Mechanical Resolution of the Cosmological Constant Problem (Vacuum Catastrophe) via the UST Model

This paper provides a mechanical resolution to the Cosmological Constant Problem (Vacuum Catastrophe), addressing the 10¹²⁰ discrepancy between Quantum Field Theory (QFT) predictions and astronomical observations. Utilizing the Universal Sheet Tension (UST) Model, we propose a "Pressure Relocation" mechanism. We demonstrate that the high energy density predicted by QFT is not an intrinsic property of the 1D vacuum substrate, but rather the internal mechanical pressure (Pᵢₙₜ) localized within 3D matter inclusions required to maintain Young-Laplace equilibrium against 2D manifold tension (τ). This shift in classification resolves the paradox without the need for dark energy or fine-tuning.
