Relaxation-Driven Cyclic Cosmology (RDCC) v14.0: Unified Quantum Gravity, Full-Cycle Simulation, and Multi-Messenger Precision Cosmology

Relaxation-Driven Cyclic Cosmology (RDCC) v14.0: Unified Quantum Gravity, Full-Cycle Simulation, and Multi-Messenger Precision Cosmology This v14.0 release advances RDCC as a nonsingular, eternally cyclic cosmological framework based on a single effective complex scalar field Φ in a tilted double-well potential (tilt from radiative Coleman–Weinberg corrections). Field relaxation drives dynamic dark energy (w_DE > -1) and eternal breathing cycles. A gravitationally coupled CPT-conjugate mirror sector provides cold dark matter and resolves baryon asymmetry (η_B ≈ 6.1×10⁻¹⁰, Ω_DM/Ω_b ≈ 5.38), preserving global CPT symmetry exactly. Previous releases (v10.0–v13.0) established RDCC as a quantum-geometrically motivated, data-confronted alternative to ΛCDM, with bounce dynamics, primordial perturbations, RDCC–CLASS integration, structure formation, 21-cm reionization, and stochastic GW signatures. This v14.0 release advances RDCC along three axes:(i) a first quantum-gravity formulation of the bounce (RDCC Quantum Gravity v1.0): path-integral bounce formulation, Wheeler–DeWitt equation, quantum constraint algebra, bounce as tunneling amplitude, emergent time from entanglement flow, comparisons to LQC, CDT, AS, and GFT, with central prediction of bounce-GW and BH-echo correlations for multi-messenger signatures (LISA/ground-based detectors);(ii) full-cycle simulations over many cosmological cycles (Full-Cycle Simulation v1.0): multi-cycle evolution of entropy, curvature, anisotropies, mirror thermodynamics, baryon asymmetry, and dark-sector energy, with cycle-to-cycle drift, attractor behavior, and GPU-accelerated bounce-tracking;(iii) multi-messenger precision forecasts for the 2030–2035 era (Multi-Messenger Forecasts v1.0): forecasts for LISA bounce-GW/echoes, SKA Full-Array 21-cm, JWST DR3 high-z galaxies, PTA stochastic background, Euclid DR3 S_8/BAO, and CMB-S4 ΔN_eff, with Bayes-evidence log(B_RDCC/B_ΛCDM) ∼2–5 for simulated 2035 data. Additional modules refine RDCC–CLASS v3.0 (sub-percent precision for r_s, D(z), fσ_8, P(k)), structure formation v5.0 (hydrodynamical calibration against IllustrisTNG/EAGLE/FIRE, high-z galaxy counts), 21-cm & GW atlases v5.0 (bubble morphology, cross-correlations, echo-population statistics), parameter space v6.0 (6D posteriors, degeneracy maps), and observational pipeline v5.0 (joint likelihoods, nested sampling, tension-mapping between RDCC and ΛCDM). These upgrades position RDCC as a unified, quantengeometrically consistent, and fully testable cosmological paradigm. Falsifiability:- Instability or entropy blow-up over many simulated cycles- No alleviation of H_0/S_8 tensions in joint fits- Absence of predicted 21-cm flattening or delayed reionization (SKA/HERA)- No bounce-GW/echo signatures (LISA/PTA)- ΔN_eff > 0.1 inconsistent with mirror thermodynamics This version builds on: Relaxation-Driven Cyclic Cosmology (RDCC) v1.0: A Minimal Eternal Framework and Its Dynamical Realization: https://zenodo.org/records/18281686 Relaxation-Driven Cyclic Cosmology (RDCC) v2.0: A Minimal Eternal Framework with Dynamical Realization and Extensions: https://zenodo.org/records/18304744 Relaxation-Driven Cyclic Cosmology (RDCC) v5.0: Bounce-Matching Formalism, Mirror-Sector Dynamics, and Refined Gravitational Waves: https://zenodo.org/records/18307836 Relaxation-Driven Cyclic Cosmology (RDCC) v6.0: Black Hole Bounces as Local CPT-Fixpoints, Full Perturbation Transfer Matrix and Mirror-Sector Microphysics: https://zenodo.org/records/18312656 Relaxation-Driven Cyclic Cosmology (RDCC) v7.0: Quantum-Corrected Black Hole Bounces, Full Perturbation Transfer Matrix with Phase-Shift, and Mirror Microphysics https://zenodo.org/records/18327084 Relaxation-Driven Cyclic Cosmology (RDCC) v8.0: Parameter Space Exploration, Data Confrontation, and Predictive Structure Formation https://zenodo.org/records/18334398 Relaxation-Driven Cyclic Cosmology (RDCC) v9.0: Predictive Cosmology, Nonlinear Structure Formation, and Astrophysical Signatures https://zenodo.org/records/18336237 Relaxation-Driven Cyclic Cosmology (RDCC) v10.0: Unified Cosmology, Full Simulations, and Observational Pipelines https://zenodo.org/records/18336865 Relaxation-Driven Cyclic Cosmology (RDCC) v11.0: Entropy Dynamics, Mirror Thermodynamics, EFT Consistency, and Naturalness https://zenodo.org/records/18341147 Relaxation-Driven Cyclic Cosmology (RDCC) v12.0: Precision Predictions, Multi-Probe Confrontation, and Quantum-Geometric Completion https://zenodo.org/records/18346555 Relaxation-Driven Cyclic Cosmology (RDCC) v13.0: Quantum Completion, Global Consistency, and Predictive Cosmology https://zenodo.org/records/18348450 While the core of RDCC remains a structural, timeless framework with fixpoint character, this document explores a dynamical realization of the bounce mechanism to enable concrete, falsifiable predictions.
