Recovering General Relativity from massive gravity

TL;DR

This paper demonstrates how massive gravity theories can recover the predictions of General Relativity in the weak-field limit through numerical solutions, confirming the Vainshtein mechanism's effectiveness.

Contribution

It provides the first explicit numerical solutions showing the recovery of Schwarzschild solutions in massive gravity via the Vainshtein mechanism.

Findings

Recovery of Schwarzschild solution in massive gravity

Numerical evidence supporting the Vainshtein mechanism

Confirmation of GR predictions in massive gravity context

Abstract

We obtain static, spherically symmetric, and asymptotically flat numerical solutions of massive gravity with a source. Those solutions show, for the first time explicitly, a recovery of the Schwarzschild solution of General Relativity via the so-called Vainshtein mechanism.
