Is dark matter an extra-dimensional effect?

TL;DR

This paper explores the hypothesis that dark matter effects in galaxies could be explained by extra-dimensional forces influencing particle dynamics, suggesting a new perspective on galactic rotation curves.

Contribution

It proposes that dark matter phenomena may result from higher-dimensional space-time effects, introducing a new model of extra forces affecting particle motion without altering their intrinsic properties.

Findings

Extra forces from higher dimensions can modify particle trajectories.

Galactic rotation curve constancy may indicate extra dimensions.

The model offers an alternative explanation to dark matter for galaxy dynamics.

Abstract

We investigate the possibility that the observed behavior of test particles outside galaxies, which is usually explained by assuming the presence of dark matter, is the result of the dynamical evolution of particles in higher dimensional space-times. Hence, dark matter may be a direct consequence of the presence of an extra force, generated by the presence of extra-dimensions, which modifies the dynamic law of motion, but does not change the intrinsic properties of the particles, like, for example, the mass (inertia). We discuss in some detail several possible particular forms for the extra force, and the acceleration law of the particles is derived. Therefore, the constancy of the galactic rotation curves may be considered as an empirical evidence for the existence of the extra dimensions.
