L.C.Garcia de Andrade
TL;DR
This paper explores the weak gravitational field of a global monopole within Einstein-Cartan gravity, revealing that torsion induces a repulsive gravitational force, which differs from predictions in standard General Relativity.
Contribution
It introduces a novel solution for the gravitational field of a global monopole considering Cartan torsion as a Newtonian potential, highlighting torsion's repulsive effects.
Findings
Torsion causes a repulsive gravitational force.
The solution models the monopole's weak field in Einstein-Cartan theory.
Torsion's role differs from standard gravity predictions.
Abstract
The gravitational weak field of a global monopole in the Einstein-Cartan theory of gravity is investigated.To obtain this solution we assume that Cartan torsion takes the form of the Newtonian gravitational potential.From the geodesics it is possible to show that the torsionic monopole produces a repulsive gravitational force.
