Data-Driven Refinement of the Q-Field Decay Exponent in Interstellar Object 3I/ATLAS (C/2025 N1): From β = 0.85 to β = 1/3 — A Turbulent Magnetic-Analog Framework

Based on high-precision measurements of the non-gravitational acceleration of interstellar object 3I/ATLAS (C/2025 N1) at perihelion (0.84 AU) and Jupiter flyby (5.2 AU), we determine that the Q-field intensity Q(r) = a⊥/v follows a strict power-law decay with exponent β = 1/3. This is in exact agreement with the real-space decay index derived from the random magnetic field annihilation mechanism in MHD turbulence, and deviates less than 0.5% from observation. The Q-field is thus identified as a solenoidal vector field (vortex field) — a dark-matter-polarization analog of the magnetic field — whose dynamics are governed by the same statistical laws as MHD turbulent cascades. We correct the decay exponent β = 0.85 of the original paper (which misapplied the wavenumber-space spectral index to real space) and derive the correct relationship: for Kolmogorov turbulence E(k) ∝ k⁻⁵ᐟ³, the real-space decay exponent is β = (α-1)/2 = 1/3. Precise forward predictions are given for 3I/ATLAS at 10, 20, 50, 100, and 353 AU, providing immediately falsifiable observational targets. The core framework of STLT and Witten axion wormhole topological quantization is preserved; only the spatial decay exponent is updated.
