We present a complete theoretical framework demonstrating that rotating Kerr black holes naturally facilitate particle transitions between tiers of a quantized multiverse. The mechanism leverages the Kerr black hole’s unique geometry to create a catalytic “resonance zone” (rH < r ≤1.5M). Within this zone, the intense gravity perturbs the fundamental meta-field, and general-relativistic effects like frame-dragging and gravitational time dilation dramatically enhance the probability of a particle transitioning between universe-tiers. This particle-level process is catalyzed by the black hole environment, with the transition energy scale set by the fundamental GUT-scale gap ΔE~1016 GeV. The model yields specific, falsifiable predictions, including anomalous ultra-high-energy cosmic rays—from protons to heavy nuclei—emanating from directions of spinning black holes. Predicted fluxes are consistent with observations from the Pierre Auger Observatory and Telescope Array when accounting for instrumental coverage and source distribution. Furthermore, the mechanism is inherently bidirectional, enabling the detection of particles from other tiers and opening the possibility for opening the possibility for paradox-free cross-temporal transitions between parallel tiers.
