Dark matter or strong gravity?

TL;DR

This paper proposes a modified gravitational potential with a logarithmic term that could reduce or eliminate the need for dark matter and explains the success of MOND at galactic scales.

Contribution

It introduces a modified Newtonian potential with a logarithmic component, offering an alternative to dark matter explanations in galactic dynamics.

Findings

Logarithmic potential reduces dark matter necessity

Explains MOND's effectiveness at galactic scales

Suggests possible origins for the modified potential

Abstract

We show that Newton's gravitational potential, augmented by a logarithmic term, partly or wholly mitigates the need for dark matter. As a bonus, it also explains why MOND seems to work at galactic scales. We speculate on the origin of such a potential.
