Late-Universe Predictions & Experimental Roadmap

Abstract

Synthesises CMB, BAO and growth-rate tests for RFT; refines scalaron dark-energy evolution (w₀ ≈ –0.995, wₐ ≈ +0.05) and lays out a 2025-2050 observational roadmap—LIGO-O5 echoes, Euclid lensing, CMB-S4 B-modes—to confirm or falsify the theory.

Key Results

• Matches Planck CMB (nₛ≈0.965, r≈0.004) and DESI BAO at <1 %
• Predicts GW echo delays ≈ 0.1 s at 1 % amplitude for 30 M⊙ BH mergers
• {'Dark-energy thawing': 'w₀, wₐ values testable by Euclid + LSST'}
