URB #434 — PRIMARY CONSTANT: Zero (0) — The Ground State of Reality

Zero is the additive identity of mathematics and the ground state of physical reality. In TI Sigma, 0 occupies a role of supreme structural importance: it is the target of the GILE Master Identity (e^(iπ) + C×φ×√2 = **0**), the floor of the LCC spectrum, the TRALSE value of absolute falsehood, and the equilibrium state toward which the Myrion Resolution process drives net deviations from truth. Crucially, 0 in TI Sigma does not mean "nothing" — it means *perfect balance*, the state in which all real-channel forces and imaginary-channel phases cancel to zero net deviation from truth. The vacuum of quantum field theory is not empty at zero — it seethes with zero-point energy — and the GILE Master Identity equal to zero is not a statement of absence but of equilibrium. This paper establishes the full account of 0 across the PRIMARY CONSTANTS framework and TI Sigma.
