Where did the galaxy close to the milky Way

Around the milky Way there is quite a bit of spinning galaxies. Scientists today, thanks to computer modeling, believe that can explain this mystery. Created a computer model involves a much larger number, which caused some doubts concerning the correctness of the generally accepted theory of cold dark matter – a mysterious substance that cannot be seen and detected by instruments, but whose existence there is no doubt among scientists. It on all canons is the main material involved in the formation of new galaxies.

According to the new theories, feeling the force of gravity, particles of matter could interact in the young Universe with neutrinos and photons, which caused the scattering of dark matter.

In the early Universe, according to scientists, the clumps of dark matter captured by the intergalactic gas, is also involved in the formation of galaxies and new stars. However, due to the scattering of its particles, leading to abrasion of the structure, the ability of this could be significantly reduced, which also affected the formation of galaxies near the milky Way.

In addition to the current theory, there are alternative, therefore, there are real prerequisites for a new study of the interaction of particles with dark matter. The photo shows two images: left – the formation of small galaxies noninteracting dark matter, right – the situation when the interaction of matter with particles reduces the number of galaxies that could be nearby the milky Way.
