What is the present-day status of The Copernican Principle?

TL;DR

This paper discusses the implications of the Copernican principle, suggesting that our universe may not be unique and proposing a theoretical framework involving gravitational instantons to explain possible transitions to other universes.

Contribution

It introduces a novel perspective on the Copernican principle by linking it to gravitational instantons and universe tunneling concepts.

Findings

Proposes a mechanism for universe transition via gravitational instantons.

Highlights the non-uniqueness of our universe according to the Copernican principle.

Connects cosmological principles with quantum tunneling theories.

Abstract

I point out that according to the Copernican principle our universe is not unique. The way to make sense out of this statement is for us to construct a gravitational instanton that will tunnel out of our vacuum into another, to form a universe other than our Hubble bubble.
