Focus He wrote that CERN had solved the riddle of particle physics. Physicists have discovered the first evidence of CP symmetry violation in the decay of a strange B meson.
