Particle motion around a static axially symmetric wormhole

TL;DR

This paper investigates how the motion of particles and photons around a static axially symmetric wormhole differs from that near black holes, proposing a method to distinguish these objects through precise measurements.

Contribution

It introduces an analysis of test particle and photon trajectories in a wormhole spacetime to identify observable differences from black hole environments.

Findings

Particle and photon motions differ between wormholes and black holes.

Simultaneous measurements can potentially distinguish wormholes from black holes.

Provides a theoretical basis for observational tests of wormhole existence.

Abstract

We consider the properties of a static axially symmetric wormhole described by an exact solution of Einstein's field equations and investigate how we can distinguish such a hypothetical object from a black hole. To this aim, we explore the motion of test particles and photons in the wormhole's space-time and compare it with the particle dynamics in the well known space-times of Schwarzschild and Kerr black holes. We show that precise simultaneous measurement of test particle motion and photon motion may provide the means to distinguish the wormhole geometry from that of a black hole.
