A hypothesis of curvature pressure is used to derive a static and stable
cosmology with a tired-light redshift. The idea is that the high energy
particles in the inter-galactic medium do not travel along geodesics because of
the strong electrostatic forces. The result is a reaction back on the medium
that is seen as an additional pressure. Combined with the explanation of the
Hubble redshift as a gravitational interaction results in a static and stable
cosmology. The predicted Hubble constant is 60.2 km/s/Mpc, the predicted
background microwave temperature is 3 degrees and quasar luminosity functions
and angular size distributions are shown to be consistent with the model. Since
most observations that imply dark matter rely on redshift data it is argued
that there is no dark matter. Observations of quasar absorption lines,
supernovae light curves and the Butcher-Oemler effect are discussed. The
curvature pressure is important for stellar structure and may explain the solar
neutrino deficiency.Comment: 27 pages, no figures. This is a rewritten version of astro-ph/9803009
