More about wormholes in generalized Galileon theories

TL;DR

This paper investigates generalized Galileon theories in higher-dimensional spacetimes and demonstrates that such theories cannot support stable, static, spherically symmetric, asymptotically flat, traversable wormholes.

Contribution

It provides a no-go result showing the incompatibility of stable wormholes with a broad class of generalized Galileon theories in higher dimensions.

Findings

Stable, static, spherically symmetric wormholes are not supported in these theories.

Theories do not admit asymptotically flat, traversable wormhole solutions.

Results extend previous no-go theorems to higher-dimensional Galileon models.

Abstract

We consider a class of generalized Galileon theories within General Relativity in space-times of more than two spatial dimensions. We show that these theories do not admit stable, static, spherically symmetric, asymptotically flat and traversable Lorentzian wormholes.
