Can Born Infeld Gravity Explain Galaxy Rotation Curves?

TL;DR

This paper examines whether Born-Infeld gravity can account for galaxy rotation curves and finds that the approximation used in the model fails at large distances, questioning its effectiveness.

Contribution

The study critically analyzes the Born-Infeld gravity model's applicability to galaxy rotation curves and identifies limitations in its current approximation.

Findings

Approximation breaks down at large distances

Born-Infeld gravity may not fully explain galaxy rotation curves

Challenges in modeling dark matter effects with this theory

Abstract

A Born-Infeld theory has been proposed in order to explain both dark matter and dark energy. We show that the approximation used to deduce the flat rotation curves in this model breaks down at large distances in a spherically symmetric configuration.
