Perihelion precession and deflection of light in gravitational field of wormholes

TL;DR

This paper calculates the perihelion precession and light deflection caused by wormholes, comparing these effects to black holes, and finds significant differences that could help distinguish between these exotic objects.

Contribution

It provides the first detailed comparison of gravitational effects like perihelion precession and light deflection between wormholes and black holes.

Findings

Differences in precession and deflection can reach tens of percent.

Wormholes produce measurable deviations from black hole predictions.

Results suggest potential observational signatures to identify wormholes.

Abstract

Quite exotic relativistic objects known as wormholes are hypothetical candidates for central machine of active galactic nuclei as well as black holes. We find the magnitude of the perihelion precession and the deflection of light in gravitational field of a wormhole and compare them with those for a black hole. The impact parameter is taken to be much larger than the wormhole throat size. We show that the relative difference between results for a black hole and a wormhole may be significant and amount to tens of percent.
