Cosmic Structure Formation from Chi-Memory in the Lattice Field Medium

This paper demonstrates that cosmic structure formation emerges naturally from the Lattice Field Medium (LFM) framework through the χ-memory mechanism. Using a 64³ lattice simulation governed by LFM's governing equations, we show that primordial density perturbations amplify via positive feedback: regions with elevated energy density develop χ-wells (reduced χ), which trap more energy, further deepening the wells. Key results:• Structure growth factor: 11.25ו Growth exponent: t^0.74 (ΛCDM predicts t^0.67) — within 10%• χ-E² correlation: r = 1.00 (perfect)• χ-well depth: Δχ = 2.58 The χ-memory mechanism explains dark matter phenomenology without particles: it is the substrate's memory of where matter was, creating persistent gravitational wells.
