Rotation of galaxies and dark matter

In a previous paper by the author was proposed a new metric for the gravitational field of a thin rotating disk physically different from the Kerr metric. The metric is admissible for any angular momentum of the disk. As demonstrated in the present paper the parameter determining the angular momentum of the Milky Way greatly exceeds its gravitational radius so that the Kerr metric physically admissible only if the angular momentum is sufficiently small is completely inapplicable to the Milky Way. It is shown on the basis of the new metric that the rotation of the Milky Way plays a decisive role in the motion of satellites in its gravitational field. The effects due to the rotation can imitate the presence of hypothetical dark matter.
