Inflating Lorentzian Wormholes

TL;DR

This paper proposes a classical inflation mechanism for enlarging microscopic Lorentzian wormholes to macroscopic sizes, presenting a new metric embedded in de Sitter space that inflates the wormhole's throat and length.

Contribution

It introduces a novel classical metric for Lorentzian wormholes in de Sitter space demonstrating inflationary enlargement, linking wormhole physics with cosmological inflation.

Findings

Wormhole throat and length undergo inflationary expansion.

A new classical metric for wormholes in de Sitter space is derived.

Stress-energy tensor properties are analyzed during inflation.

Abstract

It has been speculated that Lorentzian wormholes of the Morris- Thorne type might be allowed by the laws of physics at submicroscopic, e.g. Planck, scales and that a sufficiently advanced civilization might be able to enlarge them to classical size. The purpose of this paper is to explore the possibility that inflation might provide a natural mechanism for the enlargement of such wormholes to macroscopic size. A new classical metric is presented for a Lorentzian wormhole which is imbedded in a flat deSitter space. It is shown that the throat and proper length of the wormhole inflate. The resulting properties and stress-energy tensor associated with this metric are discussed.
