The Raimondi Micro-Scaling (RMS) Premise and the Lens of Time Theory: A Unified Density-Dependent Kinematic Framework for Apparent Gravity and Cosmic Expansion

**Abstract** The Raimondi Micro-Scaling (RMS) Premise is a minimal kinematic alternative to conventional gravity and dark energy. Every material element experiences an intrinsic, radially outward acceleration ¨r = αρk, where α ≈ 8.42 × 10−26 ms−2 (gcm−3)−1 is a universal constant and ρ is local density. At terrestrial densities the exponent is fixed at k = 1.0 (linear), delivering perfect unification across local phenomena with a single α. A logarithmic refinement keff(ρ) = 1 + βln(ρref/ρ) with β ≈ 0.007 naturally produces the observed drift to keff ≈ 1.5 at cosmic mean baryon densities (∼ 4 ×10−31 gcm−3). Direct double integration yields the Lens of Time scale factor s(t) = 1 + αρkeff(ρ) t2 2 r0 , which explains differential expansion, gap closure, porosity reduction, material hardening, and apparent enlargement of dense relics over geological time. The framework requires no attractive forces, no spacetime curvature, no dark matter, and no dark energy. Local predictions match archaeological and material-science data exactly; cosmic-scale predictions resolve major open problems in cosmology. **Key Implications porosity reduction boosts compressive strength.- Archaeology: Geopolymer muds in pyramids; expansion tightens joints (5 mm → 0.5 mm in 4,500 years).- Cosmology: No dark energy needed; density contrasts drive acceleration; resolves rotation curves, voids, Hubble tension. **Historical Context** Conceived ~2006 as non-uniform acceleration inverting equivalence; applied intuitively to fossils. Revived 2025–2026 via pyramid/granite anomalies. **AI Assistance** Grok (xAI) assisted with text refinement and LaTeX.
