সূচিপত্রের সারণি:
- <p>We present Structural Differentiation Cosmology (SDC) v1.2, a minimal and falsifiable framework in which cosmological observables arise as projections of irreversible structural differentiation within a closed relational system.</p> <p>In contrast to standard cosmology, SDC does not introduce additional physical components such as dark energy. Instead, it reinterprets observed phenomena as consequences of internal structural evolution.</p> <p>We demonstrate that SDC reproduces the observed expansion history H(z) with near-degeneracy relative to ΛCDM, while simultaneously predicting a systematic suppression in structure growth fσ₈(z).</p> <p>This separation leads to a key observational insight:</p> <p>Background expansion alone does not uniquely determine the underlying physical mechanism.</p> <p>To resolve this degeneracy, we introduce the Geometry–Growth Projection Test (GGPT), a unified diagnostic in the (ΔH/H, Δ(fσ₈)/(fσ₈)) plane.</p> <p>This provides:</p> <p>A single decisive and directly testable observational criterion distinguishing structural projection cosmology from physical acceleration models.</p> <p>We further show that both expansion and growth are governed by a single structural variable C(z), establishing a unified dynamical origin.</p> <p>Key result:<br>Geometry agrees, but growth reveals the underlying structure.</p> <p>SDC therefore shifts cosmology from an energy-component description to a structural evolution description, providing a direct and testable bridge between theory and observation.</p>
