Beyond the Equivalence Principle: Gravitational Magnetic Monopoles

TL;DR

This paper explores the theoretical concept of gravitational magnetic monopoles, proposing their properties, how they interact with gravity, and how they differ from ordinary matter within the framework of general relativity.

Contribution

It introduces the hypothesis of gravitational magnetic monopoles, defines their gravitational interactions, and discusses their motion in effective metrics, extending the analogy with electromagnetic monopoles.

Findings

H-poles violate the equivalence principle.

H-poles are accelerated by gravitational fields.

H-poles follow geodesics in an effective metric.

Abstract

We review the hypothesis of the existence of gravitational magnetic monopoles (H-pole for short) defined in analogy with the Dirac's hypothesis of magnetic monopoles in electrodynamics. These hypothetical dual particles violate the equivalence principle and are accelerated by a gravitational field. We propose an expression for the gravitational force exerted upon an H-pole. According to GR ordinary matter (which we call E-poles) follows geodesics in a background metric. The dual H-poles follows geodesics in an effective metric.
