  ABSTRACT: We investigate the influence of the Hubble parameter H( z ) on galactic dynamics and morphology. By introducing the cosmic expansion as an effective limit on Newtonian gravitation, we obtain a redshift-dependent critical radius that constrains both spiral structure and rotation curves. Galactic bars are interpreted as frozen spirals of high- z epochs nested inside extended low- z spirals. This framework naturally explains the coexistence of bulges, bars, disks and halos as the outcome of metric inflow and bulge reset events. The resulting morphology and kinematics provide a direct and testable connection between galactic structure and the cosmic expansion. We argue that this approach opens a new possibility to empirically derive H( z ) from galaxy morphology and rotation curves and allows reconstructing the expansion history of the universe on galactic scales.
