A group of theoretical astronomers has carefully studied a fictitious type of dark matter that combines to form dark atoms. They discovered that the presence of dark atoms could have a significant impact on how galaxies evolve.
Most of the matter in the universe is unknown to us. We call it "dark matter," but it's all we can think of. As we understand it, dark matter consists of a whole new type of particle not yet understood by conventional physics.
Whatever this particle is, it only interacts with other objects through gravity, not with light or normal matter.
We have a lot of room for movement in our theoretical models because we do not fully grasp this enigmatic element. According to some of these models, the dark matter of the universe may not consist of a single type of particle. Instead, it may consist of many different types of particles. In addition to the four we know of, there may be other natural forces that interact specifically with dark matter particles.
According to this model, dark atoms, molecules and other more complex structures can be created when various dark matter components come together. The most important feature in these theories is that dark matter can be clustered quite tightly.
This fact was used by a group of researchers to investigate the observational implications of these dark models of atoms using simulations of the evolution of galaxies.
They discovered that atomic dark matter could rapidly coalesce to form a "shadow disk" in addition to the galaxy's normal stellar disk. From that moment on, dark atoms continue to come together to form structures similar to dark stars and dark black holes. It can even quickly enter the galaxy's core, where it rapidly increases the density.
At cosmological scales, none of these effects of atomic dark matter would be apparent. However, they will have a significant impact on the galaxy's stellar evolution. Matter collapses into stars, and any gravitational influence can alter the course of star formation.
According to the researchers, the amount and distribution of stars, as well as their rate of development, differ between galaxies with and without dark atoms. According to the researchers, these findings will help identify this enigmatic substance that rules our cosmos.
