Query: Phenomenological scaling laws relating the observed galactic dimensions
  to Planck action constant   It is shown that the characteristic observed radius, velocity, and
temperature of a typical galaxy can be inferred from Planck action constant
through a phenomenological scaling law on all cosmological scales.
