        I think it's more complicated than that, depending upon the
distribution and temperature of the dark matter.  If the solar system
is immersed in a sea of dark matter then the sea correlates only
roughly with the observed distribution of ordinary hadronic matter.
        Nucleosynthesis arguments, based on big-bang theory, seem to
indicate that dark (non-hadronic matter) predominates almost everywhere
(possibly excepting Kansas).
