The void size function, depth distribution, internal profiles, and evolution show discrepancies with ΛCDM N-body simulations and analytic models (Sheth & van de Weygaert 2004; Nadathur & Hotchkiss 2015; Sutter 2014; Hamaus 2014). Real voids appear larger, more abundant, and significantly emptier (lower density contrast) than dark-matter simulations predict. The mismatch is broad and persistent.
The standard model predicts the void size function and density profiles based on growth of structure from Gaussian initial fluctuations. Real voids exceeding model predictions in abundance, size, and emptiness simultaneously demands tuned galaxy bias, modified feedback, or different initial spectra. None reproduces all three signatures cleanly within minimal ΛCDM.
SCT replaces the hot-dense-center with a superluminal collision and the thermalized debris field. From this single change, the joint void statistics (abundance + depth + shape asymmetry) reduce to a single cascade-stream geometry signature. Voids are inevitable inter-filament regions of the cascade-deposited cosmic web (P22, P34), with the cascade impact-parameter distribution P(b) ∝ b setting the population demographics.
Predicted abundance: roughly 5 to 10 KBC-amplitude supervoids per observable patch (recid 95), with size distribution N(R) ∝ R^(−1.4 to −1.6). Predicted interior depth: roughly 25% deeper than the Gaussian-initial-condition prediction, sourced by enhanced Λ_eff inside voids (P17, P19) plus mesh dissipation (P14, P15, P16) over cosmic time (P18). Predicted shape asymmetry: voids are slightly elongated along the cascade J-axis direction (P31, P32), aligning with the cascade-stream geometry of the bounding filaments.
All three observational mismatches reduce to the same SCT framework. The KBC, Eridanus, Local Supervoid, and broader supervoid population (recids 86, 89, 90, 95) all share this cascade-stream origin. The same M4 framework that produces the cosmic-web morphology, the gigaparsec ring-and-arc structures (recid 85), and the wall demographics (recid 94) produces the void statistics. There is no need to tune galaxy bias, modify feedback, or invoke non-Gaussian initial conditions.
If precision DESI + Euclid + SKA void surveys find the size function, depth distribution, AND shape asymmetry simultaneously consistent with ΛCDM Gaussian-tail predictions at the 1% level, the M4 cascade-stream void-origin explanation is refuted. The signature SCT prediction is the joint three-feature signature emerging from a single cascade-deposited geometric mechanism rather than from three separately tuned subsidiary parameters.
