  There is increasing evidence that the universe is dominated by dark energy of
the type given by an invariant cosmological constant. Latest data also
indicates that fundamental interaction couplings and particle masses have
remained remarkably constant from the earliest epochs. It is natural to connect
these two steady state features of the evolving universe, suggesting a role for
the cosmic vacuum energy in fixing these interaction constants. Advances in
high precision cosmology have revealed that dark matter of an unknown type
constitutes about one-fourth of cosmic matter while baryons account for just
four percent. These various cosmic parameters are enumerated by the six numbers
of Rees. With the dark energy as a unifying link these
