Draft:Cosmodex Unit

The Cosmodex Unit (CDU) is a proposed astronomical unit of distance with a value of 10^(10^115) meters. This unit is conceived as a tool for conceptualizing and discussing extremely vast distances encountered within theoretical models of an infinite universe.

Origin and Rationale
The Cosmodex Unit originates from inspiration by physicist Max Tegmark's calculations concerning distances at which an identical Hubble volume (a region of the observable universe surrounding an observer) might be found in an infinite universe model [1][2]. While speculative, this proposed unit facilitates expressing cosmic scales exceeding those typically used in astronomy.

Development
The concept of the Cosmodex Unit, and the term itself, were formalized and publicly introduced in 2024 by Jeffrey Michael Schatz in collaboration with a large language model (LLM) assistant through online discussion [3]. Its primary aim serves as a reference point for thought experiments within infinite universe and multiverse frameworks.

Applications
Facilitates communication and calculation when grappling with the potentially incomprehensible scale of infinity in cosmological contexts. Provides a vocabulary term when contemplating patterns or the possibility of repeated cosmic structures across immeasurable distances.
