Engineering Spacetime Curvature via Controlled Quantum Entanglement: A Testable Phenomenological Framework Grounded in Experiment – Version 9.0 (with Technical Proposal)

Version 9 (June 29, 2026) is a major structural and readiness upgrade to the framework.

Building on the quantitative foundation of Version 8, this revision adds: 
• Full explicit attribution paragraph to Bobrick & Martire (2021) with detailed originality statement (page 2).
• Explicit weak-field isotropic metric ansatz with Poisson equation and controlled-time matching (Section 3).
• Cleaned Figure 1 caption with proper Bobrick reference note.
• Complete Appendix B with the full algebraic 50/50 temporal-spatial light-deflection derivation and probe test prediction.
• Full technical proposal (6 pages) integrated as supplementary material, including detailed protocol, budget, timeline, and grant-ready text.
• All original content preserved verbatim with expanded clarity sections, restored length, and no material removed.

These additions make the work submission-ready, outreach-ready, and grant-ready while preserving the deliberately conservative spirit of the framework. The paper is now significantly more concrete, experimentally actionable, and positioned for immediate collaboration and funding applications. The framework remains fully consistent with Newtonian gravity, General Relativity in the classical limit, and positive-energy conditions.

Abstract
The ultimate goal of this research is faster-than-light (FTL) travel that would enable humanity to spread across the galaxy. The entanglement-modulated approach to curvature engineering provides a scientifically grounded stepping-stone toward that goal. This proposal presents a detailed, executable plan for Phase 1 of the QEGE experiment described in the attached main paper (Version 9). We will test whether controlled modulation of the entanglement participation factor p(r) = 1 + δ(r) produces measurable spacetime curvature via the linear-response relation δR ≈−8πGδρeff and the explicit weak-field metric ansatz given in §4 of the paper. The actuator is a programmable Rydberg atom array. The probe is a high-sensitivity cold-atom interferometer gradiometer with optional hybrid amplification (BEC overlap or levitated nanoparticle). The design directly verifies the positive-energy Class-I solutions, controlled interior time rate, dominant time-gradient mechanism, and the 50/50 temporal-spatial contribution to light deflection (Appendix B). The experiment is engineered to either detect the predicted effect or place a stringent upper bound, with full systematic control and statistical power analysis. Total requested funding: $2.8M over 3 years (leveraged model). Success would constitute the first laboratory evidence of engineered spacetime curvature and open a new experimental field at the quantum-gravity interface.
