Precision Cosmology Forecasts for Scalaron–Twistor RFT

Abstract

Maps the next-decade CMB and large-scale-structure measurements to concrete RFT predictions—Starobinsky-like n_s, r≈0.005, low-ℓ power suppression from a pre-inflationary bounce—and quantifies how experiments such as LiteBIRD and CMB-S4 can confirm or rule them at >5σ.

Key Results

• Predicts n_s = 0.960–0.967; CMB-S4 can halve current error bars
• Forecasts r ≈ 0.005, detectable by LiteBIRD/CMB-S4 at >5σ
• Bounce scenario explains low-ℓ TT, EE deficits and parity anomalies
