Wormholes in Bulk Viscous Cosmology

TL;DR

This paper studies how the accretion of viscous phantom energy influences the growth of wormholes, revealing that higher bulk viscosity accelerates wormhole mass increase.

Contribution

It introduces the effect of bulk viscosity in phantom energy accretion onto wormholes, a novel aspect not extensively explored before.

Findings

Large bulk viscosity leads to rapid wormhole mass increase.

Small or zero bulk viscosity results in slower mass growth.

Bulk viscosity significantly impacts wormhole evolution.

Abstract

We investigate the effects of the accretion of phantom energy with non-zero bulk viscosity onto a Morris-Thorne wormhole. We have found that if the bulk viscosity is large then the mass of wormhole increases rapidly as compared to small or zero bulk viscosity.
