description: Patent Notice — “Tick of Time” Formula and Causal-Density Framework

This record accompanies the author’s ongoing Unified Causal-Density research program and formalizes the geometric clock-rate constraint expressed by the “tick of time” relation

dτdt=e−αcausal r,αcausal≈(0.8–1.0)×10−26 m−1.\frac{d\tau}{dt} = e^{-\alpha_{\text{causal}}\,r}, \quad \alpha_{\text{causal}} \approx (0.8–1.0)\times10^{-26}\ \text{m}^{-1}.dtdτ=e−αcausalr,αcausal≈(0.8–1.0)×10−26 m−1.

The underlying causal-density method, including its physical interpretation and computational implementation, is protected under U.S. Provisional Patent Application No. 63/896,100, filed 2025 (Jacob Barnes, sole inventor).
