Geometric Accretion Limits in Early Universe Supermassive Black Holes: A Falsifiable Prediction from Information Tension Theory

Background. The James Webb Space Telescope (JWST) has revealed overmassive early-universe galaxies and Direct Collapse Black Holes (DCBHs) whose rapid assembly defies ΛCDM accretion timelines. Standard radiation-pressure dynamics, bounded by the Thorne limit (a* = 0.998), predict catastrophic radiative blow-out that starves the hyper-Eddington accretion required to reach 10^7–10^8 solar masses within 500 Myr of the Big Bang. Framework. We present a resolution via the Geometric Ordered Dynamics (GOD) framework and Information Tension Theory (ITT). By replacing dark matter with a structural Information Tension Tensor (T_μν), we show that vacuum topology inherently limits accretion kinematics. We establish a deterministic spin corridor for early DCBHs bounded by the vacuum’s base accretion capacity (χ_lower = 0.1298 → a* ≈ 0.83, η = 12.98%, r_ISCO = 2.75M) and the sovereign stability bound (χ_sovereign = 0.9539 → a* ≈ 0.954, η = 19.4%, r_ISCO = 1.90M). Above a* = 0.954 the Information Tension field exceeds its geometric stress tolerance and loses coherence, superseding the classical Thorne limit. Empirical anchor and prediction. The framework is anchored by one empirical measurement: the chiral invariant χ ≈ 0.1298 derived from real JWST NIRSpec spectra (CEERS program 1345, EGS field) via mean normalized flux across wavelength channels. From this anchor the framework predicts a stellar-mass excess of order ~141 for the most extreme overmassive early galaxies relative to the ΛCDM stellar-mass maximum. This ~141 figure was originally motivated by the photometric candidate CEERS-93316 (z ≈ 16.7), which was subsequently spectroscopically reclassified to z ≈ 4.9 (Arrabal Haro et al. 2023) and is therefore no longer presented as a confirmed observation but as a falsifiable theoretical prediction awaiting a dedicated high-redshift spectroscopic survey. Falsifiable prediction. The narrow corridor width Δa* = 0.124 yields decisive statistical power. Under the conservative ΛCDM null hypothesis (spins uniform on [0, 0.998], p_null = 12.43%), a cumulative binomial test gives: 10 of 10 corridor matches → p = 8.8 × 10^-10 (6.0σ); 11 of 15 matches → p = 5.2 × 10^-8 (5.2σ, allowing 4 outliers for measurement uncertainty); 15 of 15 matches → p = 2.6 × 10^-14 (7.5σ). The Laser Interferometer Space Antenna (LISA) will test this directly via gravitational-wave ringdown spectroscopy of high-redshift SMBH mergers. License. CC-BY-4.0.
