Dark Matter and the Dynamics of Galaxies: a Newtonian Approach

Authors: Mugur B. Răuţ

In this paper I propose a correction to the well-known Newtonian gravitational potential, a correction which explains the form of the radial velocities as a function of the discoid galaxies radii. The main scope of this work is to find a correction to the Newtonian gravitational potential which has to fulfil two major conditions: a) to take into account the entire amount of the experimental data; b) the resulting potential to be a consequence of condition a) from a physical perspective. As a result, the corrected form of the Newtonian gravitational potential was found to belong to a physical cause and this cause can be the existence of the dark matter, evenly distributed within galaxies. This distribution makes dark matter to act as a binder for ordinary matter, so that the discoid galaxies not rotate as a fluid (as standard Newtonian theory states), but as some rigid frames (as the observational data state).
