Update: Multi-field Simulation Results 🧪

We simulated the coupled φ (Hole) and χ (environment) fields for 5 systems:

🔴 DF2 (high tidal field): ξ_eff ≈ 0.05 → Newtonian ✅🔵 Fornax (moderate tidal): ξ_eff ≈ 0.15 → extra gravity ✅🟢 Draco (isolated): ξ_eff ≈ 0.28 → strong extra gravity ✅🟣 Large disks: ξ_eff ≈ 0.30 → flat rotation curves ✅🟠 Solar System: screened by high density → no 5th force ✅

The key: χ (screening field) is sensitive to tidal environment.High tidal amplitude → φ and χ desynchronize → gravity becomes Newtonian.

This explains why DF2 is “dark matter free” while similar-density UDGs show extra gravity.
