Cross-Scale Validation of Prime-Indexed Information Geometry: From Cosmological Lorentz Anisotropy to Gravitational Wave Signatures

Recent observations across radio astronomy, large‑scale structure, and gravitational‑wave astrophysics reveal anomalies that challenge the standard ΛCDM paradigm. This work presents an integrated analysis within the Universal Model Framework (UMF), which models spacetime as an emergent prime‑indexed information lattice with fractal dimension D\approx 1.63. Using independent datasets—radio dipole measurements, LoTSS‑DR2 counts‑in‑cells statistics, angular clustering bias, BAO dilation, and a high‑resolution Maya E8 simulation of the GW170817 binary neutron star merger—we demonstrate quantitative cross‑scale consistency spanning over 60 orders of magnitude.We show that the radio source count dipole excess (3.67 ± 0.49 times the kinematic expectation) arises naturally from second‑order gravitational information flow while remaining compatible with local Lorentz invariance (RG‑17). LoTSS‑DR2 variance scaling implies D=1.80–2.05, consistent with UMF predictions once baryonic structure formation is included. The Maya E8 Holographic Engine reproduces all pre‑registered GW170817 criteria, including the Post‑Newtonian chirp exponent (−0.3750), echo delay \Delta t=8M\ln M with 98.2% agreement, and three prime‑harmonic spectral peaks at f_p=f_0\sqrt{p} for p=7,13,31.The convergence of cosmological, astrophysical, and computational signatures provides evidence for a unified prime‑indexed information geometry underlying spacetime. We conclude with a set of falsifiable predictions—including a quadrupole‑to‑dipole ratio C_2/C_1\approx 0.10, variance‑scaling transitions at 0.1°–10°, and prime‑frequency modes for future gravitational‑wave events—testable with LoTSS‑DR3, EMU, SKA, and LIGO O5.
