Cosmic-shear weak-lensing surveys reveal an excess of B-mode power beyond what ΛCDM predicts from known sources, with unexpected spatial patterns and scale-dependence (Schneider 2002; Kilbinger 2013). The B-mode excess cannot be fully explained by observational systematics or known astrophysical sources (intrinsic alignments, source clustering), suggesting unanticipated mass distributions with rotational/vector components or modified lensing geometry.
The standard model expects gravitational lensing from scalar density perturbations to produce predominantly E-modes, with B-modes only from special configurations (multiple lens planes, rotational effects). The observed B-mode excess demands either modified lensing geometry, unexplained vector mass distributions, or unmodeled systematic effects, none of which is parsimonious.
SCT replaces the hot-dense-center with a superluminal collision and the thermalized debris field. From this single change, cosmic shear B-modes are gravitational-superposition + angular-momentum-inheritance signatures. Gravitational superposition (P50, P51, P52, P54) gives smoother halos with the Φ_mesh contribution that ΛCDM omits; the mesh contribution affects the lensing tensor in ways that produce small B-mode signals beyond pure scalar-perturbation predictions.
Cascade-J inheritance (P22, P31, P32) gives coherent rotational alignment of cosmic-web structures that contributes to the B-mode signal: the cascade-stream J-axis coherence across cosmic-web filaments imprints rotational components on the cluster + cosmic-web mass distributions, producing B-mode patterns that scale-invariant scalar-only models cannot reproduce. The shear B-mode signal aligns with the cascade J-axis (cross-link recid 162 quasar polarization 1 Gpc + recid 200 spin-filament alignment).
The same M6 + M3 framework that produces the A_lens excess (recid 16, 30), the cluster-substructure GGSL excess (recid 194), the weak-lensing peaks deficit (recid 226), the strong-lensing arc properties (recid 228), and the broader no-DM-particle phenomenology accounts for cosmic shear B-modes. Small B-mode signals are SCT-predicted natural signatures from coherent-mesh + cascade-J-inheritance contributions to the lensing tensor, not anomalies requiring beyond-ΛCDM physics.
If precision Euclid + LSST + Roman cosmic-shear B-mode measurements find B-modes fully consistent with standard scalar-perturbation predictions plus systematic-effect corrections at the 1% level (no Φ_mesh + cascade-J-inheritance signature), the M6 + M3 explanation is refuted. The signature SCT prediction is small B-mode signals scaling with the calibrated A factor + cascade-J-axis alignment indicators.
