Dark Matter in the Galaxy

In the world we are familiar with seeing, ordinary things are included. Everything consisting of atoms is considered normal. General substances make up 5% of all substances. So, what is the rest of 95%? Dark energy accounts for about 70% of our universe, and dark matter makes up the last 25%. What is Dark Matter Dark matter is the only explanation why our universe expands that way, but we do not know what it constitutes.

"We believe that each galaxy has dark matter and the dark matter is the beginning of the galaxy.This invisible strange substance is one of the most important aspects of every galaxy.The galaxy is It is effective and believes that dark matter is genuine, but in addition to the other components of the galaxy, it itself exists independently, "Dark Matter" is currently available to us "Can not see", and the only factor that proves its existence is its interaction with the gravity of normal matter. Nevertheless, it is believed to account for about 80% of the mass of the universe, and many theories suggest that dark matter is an integral part of the formation of galaxies.

The galaxy does not need many stars. Like 95% of the dark matter of our Milky Way galaxy, it may be ruled by dark matter. However, we know that the galaxy is as large as our galaxy, but it is almost completely dark matter. The name of this galaxy is Dragonfly 44, which is made up of 99.99% dark matter. Last year, when the dragonfly telescope noticed the sky area of ​​the Coma constellation, the galaxy was first discovered using WM Keck Observatory and Gemini North Telescope in Manuacare, Hawaii. Although it is relatively close to the Earth, this galaxy is very dim, so it has not been discovered by astronomers for many years

Michino Kaku, an American theoretical physicist, explained in a series that dark matter surrounds the aura around the galaxy, keeping the rotational speed of the galaxy constant and giving galactic mass (Rishwanm, 2008). The overall effect of the dark matter is that it attracts the scale of the Milky Way, increases the mass, thereby increasing the gravity to the center of these galaxies. The dark energy conceptualization of dark matter theory includes gravity, it is natural that expansion of the universe slowly stops and shrinks due to gravitational mechanics, or at least the expansion speed slows down. In contrast, scientists have measured the expansion rate of the universe and discovered that the expansion rate actually accelerates rather than slowing down.
