Wormholes supported by a combination of normal and quintessential matter in Einstein and Einstein-Maxwell gravity

TL;DR

This paper demonstrates that traversable wormholes can be supported by a combination of normal and quintessential matter in Einstein-Maxwell gravity, with potential for safe travel and signal transmission.

Contribution

It introduces a novel combined matter model supporting traversable wormholes with zero tidal forces in Einstein-Maxwell gravity and explores conditions for eliminating electric fields in Einstein gravity.

Findings

Wormholes supported by combined matter can have zero tidal forces.

Electric fields can be eliminated in Einstein gravity, but with high tidal forces.

Such wormholes can transmit signals despite lacking electric fields.

Abstract

It is shown in the first part of this paper that a combined model comprising ordinary and quintessential matter can support a traversable wormhole in Einstein-Maxwell gravity. Since the solution allows zero tidal forces, the wormhole is suitable for a humanoid traveler. The second part of the paper shows that the electric field can be eliminated (Einstein gravity), but only by tolerating enormous tidal forces. Such a wormhole would still be capable of transmitting signals.
