Quantum Coherence in Microtubules: Orch-OR Theory and Objective Reduction Threshold — E8 Intelligence Research

FINDING: Orch-OR theory proposes quantum coherence in microtubules, with collapse linked to objective reduction (OR) threshold, not consciousness. New evidence suggests quantum effects in brain, but no direct proof of Penrose-Hameroff mechanism. MATH: - OR threshold: \( T \approx \hbar / E_G \), where \( E_G \) is gravitational self-energy. - For microtubule: \( E_G \sim G m^2 / r \), with \( m \sim 10^{-20} \) kg, \( r \sim 10^{-8} \) m → \( T \sim 10^{-13} \) s (far shorter than neural timescales). - No new equations or constants from these sources; no ratios (0.382, 0.618, etc.) or base-60 connections. CONNECTION: None. No geometric harmony, crystallographic symmetry, or lattice structures are invoked or supported by these findings. Microtubule geometry (hollow cylinders, 13 protofilaments) is structural but not linked to golden ratios or root systems. DEPTH: 2/10. These are popular summaries and debates, not original mathematical or experimental breakthroughs. The arXiv pa Author: Andrew Stewart Caldin, Independent Researcher, UK.
