Part 24: Effective Dark Collapse, Radiation-Feedback Suppression, and Gravitational-Wave-Like Bulk Oscillations in Origin Geometry

The existence of supermassive black holes at high redshift presents a longstanding challenge for conventional accretion models because growth rates are constrained by radiation feedback associated with the Eddington limit. Within the framework of Origin Geometry (OG), we investigate the possibility that a topological sector may exist in which electromagnetic coupling becomes strongly suppressed and excitations approach an effective near-flat-band regime. Within such regimes, electromagnetic radiation pressure may be substantially reduced due to the combined effects of suppressed electromagnetic transitions, weak photon coupling, and effective topological transparency within the dark sector. The present work proposes a mechanism of effective dark collapse in which dark-sector structures undergo gravitational collapse under significantly reduced radiative feedback compared with ordinary baryonic systems. As topological density increases, strongly pinned structures may experience local topological thawing, allowing the emergence of effective dynamical excitations analogous to plasma-like collective states. Nevertheless, electromagnetic relaxation remains strongly suppressed because photon accessibility continues to be limited. Within the coarse-grained description of Origin Geometry, a significant fraction of the released relaxation energy may couple preferentially to collective oscillations of the underlying geometric substrate. These bulk excitations may admit an effective gravitational-wave-like interpretation and may occupy extremely high-frequency regimes. The present framework does not identify such excitations directly with gravitational waves in General Relativity. Instead, they are investigated as a phenomenological mechanism for non-electromagnetic energy relaxation within the dual-sector geometric network.
