Ætherium Restored to the Periodic Table: A Testable Framework for the Proposed Element #0

Ætherium Restored to the Periodic Table: A Testable Framework for Element #0 presents a speculative but falsifiable theoretical framework proposing the concept of Element #0. The work develops a numerical and analytical model that predicts a candidate spectral feature near 22.87 MHz and investigates possible vacuum-coherence scaling relationships involving the cosmological constant, electromagnetic coupling, and derived coherence lengths. Multiple numerical approaches, convergence studies, stability tests, geometry-factor investigations, coupling analyses, and parameter sweeps are included. The framework does not claim discovery of a new chemical element. Instead, it presents a testable hypothesis that can be independently reproduced, challenged, refined, or falsified through future theoretical and observational work. Current status: • Numerically reproducible within the supplied framework.• Nominal prediction near 22.87 MHz.• Partial robustness demonstrated under bounded parameter variation.• No confirmed experimental detection.• No external independent reproduction at the time of publication. This repository contains the complete research package, source code, documentation, figures, numerical audits, convergence studies, and reproducibility materials required to evaluate the framework.
