Creating Cosmologically Unique Identifiers Using Cosmic Microwave Background Radiation

Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
The article explores the challenge of creating globally unique identifiers for objects in a cosmological context, particularly as humanity expands beyond Earth. It discusses the limitations of current ID systems (like UUIDs) that rely on time, location, or random generation, and proposes a solution using the cosmic microwave background radiation as a universal entropy source. The author explains how to create IDs that are guaranteed unique across space and time by incorporating cosmic coordinates and CMB measurements, enabling reliable identification for interstellar devices, satellites, and future space infrastructure.
Key quotes
· 5 pulledWe are an exploratory species, just past the solar system now, but perhaps one day we will look back and call our galaxy merely the first.
How do we assign IDs to devices (or any object) so the IDs are guaranteed to always be unique?
Being able to identify objects is a fundamental tool for building other protocols, and it also underpins manufacturing, logistics, communications, and security.
Every ship and satellite needs an ID for traffic control and maintenance history.
The cosmic microwave background radiation provides a universal entropy source that can be measured from any location in the observable universe.
