A Deductive Approach to Observer-Centric Cosmology

Why Each Observer Can Be Viewed as the Center of the Multiverse

Abstract

This article presents an observer-centric viewpoint of the multiverse, arguing that each observer can be considered its “center” and that the reality surrounding the observer emerges as an optical projection from that vantage point. Drawing from principles in relativity, quantum theory, and philosophical arguments on perception, I propose a structured, deductive framework illustrating how and why every observer might validly regard themselves as central to their observable cosmos.

1. Introduction

In standard cosmology, there is no absolute center to the universe: the cosmological principle holds that the universe is homogeneous and isotropic on large scales. Yet, from each observer’s vantage point, it remains equally valid to claim, “I am at the center of my observable domain.” This paradox — no absolute center globally, yet each observer has a valid claim locally — has profound implications for our understanding of cosmic structure, time, and the nature of reality. In this article, we formalize a deductive proof for an observer-centric perspective, extending it to a multiverse framework in which the world around us can be viewed as an optical projection…
