Black Holes as Cosmic Subdivision Devices: Boundary-Induced Sectorization, Polarity Accumulation, and Layered Structure of the Universe

This paper proposes a reinterpretation of black holes as cosmic subdivision devices rather than terminal gravitational sinks.In this framework, black holes are treated as boundary structures that enforce conditional separability of spacetime sectors. The accumulation of such single-polarity boundaries across spacetime is shown to be inherently unstable, leading to symmetry breaking, bipolarization, and inter-sector interference.The Einstein–Rosen bridge is redefined as a boundary collapse interface where strict sector separation fails and effective coupling emerges. This transition provides a structural mechanism for hierarchical organization across scales, connecting local spatial structure and global cosmological patterns without introducing new fundamental laws.Entropy growth is interpreted as a logarithmic increase in effective spacetime subdivisions, linking thermodynamic behavior directly to boundary accumulation rather than information loss.By treating spatial and cosmic layers as scale-dependent descriptions of a unified boundary process, this work offers a conceptual framework connecting black holes, entropy, large-scale anisotropy, and cosmic structure formation.
