AM Model Derives GR and QM as Emergent Effective Theories, Cosmological Constant Solution and Laboratory Predictions

We present a concise, constructive framework in which General Relativity (GR) and Quantum Mechanics (QM) arise as effective, low‑energy theories of a deeper Absolute Medium (AM). Starting with the AM Master Action constrained by the Medium Invariance Principle (MIP), we: (i) build an effective metric and geodesic motion for AM‑bound observers from elastic pressure and sink–vortex flow; (ii) derive a Schrödinger‑type envelope equation for coarse‑grained AM fluctuations with a Bohm‑like quantum‑potential term originating in AM pressure curvature; and (iii) outline scaling links connecting constants in the effective theories to AM microstructure parameters (L_fund, K_AM, ρ_AM, k, C_v). The result demonstrates “derivation, not replacement”: GR and QM emerge as sectors of a single substrate dynamics. Finally, the Absolute Medium (AM) Model offers a natural solution to the cosmological constant problem and produces unique laboratory predictions that distinguish it from GR and QM.
