On the Possibility of the Existence of Wormholes in Nature

TL;DR

This paper explores the theoretical possibility of traversable wormholes in nature by analyzing new exact solutions to Einstein's equations with electromagnetic and dilaton fields, suggesting they could be observable as black hole mimics.

Contribution

It introduces new rotating wormhole solutions with magnetic and electric fields, satisfying energy conditions, and discusses their potential observability and relation to string theory.

Findings

Wormholes can be traversable near the poles with manageable tidal forces.

The solutions satisfy energy conditions for dilaton-like fields.

Wormholes may appear as black hole mimics in nature.

Abstract

To date, many exotic predictions of Einstein's equations have been corroborated, with one exception: wormholes (WHs). In this work, we analyse a new exact solution combination to the Einstein-Maxwell-Dilaton or Phantom equations, which represent rotating WHs with magnetic and electric fields. The solution contains a ring singularity that, like other solutions, satisfies Wormhole Cosmic Censorship; that is, the singularity is causally disconnected by the WH throat. We show that this WH is traversable through regions close to the poles, where the tidal forces and magnetic field are reasonably small. We satisfy the energy conditions for the dilaton-like solution. We argue that if dilaton-like interactions can exist in nature, for example, if extra dimensions exist as in superstring theory, WHs are a natural realistic prediction of Einstein's equations, and we should be able to observe them somehow, probably as black hole mimics.We present several examples of realistic WH that may occur in nature, and we also introduce a new exact black hole solution.
