Relaxation-Driven Cyclic Cosmology (RDCC) v1.17 A Minimal Eternal Model with Emergent Tilt, CPT-Conjugate Mirror Sector, Natural Resolution of the Hubble Tension, and Predicted Stochastic GW Background

Relaxation-Driven Cyclic Cosmology (RDCC) v1.17 A minimalist eternal cyclic cosmological model based on a single complex scalar field in a tilted double-well potential with emergent tilt from Coleman-Weinberg corrections. New in v1.17 (December 25, 2025): - Quantitative derivation of the stochastic gravitational-wave background (SGWB) generated at the nonsingular bounce. - Characteristic peaked spectrum Ω_GW(f) with f_peak ∼ 10^{-3}–10^{-2} Hz and amplitude in the range ∼10^{-15}–10^{-13}, placing the signal within LISA's sensitivity window and potentially detectable with significant signal-to-noise ratio. - Comparison plot of the predicted SGWB with approximate LISA sensitivity curve. - Minor refinements: Ontological implications moved to Discussion as interpretational perspective; cautious phrasing of detectability. RDCC remains strictly minimalist: one field, standard gravity, no new particles, no modified gravity, no inflation required. Primary testable predictions: Enhanced late-time ISW (~12% low-ℓ excess), stochastic GW background (LISA), 21-cm modulations (SKA), mild small-scale suppression, mild evolving dark energy resolving Hubble tension.
