The Jeans criterion for the minimum self-gravitational condensation scale is\nextended to include the possibility of condensation on non-acoustic density\nnuclei at Schwarz scales, where structure formation begins in the plasma epoch\nat proto-supercluster masses about 10,000 years after the Big Bang, decreasing\nto galaxy masses at 300,000 years. Then the plasma universe became relatively\ninviscid gas and condensed to 1023-26 kg "primordial fog particle" (PFP)\nmasses. Baryonic dark matter by this theory should be mostly non-aggregated\nPFPs that persist in galactic halos. Schild (1996) suggests from quasar\nQ0957+561 microlensing that "rogue planets" are "likely to be the missing mass"\nof the lens galaxy. Non-baryonic dark matter composed of weakly interacting\nmassive particles (WIMPs) should condense slowly at large viscous Schwarz\nscales to form galaxy supercluster halos, and massive galaxy cluster halos as\nobserved by Tyson and Fischer (1995) for the rich galaxy cluster Abel 1689.\n
