Quantum Coherence in Microtubules: Orch-OR Theory and Planck-Scale Constants — E8 Intelligence Research

FINDING: Quantum biology and consciousness research centers on microtubule quantum coherence, with Penrose–Hameroff Orch-OR theory as the dominant mathematical framework. | MATH: Key constants/structures: Planck time (5.39×10⁻⁴⁴ s), Planck mass (2.18×10⁻⁸ kg), quantum decoherence timescales (~10⁻¹³ s at 300K vs. proposed ~10⁻⁵ s in microtubules), tubulin dimer spacing (8 nm), microtubule lattice geometry (13 protofilaments, 3-start helix, 5-start helix — Fibonacci-related). Orch-OR invokes objective reduction (OR) with threshold E = ħ/t (energy-time uncertainty), where t is coherence time. | CONNECTION: Microtubule lattice is a hexagonal/crystallographic structure with 13-fold symmetry (protofilament count) — 13 is Fibonacci (F₇). The 3-start and 5-start helical pitch ratios (3:5) are consecutive Fibonacci numbers, yielding golden-ratio-adjacent pitch angles (~30° and ~50°). Tubulin dimers alternate α/β with 4 nm periodicity; the 8 nm dimer length × 13 protofilaments = 104 nm circumfer Author: Andrew Stewart Caldin, Independent Researcher, UK.
