This study reinterprets black holes as electromagnetic rotational bodies, addressing the limitations of conventional gravity-centered spacetime curvature theories that are insufficient to fully explain the darkness, rotational dynamics, and matter-distribution characteristics of black holes. In the terminal evolutionary stage of supermassive stars, a rapid thermal contraction occurs due to a drastic decline in nuclear fusion efficiency. Conservation of angular momentum consequently induces an explosive increase in rotational velocity, leading to extreme electron-density accumulation and magnetic saturation. In particular, the formation of a lead (Pb)–dominated ultra–heavy-metal outer shell generates a fully isolated electromagnetic boundary layer that blocks all incident light and signals, resulting in the absolute observational darkness of black holes. Furthermore, sequential fragmentation and gravitational-wave emission during cluster rotation of black holes, followed by redistribution of expelled material onto galactic disks, suggest that the universe operates as a rotation-driven material reactivation system (Re-Genesis). This study proposes that black holes are not mere gravitational singularities but function as electromagnetic rotational engines guiding galactic dynamics and matter evolution, establishing a multidisciplinary paradigm for the interpretation of black holes.
