DTQEM (Dual‑Time Quantum Entanglement Model) attributes non‑locality to a negative imaginary time carried by entangled particles. Calibrated to Gisin’s lower bound (v>1e7c at 0K) and returning to classical speed at 300K, it explains thermal decoherence, Heisenberg uncertainty, and double‑slit fringe contrast. Includes interactive Python simulation.
