This project treats anti-gravity like a control problem: not "push up," but "decouple down." We model an example universe where gravity coupling has a phase-like knob that can be driven into cancel or repulse states through high-Q resonance and phase-lock. We refer to this model as the Eskridge Force hypothesis. The goal is not to claim real anti-gravity, but to build a systemic simulator and experimental framework that clarifies what would have to be true, what fails first, and what evidence could distinguish new coupling from ordinary electromagnetic artifacts.
This is a theoretical and simulation-driven research artifact. It does not provide instructions for building hazardous devices or making real-world propulsion claims. It focuses on modeling, measurement logic, and falsifiable predictions.
