Creation and Structure of Baby Universes in Monopole Collisions

TL;DR

This paper explores how magnetic monopole collisions can trigger topological inflation, potentially creating baby universes and leading to an eternally reproducing multiverse scenario.

Contribution

It provides a detailed analysis of the global spacetime structure resulting from monopole collisions and introduces the concept of topological inflation within monopoles as a mechanism for universe reproduction.

Findings

Monopole collisions can induce topological inflation.

Topological inflation within monopoles can produce baby universes.

The resulting spacetime may contain a timelike singularity or avoid it.

Abstract

Under certain circumstances, the collision of magnetic monopoles, topologically locked-in regions of false vacuum, leads to topological inflation and the creation of baby universes. The future evolution of initial data represented by the two incoming monopoles may contain a timelike singularity but this need not be the case. We discuss the global structure of the spacetime associated with monopole collisions and also that of topological inflation. We suggest that topological inflation within magnetic monopoles leads to an eternally reproducing universe.
