Dipole patterns inferred from galaxy number counts, radio and quasar surveys, and peculiar-velocity fields are systematically larger in amplitude than the kinematic CMB dipole (Secrest 2021; Colin 2017; Singal 2011). Matter and source-count dipoles exceed the kinematic expectation by factors of 2 to 4 while remaining broadly aligned in direction, suggesting either that matter and radiation rest frames do not coincide or that there is intrinsic large-scale anisotropy.
The standard model assumes the CMB dipole is purely kinematic, produced by our motion through the otherwise statistically isotropic FLRW universe. Matter dipoles must therefore equal the CMB dipole. A persistent 2-4x amplitude excess implies either rest-frame coincidence breakdown or intrinsic anisotropy, neither of which has place in the model.
SCT replaces the hot-dense-center with a superluminal collision and the thermalized debris field. From this single change, the local dipole anomaly decomposes into three predicted components with distinct geometric signatures. The first is the kinematic dipole D_kin ≈ 0.005 aligned with the CMB dipole, sourced by our patch's residual frame velocity within the parent frame (P63). The second is a cascade-J component perpendicular to D_kin, sourced by angular-momentum inheritance from the cascade impact-parameter geometry (P31, P32, P64). The third is a Λ_eff/KBC component along the supervoid axis, sourced by the dynamical Λ_eff field (P17, P19).
The total observed amplitude exceeds D_kin alone by 50 to 100%, matching the observed galaxy/quasar/kSZ dipole excess across multiple wavelengths. Sibling-pocket gravitational influence at 1 to 2 Gpc separations (P58, P59, P60) adds a smaller fourth contribution. The geometric requirement P64 (J perpendicular to b, with v_frame parallel to b) means the kinematic and cascade-J components should be approximately perpendicular, which is testable by directional decomposition of multi-wavelength dipole data.
The same M9 framework that produces dark flow (recid 12), the CMB dipole excess (recid 31), the galaxy distribution dipole (recid 77), and the bulk-flow excess (recid 87) produces the local dipole anomaly. Each is a different observational projection of the same multi-pocket cascade-geometry signature. There is no need to invoke matter-radiation rest-frame breakdown or intrinsic large-scale anisotropy beyond cascade-geometry effects.
If next-generation multi-wavelength dipole analyses with full directional decomposition find galaxy dipole consistent with the kinematic CMB dipole at the 5% level (no perpendicular cascade-J component, no supervoid-aligned Λ_eff component), the M9 sibling-pocket plus cascade-axis explanation is refuted. The signature SCT prediction is approximately 90-degree separation between the kinematic component and the cascade-J component.
