Spiralicity and Motion on Cosmic Scale

TL;DR

This paper proposes a new cosmic model linking spiral galaxy trajectories and velocities, where dynamics depend on galaxy velocity rather than acceleration, involving dark matter with quadratic and non-linear drag forces.

Contribution

It introduces a novel scenario connecting spiral trajectories and velocities on cosmic scales, differing from MoND by focusing on velocity-dependent dynamics.

Findings

Galaxies exhibit spiral trajectories with specific velocity patterns.

Dark matter modeled as quadratic fluid resistance and non-linear radial drag.

The scenario explains observed asymptotic tangential velocities.

Abstract

We hypothesize a simple scenario to associate spiral-shaped trajectories and asymptotic tangential velocities according to observations found on deep space scales. As a difference with alternative Modified Newton Dynamics (MoND), in our scenario the dynamics at cosmic distances depends on the velocity of the rotating galaxy instead of its acceleration. We assume dark matter to exert a quadratic fluid resistance force with an added non-linear drag force in the radial direction.
