In the center of the Milky Way is a giant ball of dark matter, said Sergei Troitsky, an employee of the Institute for Nuclear Research of the Russian Academy of Sciences.
He outlined his theory in an article that was published in the Journal of Cosmology and Astroparticle Physics.
Many scientists agree that there is a black hole in the center of our Galaxy, the mass of which reaches 4 million times the mass of the Sun. But, according to Troitsky, this assumption is wrong. In addition, it has been repeatedly refuted by various astronomical observations.
The Russian scientist believes that in the center of the Milky Way there is not a black hole, but a ball of dark matter, which he calls a Q-ball. The existence of such a Q-ball resolves contradictions and explains many processes occurring in the Galaxy.
But scientists cannot yet check whether the Q-ball is located in the center of the Milky Way. But they hope that powerful telescopes will be launched in the next decade, which will allow to look even into the center of our Galaxy.
