Tentative explanation of the rotational velocity distribution in galaxies
The lack of flattening of the rotational velocities of stars in a given spiral galaxy has been one of the greatest unsolved problems in astronomy. While the velocities of the planets of our solar system can be explained by a simple Kepler system, this does not appear to be the case
when we examine the stars of a given galaxy. Looking at the planets in our solar system, we observe a decrease in rotational speed with increasing distance from the center, i.e., the Sun. Various hypotheses have been formulated to solve the problem of the missing decrease in the orbital velocity
of a star as a function of its distance to the center of the respective galaxy. Large quantities of dark matter (the so-called halos of dark matter) have been assumed to exist around the galaxy to explain the movements of stars in the galaxy while retaining Kepler's laws. A modification of
the Newtonian force-acceleration relationship has also been postulated (known as the MOND hypothesis). Here, an alternative explanation is proposed based on the assumption that stars, in contrast to planets, represent electrically charged bodies rather than electrically uncharged bodies. This
assumption can be used to explain the observed velocities of stars.
