Twin-Complex Cosmology:Episode VI — Apparent Acceleration

This episode analyzes the conditions under which apparent accelerationarises in the twin-complex framework. Although the internal expansionmay be non-accelerating, the projected scale factor$a_{\mathrm{obs}}(t) = a(t) + b(t)$ can exhibit curvature that mimicsdark-energy-like behavior. The observable Hubble parameter inheritscurvature from both internal components, revealing that apparentacceleration is a geometric effect of projection rather than a dynamicalrequirement.
