Most of the matter of the universe is ``dark''. Based on the Schwarz viscous and turbulence self-gravitational condensation scales, most dark matter has two forms: ``primordial fog particles'' (PFPs---now moon-mass black dwarfs in galaxy halos) which condensed when the plasma universe neutralized to an inviscid, weakly-turbulent gas about 0.3 By (billion years after the big bang); plus WIMP fluids whose weakly-interacting-massive-particles may still be condensing slowly at large scales to form halos about galaxy clusters. Recent Hubble Space Telescope (HST) photos show evidence of PFPs as cometary globules in planetary nebulae (see http:www-acs.ucsd.edu ir118 for illustrations). Recent HST deep field photos show red galaxies existed at only 0.75 By, also suggesting a gentle, weak-turbulence, PFP condensation scenario for the first (small red) stars, within preexisting galaxy mass PFP ``fog patches''. The generally accepted Jeans criterion permits no such condensations of protogalaxies in the plasma epoch, and requires a strongly turbulent (big blue star) initial gas condensation scenario that is inconsistent with fossil non-turbulence evidence such as ancient globular star clusters and the extreme temperature uniformity observed in the cosmic microwave background radiation.
