Actinoide Arc (Dust?)

The Actinoide Arc — a large, coherent arc-like overdensity of galaxies spanning hundreds of megaparsecs — presents a structural challenge for standard cosmology because features of that angular scale and spatial coherence are not expected to arise from the small-amplitude Gaussian perturbations that ΛCDM seeds with inflation. Successive Collision Theory addresses this directly through collision geometry: when two immense spacetime pockets intersect with a non-zero impact parameter, the swept collision front does not deposit energy uniformly. Instead, the geometric intersection of two curved pocket boundaries naturally produces crescent- and arc-shaped compression zones where thermalized matter-energy density is locally elevated above the mean. The Actinoide Arc is, in this framework, a fossilized imprint of one such collision-front arc, preserved in the large-scale galaxy distribution.

The persistence and coherence of this arc over cosmic time is further explained by angular momentum inheritance. The collision deposits a specific angular momentum vector aligned with the impact geometry; matter along the arc is preferentially on trajectories that carry inherited angular momentum from the original pocket intersection. This keeps the arc structurally distinct from its surroundings — it does not dissolve into the background density field the way a random Gaussian fluctuation would, because the angular momentum barrier maintains coherent flow along the arc's curvature. The dust interpretation offered by some observers may be partially correct as a foreground contaminant, but SCT predicts a genuine underlying large-scale matter overdensity at the arc's location, sourced by collision geometry rather than by inflationary perturbation amplification.
