Stability of cylindrical thin shell wormhole during evolution of universe from inflation to late time acceleration

TL;DR

This paper studies the stability and evolution of cylindrical wormholes throughout the universe's history, revealing two types with distinct roles in cosmic inflation and late-time acceleration, and their potential to cause universe destruction.

Contribution

It introduces two types of cylindrical wormholes linked to different cosmic epochs and analyzes their stability and impact on universe evolution.

Findings

First wormhole type facilitates inflation by transferring energy from extra dimensions.

Second wormhole type induces late-time acceleration and may lead to a big rip.

Wormhole parameters grow faster than the scale factor, causing universe destruction.

Abstract

In this paper, we consider the stability of cylindrical wormholes during evolution of universe from inflation to late time acceleration epochs. We show that there are two types of cylindrical wormholes. The first type is produced at the corresponding point where k black F-strings are transited to BIon configuration. This wormhole transfers energy from extra dimensions into our universe, causes inflation, loses it's energy and vanishes. The second type of cylindrical wormhole is created by a tachyonic potential and causes a new phase of acceleration. We show that wormhole parameters grow faster than the scale factor in this era, overtake it at ripping time and lead to the destruction of universe at big rip singularity.
