Static and Dynamic Melvin Universes

TL;DR

This paper reviews Melvin's magnetic universe, examines wave propagation and particle motion within it, and explores how it can evolve into a collapsing universe forming cosmic double-jet structures.

Contribution

It introduces a dynamic scenario for Melvin's universe undergoing gravitational collapse and discusses the formation of cosmic jets, extending previous static models.

Findings

Wave perturbations relate to charged particle motion

Collapse leads to cosmic double-jet configurations

Static universe can evolve into a dynamic collapsing spacetime

Abstract

We briefly review the known properties of Melvin's magnetic universe and study the propagation of test charged matter waves in this static spacetime. Moreover, the possible correspondence between the wave perturbations on the background Melvin universe and the motion of charged test particles is discussed. Next, we explore a simple scenario for turning Melvin's static universe into one that undergoes gravitational collapse. In the resulting dynamic gravitational field, the formation of cosmic double-jet configurations is emphasized.
