The Cosmological Cycle in Aetherium

This paper is part of the Aetherium Conceptualization Phase, which develops the early ontology, coherence framework, and foundational intuitions of the Aetherium substrate. The Cosmological Cycle in Aetherium develops a coherence‑first cosmological model in which the universe evolves through a sequence of global coherence modulation pulses in the Aetherium substrate. These pulses naturally generate the observed expansion history — including early‑time modulation, mid‑cycle ΛCDM‑like stability, and late‑time acceleration — without invoking a "big bang", dark energy, tuned potentials, or exotic fields. The framework replaces parameter‑driven cosmology with a single physical mechanism grounded in the substrate’s resonance‑compatibility architecture. The model yields clear observational signatures across CMB anomalies, PTA‑scale correlations, deviations in , and coherence‑pattern imprints in large‑scale structure. This paper establishes the conceptual foundation for a coherence‑driven cosmology and outlines a falsifiable, observationally anchored alternative to ΛCDM. Future work will develop the gravitational sector, derive the effective metric, and analyze structure formation in detail.
