Version 2.0 — Major Revision (January 2026) This revision incorporates observational evidence supporting the theoretical predictions of the Dual Homology framework. Key changes include: Added observational motivation: Cited recent studies (Ricciardelli et al. 2014; Cautun et al. 2016) showing that observed void density profiles are significantly steeper than ΛCDM simulations predict, with sharp density ridges at void boundaries. Clarified physical interpretation: The coupling constant α in the field tension definition is now explicitly interpreted as the fluctuation-to-structure coupling efficiency. Strengthened core thesis: The background-state description now explicitly states that "spacetime itself ceases to emerge as a dynamical structure" when field fluctuations vanish, reflecting the original theoretical intuition more directly. Expanded Discussion section: Added comparison with observational evidence, theoretical implications, and future directions including Euclid and Vera Rubin Observatory predictions. Enhanced Conclusion: Summarized the falsifiable predictions and preliminary observational support. Fixed references: Corrected broken citation links and added new references. Version 1.0 — This work explores cosmic voids as local probes of the simplest physicalstates accessible within the observable Universe. Within the Field-Fluctuation Universe (FFU) framework, void interiors areinterpreted not merely as underdense regions, but as outcomes of tensioncollapse and connectivity regression in the underlying field network. The paper introduces a Dual Homology framework, proposing that deep voidinteriors represent the only observationally accessible realization of thebackground-state regime expected beyond the observable Universe, while voidboundaries act as structural transition interfaces rather than physicalhorizons. Testable observational predictions are discussed, including fluctuationvariance suppression, weak lensing signatures of residual filaments, and thedynamics of void dwarf galaxies. This version is archived on Zenodo as a permanent research record, documentingboth the theoretical framework and the methodological context in which thestudy was developed.
