标题： Rotation of galaxies and dark matter

摘要： 在作者之前的一篇论文中提出了一种新的度规，用于描述与克尔度规物理不同的薄旋转圆盘的引力场。 该度规适用于圆盘的任何角动量。 如本文所展示的，决定银河系角动量的参数大大超过其引力半径，因此仅当角动量足够小时才在物理上适用的克尔度规完全不适用于银河系。 基于新度规表明，银河系的旋转在其引力场中卫星的运动中起着决定性作用。 由于旋转产生的效应可以模仿假想暗物质的存在。 显示英文摘要

摘要： 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.
