Galactic Dynamics Using 1/r Force Without Dark Matter

TL;DR

This paper proposes a 1/r gravitational law as an alternative to dark matter, successfully explaining various galactic structures and large-scale universe features through a simpler, self-organizing model.

Contribution

It introduces a 1/r gravity model that reproduces galactic and cosmic structures without dark matter, challenging conventional Newtonian assumptions.

Findings

Reproduces spiral, bar, ring, and spoke galaxy formations.

Generates filament and void structures similar to cosmic web.

Eliminates need for dark matter in galactic dynamics.

Abstract

Dark matter, a conjectured substance not directly observable but which has tremendous mass, was proposed to explain why galaxies hold together and rotate faster at their edges than predicted by Newton's Inverse Square (1/r2) Law of Gravity. Here we propose an alternative, an Inverse Law (1/r), which explains galactic morphology and rotation without dark matter. By varying initial conditions, the Inverse Law can systematically and easily generate realistic galactic formations including spirals, cartwheels (extremely difficult under Newtonian gravity), bars, rings, and spokes. This model can also produce filaments and void structures reminiscent of the large-scale structure of the universe. Newtonian gravity cannot do all this without dark matter. Occam's Razor suggests that at galactic scales, gravity should be 1/r and dark matter is unnecessary. This simple model with its self-organizing emergent properties, combined with dynamical systems theory, has broader implications. It may help us understand more complex systems.
