The Resonant Gravity Framework (MJP Gravity) A Curvature-Triggered Two-Phase Model of Spacetime

We present the MJP Resonant Gravity framework, a minimal curvature-driven extension of General Relativity in which spacetime undergoes a two-phase transition depending on the Kretschmann scalar. When curvature exceeds a critical threshold, a resonant scalar mode becomes active and replaces the classical singularity with a finite-curvature core, recovering regular black-hole interiors while preserving Einsteinian geometry elsewhere. This preprint introduces the effective action, the modified field equations, and the resonance activation condition, and discusses implications for black-hole physics and quantum-gravity phenomenology.
