Newtonian mechanics & gravity fully model disk galaxy rotation curves without dark matter

TL;DR

This paper demonstrates that Newtonian mechanics and gravity alone can fully explain the rotation curves of disk galaxies without invoking dark matter, based on re-examining the mass-rotation relationship.

Contribution

It presents a re-examination of galaxy rotation curves using only Newtonian physics, challenging the need for dark matter in explaining galactic dynamics.

Findings

Galactic rotation curves can be modeled without dark matter.

Archival gamma-ray data reveals structures correlating with stellar distributions.

Newtonian dynamics suffice to explain observed galaxy rotation behaviors.

Abstract

EGRET gamma-ray archival data used with GALPROP software show two ringlike structures in Milky Way Plane which roughly tally with distribution of stars ([1] & references therein). To understand fully the implications of this and similar results on detailed structure and rotation curve of especially Milky Way Disk as well as rotation curves of other galaxies as derived from spatially resolved spectroscopic data-cubes, a re-examination of the basis of the connection between mass density and rotation curve is warranted. Kenneth F. Nicholson's approach [2], which uses only Newtonian dynamics & gravity, is presented.
