Complete Unified Relaxation-Driven Cyclic Cosmology (RDCC): Full Synthesis of All Versions, Companions, and Extensions

Complete Unified Relaxation-Driven Cyclic Cosmology (RDCC): Full Synthesis of All Versions, Companions, and Extensions (Synthesis v1.0) This document is a complete, uncompressed synthesis of all knowledge from Relaxation-Driven Cyclic Cosmology (RDCC), incorporating every version from v1.0 to v16.0, all conceptual companions, structural extensions, and dualistic extensions. It preserves all details, mathematical descriptions, and iterative refinements to form a coherent, comprehensive overview. RDCC is presented as a minimalist, eternally cyclic framework based on standard Einstein gravity and a single complex scalar field Φ in a tilted double-well potential (emergent tilt from quantum corrections). It unifies cosmological phenomena through structural dualism in a globally CPT-symmetric, timeless spacetime, resolving tensions like Hubble/S8, evolving dark energy, and singularities without inflation or modified gravity. Key elements include:- Historical evolution of all versions and companions- Theoretical core (action, potential, CPT symmetry, bounce dynamics)- Mirror sector resolutions and thermodynamics- Perturbations, structure formation, and simulations- Gravitational waves and observational predictions- Quantum and dualistic extensions (speculative elements marked)- Entropy dynamics, EFT consistency, naturalness- Data confrontation and future outlook This synthesis serves as a master reference for RDCC, with the latest v16.0 integrated (precision two-sector dynamics, mirror refinements, GW forecasts).
