Comments on the Cooperstock-Tieu Galaxy Model

TL;DR

This paper critiques the Cooperstock-Tieu galaxy model, demonstrating its internal inconsistency and showing that correcting it negates the model's ability to explain flat galaxy rotation curves without dark matter.

Contribution

It provides a critical analysis revealing the model's internal inconsistency and shows that fixing it removes its explanatory power for flat rotation curves.

Findings

The model is internally inconsistent.

Correcting the inconsistency eliminates its ability to explain flat rotation curves.

The model cannot be considered valid as originally proposed.

Abstract

The recently proposed Cooperstock-Tieu galaxy model claims to explain the flat rotation curves without dark matter. The purpose of this note is to show that this model is internally inconsistent and thus cannot be considered a valid solution. Moreover, by making the solution consistent the ability to explain the flat rotation curves is lost.
