COMPLETE RESEARCH RECORD — ZENODO DEPOSIT Author: Miguel Ángel Percudani ORCID: 0009-0007-1748-3212 ═══════════════════════════════════════════════════════════════ ABSTRACT ═══════════════════════════════════════════════════════════════ This work presents a first-principles resolution of the cosmological constant problem within the Unified Applicable Time (UAT) framework. The vacuum energy density is derived from three independent physical inputs, each constrained by distinct principles: PILLAR 1 — INFORMATIONAL: κ_crit = 10⁻⁷⁸ Explicit calculation from the Bekenstein bound on the particle horizon (R ≈ 46.5 Gly) yields N_accessible ≈ 10⁷⁸ accessible bits, giving κ_crit = 1/N_accessible = 10⁻⁷⁸. Uncertainty: ±0.5 in exponent. PILLAR 2 — GEOMETRIC-DIMENSIONAL: φ/2 = 0.809017 The complex 4×4 coherence matrix of the 8-phase causal array (k_early = 0.96734 from UAT Lagrangian) yields λ_max ∝ φ = 1.618034. Combined with LQG spectral dimension flow (d_S: 4 → 2): d_eff = d_S(UV) × φ / d_S(IR) = 2φ/4 = φ/2. PILLAR 3 — THERMODYNAMIC: 3/4 = 0.750000 Quadratic scaling of the double-well potential V ∝ δ² near its minimum yields equipartition at half-phase: 1 − (1/2)² = 3/4. (Heuristic derivation; full rigor under investigation.) These combine to give α = φ/2 + 3/4 = 1.559017, yielding: V₀ = E_Planck × κ_crit^α = 2.50 × 10⁻¹²² M_Pl⁴ ρ_Λ ≈ 6.90 × 10⁻²⁷ J/m³ Matching Planck 2018 (6.83 ± 0.08 × 10⁻²⁷ J/m³) with ~1% agreement. No parameters were fitted to the cosmological constant itself. ═══════════════════════════════════════════════════════════════ FALSIFIABLE PREDICTIONS ═══════════════════════════════════════════════════════════════ • Black hole entropy correction: S = A/(4ℓ²) − (φ/2)·ln(A/(4ℓ²)) • Hawking radiation suppression: P_UAT = (3/4) × P_Hawking • Golden Dirac comb in gravitational wave ringdown (LISA, 2035) • Testable with: LISA, CTA/LHAASO, Fermi-LAT/HAWC, Euclid/Roman ═══════════════════════════════════════════════════════════════ METHODOLOGICAL LESSONS (Documented in Section 5) ═══════════════════════════════════════════════════════════════ This investigation included an extensive exploratory phase whose results were discarded following rigorous statistical calibration: • LIGO/Virgo ringdown search: Null result after Monte Carlo PAR protocol (500 iterations). Signal indistinguishable from noise at ±1% tolerance. • Fibonacci ratio detection in 8 astronomical catalogs (Kepler, Chandra, Fermi, JWST, HST, LISA Pathfinder, Planck, DESI): All results invalidated after Monte Carlo test revealed true false-positive rate of 33.7% (not the assumed 5%). These methodological lessons are documented as contributions to best practices in astrophysical pattern detection. ═══════════════════════════════════════════════════════════════ CONTENTS ═══════════════════════════════════════════════════════════════ • Final_Report.pdf — Complete manuscript (15 pages, 2 figures, 2 tables) • Final_Report.tex — LaTeX source • deep_resolution_ccp.py — Analytical derivation script with: - 4×4 complex coherence matrix diagonalization - k_early derivation from Lagrangian constraints - N_accessible calculation from Bekenstein bound - Numerical verification of all constants ═══════════════════════════════════════════════════════════════ KEYWORDS ═══════════════════════════════════════════════════════════════ cosmological constant, dark energy, vacuum energy density, golden ratio, causal coherence, Bekenstein bound, Loop Quantum Gravity, spectral dimension, 8-phase coherence matrix, black hole thermodynamics, Hawking radiation, primordial black holes, gravitational waves, LISA, falsifiable predictions, look-elsewhere effect, Monte Carlo calibration, Unified Applicable Time, UAT framework ═══════════════════════════════════════════════════════════════ REFERENCES ═══════════════════════════════════════════════════════════════ UAT Framework: DOI: 10.5281/zenodo.17729221 UCP Constant: DOI: 10.5281/zenodo.17718670 ═══════════════════════════════════════════════════════════════ LICENSE ═══════════════════════════════════════════════════════════════ Creative Commons Attribution 4.0 International (CC BY 4.0)
