A Morphological Classification of Galactic Rotation Curves: Evidence for a Universal Evolutionary Sequence

Authors: Vakhtang MchedliSvili

We present a systematic morphological analysis of 175 galactic rotation curves from the SPARC database. We introduce a unified geometric metric, the Alpha Angle (α), to quantify dynamical maturity. Results reveal a strong correlation (R=0.89) between α and sSFR, yet identify anomalies (NGC 2841, F574-2) that challenge SFR as an absolute clock. We propose a mechanical model where galaxies undergo secular expansion due to mass loss ($dot{r}/r = -dot{M}/M$). The derived local expansion rate matches the Hubble constant ($H_0$), suggesting cosmic expansion as an emergent property of local mechanical relaxation.
