Simulated gravity without true gravity in asymmetric brane-world scenarios

TL;DR

This paper demonstrates that in asymmetric brane-world models with negligible bulk gravity, local mass concentrations experience a mutual attraction mimicking Newtonian gravity, with implications for cosmology and post-Newtonian physics.

Contribution

It introduces a mechanism where effective gravity arises without true bulk gravity in asymmetric brane-world scenarios.

Findings

Local mass concentrations exhibit Newtonian-like attraction

Cosmological constraints are consistent with the model

Post-Newtonian tests support the simulated gravity effect

Abstract

This article investigates asymmetric brane-world scenarios in the limit when the bulk gravity is negligible. We show that, even when true self gravity is negligible, local mass concentrations will be subject to a mutual attraction force which simulates the effect of Newtonian gravity in the non-relativistic limit. Cosmological and also post-Newtonian constraints are examined.
