When quantum vacuum fluctuations enter a high-coherence phase, their energy adds constructively, creating extreme spacetime curvature per Einstein's field equations. At the proton’s core, this curvature forms an event horizon—a semi-permeable boundary that traps vacuum energy and creates a pressure and energy gradient. As coherence drops across this gradient, a second semi-permeable surface forms, further reducing energy and pressure. This behavior mirrors fluid dynamics and can be modeled using
