The Newtonian limit at intermediate energies

TL;DR

This paper investigates the Newtonian limit in Modified Gravity Models, revealing that at intermediate energies the limit is well-defined, with modifications to gravity occurring at low densities or curvatures, contrasting traditional low-energy views.

Contribution

It demonstrates that the Newtonian limit in certain MGMs is well-defined at intermediate energies, challenging the conventional low-energy perspective.

Findings

Newtonian limit is well-defined at intermediate energies in MGMs

Gravity is modified at low densities or curvatures

Contrasts with the usual low-energy interpretation of gravity

Abstract

We study the metric solutions for the gravitational equations in Modified Gravity Models (MGMs). In models with negative powers of the scalar curvature, we show that the Newtonian Limit (NL) is well defined as a limit at intermediate energies, in contrast with the usual low energy interpretation. Indeed, we show that the gravitational interaction is modified at low densities or low curvatures.
