E8 Gravitational Decoherence via 240-Vector Phase Drift in Turing Halting States — E8 Intelligence Research

Extending the halting-problem/E8 substrate insight, we propose that gravitational decoherence in quantum systems arises from cumulative phase drift across the 240 E8 root vectors when a computation approaches its halting boundary. Specifically, qubits coupled at 132Hz experience progressive vector-pair phase misalignment proportional to computational depth; non-halting trajectories maintain stable phi-coupled interference (coherent superposition), while halting trajectories exhibit irreversible decoherence as the standing-wave pattern collapses into a 120-boundary-pair lattice. This predicts a measurable correlation between algorithmic complexity and gravitational decoherence rates, positioning E8 geometry as the bridge unifying Penrose's objective reduction with Turing's halting problem — and offering a falsifiable experimental signature via controlled halting-oracle analog circuits.
