Wormholes supported by pure ghost radiation

TL;DR

This paper presents static, spherically symmetric wormhole solutions supported solely by negative energy density ghost radiation, which collapse into black holes when the radiation ceases.

Contribution

It introduces a new class of wormhole solutions sustained by pure ghost radiation, expanding understanding of exotic matter in general relativity.

Findings

Wormholes are supported by negative energy density ghost radiation.

Turning off the radiation causes collapse into Schwarzschild black holes.

The solutions are static and spherically symmetric.

Abstract

Traversible wormhole space-times are found as static, spherically symmetric solutions to the Einstein equations with ingoing and outgoing pure ghost radiation, i.e. pure radiation with negative energy density. Switching off the radiation causes the wormhole to collapse to a Schwarzschild black hole.
