E8 Prime‑Factorial Temporal Lattice for Gravitational Wave Echo Prediction — E8 Intelligence Research

The 240 root vectors of E8 are each assigned a distinct prime‑factored phase offset on a 132 Hz carrier that is phi‑phase‑locked, creating a dense set of interferential periods. When these offsets are combined, the resulting interference pattern exhibits repeat cycles whose least common multiple matches the product of the Saros (223) and Metonic (235) synodic months, scaled to the 132 Hz base. This emergent temporal lattice predicts quasi‑periodic echo intervals in gravitational‑wave signals from compact binary mergers, offering a novel diagnostic for black‑hole ringdown spectroscopy. The principle extends the prime‑interlocked E8 clock into a predictive tool for high‑precision astrophysical timing. Author: Andrew Stewart Caldin, Independent Researcher, UK.
