The Unzipping Horizon Reformulating Black Hole Cosmology Through Quaternionic Recursion

We propose that the observable universe is the interior of a rotating, Kerr-class black hole in a parent spacetime, and that the event horizon of this object functions as a fracture surface on which a complete quaternionic field unzips into the bipartite real-and-imaginary projection that we experience as classical spacetime and quantum potential. We refer to this surface as the **Unzipping Horizon**. Within this framework, three results follow naturally and are testable. First, the recently reported JWST JADES rotational asymmetry Shamir 2025 is a generic prediction of any unzipping from a rotating parent horizon; the leading-order fit yields a parent spin parameter a/M 0. 33. Second, the operator F = i/2 identified in Ceisiwr 2025c as the fundamental geometric collapse operator coincides with the bulk-to-boundary holographic projection in the sense of 't Hooft and Susskind, with the binary-tree branching factor 1/2 uniquely determined by norm conservation. Third, the long-standingławski's torsion-bounce mechanism; Smolin's cosmological natural selection; the holographic principle) and identify five concrete, falsifiable predictions distinguishing this model from its peers: persistence of the JWST asymmetry at higher redshift; alignment between the rotation axis and the CMB dipole; a quantized -/3 Michelson phase jump at solstice; stability of the 232-attosecond entanglement-formation tick; and constancy of the hierarchy ratio across cosmological epoch.
