The 18-State Tendency Classification in World Quantum Theory: A State-Space Coordinate Based on the Projection Coupling Factor x

Based on the core parameter of World Quantum Theory (WQT)—the projection coupling factor x—this paper proposes an 18-state classification framework. It is explicitly declared that this classification takes the Earth's surface (x ≈ 2π, g ≈ 9.81 m/s², geomagnetic field ~0.5 Gauss) as its observational projection layer. Different celestial bodies or artificial environments (e.g., the Sun, Moon, Mars, Casimir cavities) require a recalibration of the state coordinates. The framework uses the numerical segmentation of x (Eigenstate x=1, Electron State x=2π, Inner Domain 1<x<2π, Outer Domain x>2π) as its longitudinal axis, and wavelength (long/short), momentum (large/small), and closure (closed/open) as its latitudinal axes, to construct a unified state coordinate for describing the tendencies of particles/excited states. This classification is not intended to replace the standard nomenclature of existing particle physics, but rather to provide a common reference frame for different states: every known particle or excitation mode can find its "state address" within this coordinate system. The core insight of this framework is that x=2π (the Electron State) is not a universal constant, but a special closed reference state on the Earth's local projection layer; x=1 is the eigen-limit state, corresponding to ultimate convergence concepts like true black holes, absolute zero, and minimal particles; the eight states each in the inner and outer domains cover a continuous spectrum from open propagation to deep condensation. This classification directly interfaces with WQT's core prediction—that x deviates from 2π in SAA, Casimir cavities, and on the lunar surface—providing a clear state-coordinate map for experimental verification. This classification is applicable only to the Earth projection layer. In other environments, such as the Sun, the numerical values and segmentation boundaries of the state coordinates must be recalibrated.
