A Gravitational Explanation for the Flatness of Stars and Dust Velocities in Galaxies as an Alternative to Dark Matter

Abstract

Using recent proposed Maxwell’s equations for the gravitational field, it is shown that a gravitational field component of the form |R |~1/r appears formally. When this field is applied to a bulge-stars or bulge-dust motion within a Galaxy, the variable r means the distance of a star or dust to the bulge of the Galaxy, and this component of the gravitational field within a Galaxy can bring about the flatness behavior of the velocities of the stars or dust as a function of the distance of its bulge. This research offers an alternative to the dark matter hypothesis using a modified gravitational force.
