  The first structures were proto-voids formed in the primordial plasma.
Viscous and weak turbulence forces balanced gravitational forces when the scale
of causal connection at time 30,000 years matched the viscous and turbulent
Schwarz scales of hydro-gravitational theory (Gibson 1996). The photon
viscosity allows only weak turbulence from the Reynolds number Re = 200, with
fragmentation to give proto-supercluster voids, buoyancy forces, fossil
vorticity turbulence, and strong sonic damping. The expanding, cooling, plasma
continued fragmentation to proto-galaxy-mass with the density and
rate-of-strain preserved as fossils of the weak turbulence and first structure.
Turbulence fossilization by self-gravitational buoyancy explains the cosmic
microwave background temperature fluctuations, not sonic oscillations in
cold-dark-matter fragments. After plasma to gas transition at 300,000 years,
gas fragmentation occurred within the proto-galaxies to form
proto-globular-star-cluster (PGCs) clouds of small-planetary-mass
primordial-fog-particles (PFPs). Dark PGC clumps of frozen PFPs persist as the
inner-galaxy-halo dark matter, supporting Schild's 1996 quasar-microlensing
interpretation. Non-baryonic dark matter diffused into the plasma
proto-cluster-voids and later fragmented as outer-galaxy-halos at diffusive
Schwarz scales, indicating light, weakly-collisional fluid particles (possibly
neutrinos). Observations support the theory (Gibson and Schild 2003).
