Rather than "condensation begins" it might be better to say "fragmentation begins" at about 10^12 seconds (30,000 years) in the slide. Condensation is opposed by the expansion of the universe, so that the baryonic density of 10^-17 kg m^- 3 existing at this early time (from Einstein's equations, S. Weinberg 1972) in the fragments of plasma will not increase as the density of protosuperclustervoids between them decreases. This protosupercluster plasma density 10^-17 kg m^-3 is preserved as a fossil of the non-turbulence at this time of first structure, and appears as the density of globular star clusters in slide 13. The dark matter of the inner halo of galaxies (within about 10^21 m of the core) has about 30 times the mass of the luminous stars, and is comprised of protoglobularstarcluster (PGC) clumps of frozen hydrogenous planetoids (PFPs, rogue planets, Neptunes) according to Gibson 1996 and Schild 1996, with fossil density (non-)turbulence 10^-17 kg m^-3. For comparison, a "hard" laboratory vacuum on Earth produces a gas density of no less than 10^-15 kg m^-3.
