It would look like our galaxy without dark matter?

Dark matter — a mysterious invisible substance that have a huge impact on the evolution of galaxies in the Universe. Despite the fact that mysterious “something” is absolutely not interact with the electromagnetic energy of the world around us might look like in a completely different way. As the portal phys.orgresearchers from the Bonn University for the first time were able to simulate the formation of galaxies in the Universe without “dark” matter. In order to reproduce a similar process on the computer, the scientists had to modify all the usual laws of gravitation of Newton, and though a galaxy created with the help of computer calculations similar to those we see today between real objects and galaxies without dark matter , there are a number some differences. So what can help an unusual study for modern cosmology, still puzzled over the nature of dark matter?

How did dark matter?

When the result of the Big Bang matter spread through the Universe, its intensity was not distributed in space uniformly. Larger clusters of matter was drawn to the smaller pieces, eventually forming the gas clusters and then galaxies. Important part of the history of the universe is the so-called dark matter, which may be responsible for the initial uneven distribution of matter. This assumption also explains some puzzling observations that scientists attribute semi-mystical substance. For example, the stars in spinning galaxies often move with such incredible speed that without the participation of a certain “star putty” they simply have thrown off their stellar “brothers”. In this case, the role of space “handler” can qualify an additional source of gravity, which can’t be seen through a telescope — the mysterious dark matter.

Due to the fact that direct evidence of the existence of dark matter is still there, researchers from the Institute for radiation and nuclear physics.Helmholtz of Bonn University have decided to create a model of the Universe without the participation of a mysterious substance gluing of the galaxy. According to their hypothesis, the attraction between two massive objects obey Newton’s laws only to a certain point. For small accelerations that exist in galaxies, the total force of gravity is greatly increased, which leads to the fact that large stellar objects do not disintegrate during your rotation.

In order to test this theory, researchers used special software, allowing the modeling of the formation of stars and galaxies, starting from the primary gas clouds and ending with the processes occurring in the Universe a few hundred thousand years after the Big Bang. The researchers argue that their findings in many aspects surprisingly close to what scientists have observed with modern telescopes. In that case, perhaps dark matter not at all?
