  A quantum gravitational instability is identified at Planck scales between
non-spinning extreme Schwarzschild black holes and spinning extreme Kerr black
holes, which produces a turbulent Planck particle gas. Planck inertial vortex
forces balance gravitational forces as the Planck turbulence cascades to larger
scales and the universe expands and cools. Turbulent mixing of temperature
fluctuations and viscous dissipation of turbulent kinetic energy provide
irreversibilities necessary to sustain the process to the strong force freeze
out temperature where inflation begins. Turbulent temperature fluctuations are
fossilized when they are stretched by inflation beyond the horizon scale of
causal connection. As the horizon of the expanding universe grows, the
fluctuations seed patterns of nucleosynthesis, and these seed the formation of
structure in the plasma epoch. Fossil big bang turbulence is supported by
extended self similarity coefficients computed for cosmic microwave background
temperature anisotropies that match those for high Reynolds number turbulence.
