From dark matter to MOND

TL;DR

This paper argues that MOND effectively explains galaxy dynamics and photometry, challenging the dark matter paradigm by providing a successful alternative algorithm for force distribution based on baryonic matter.

Contribution

It presents evidence supporting MOND as a viable alternative to dark matter, highlighting its success in explaining galaxy-scale phenomena.

Findings

MOND accurately predicts galaxy rotation curves

MOND explains systematic galaxy photometry and kinematics

Evidence challenges the necessity of dark matter on galactic scales

Abstract

MOND-- modified Newtonian dynamics-- may be viewed as an algorithm for calculating the distribution of force in an astronomical object from the observed distribution of baryonic matter. The fact that it works for galaxies is quite problematic for Cold Dark Matter. Moreover, MOND explains or subsumes systematic aspects of galaxy photometry and kinematics-- aspects that CDM does not address or gets wrong. I will present evidence here in support of these assertions and claim that this is effectively a falsification of dark matter that is dynamically important on the scale of galaxies.
