Can the Interaction between Baby Universes Generate a Big Universe?

TL;DR

This paper investigates a toy model of interacting universes, demonstrating that a small baby universe can grow large through a third quantization process, offering insights into universe formation.

Contribution

It introduces a simple toy model showing how third quantization can enable small universes to become large, a novel approach in multiverse theories.

Findings

Small baby universes can grow large via third quantization.

Interaction mechanisms influence universe size evolution.

The model provides a new perspective on universe formation processes.

Abstract

We explore a simple toy model of interacting universes to establish that a small baby universe could become large ($\gg$ Planck length) if a third quantization mechanism is taken into account.
