Some examples of Hayward wormholes

TL;DR

This paper explores theoretical models of traversable wormholes linked to black holes, proposing possible transitions and methods for their construction based on existing black hole-wormhole interconvertibility theories.

Contribution

It introduces a new model for constructing traversable wormholes from black holes, incorporating the concept of interconvertibility and exotic matter.

Findings

Possible black hole to wormhole transitions identified

A toy model demonstrates transition mechanisms

Conversion to wormholes via exotic matter is feasible

Abstract

The first part of this paper discusses a model for the theoretical construction of a simple traversable wormhole with zero density that depends on a preexisting black hole. By assuming the interconvertibilty of black holes and wormholes proposed by S.A. Hayward, it is shown that a toy model suggested by the first model may yield several possible transitions from the preexisting black hole to a wormhole. A final topic is the conversion to a wormhole by assuming a specific model for the exotic matter.
