Turbulence and turbulent mixing in natural fluids
Turbulence and turbulent mixing in natural fluids begins with big bang
turbulence powered by spinning combustible combinations of Planck particles and
Planck antiparticles. Particle prograde accretions on a spinning pair releases
42% of the particle rest mass energy to produce more fuel for turbulent
combustion. Negative viscous stresses and negative turbulence stresses work
against gravity, extracting mass-energy and space-time from the vacuum.
Turbulence mixes cooling temperatures until strong-force viscous stresses
freeze out turbulent mixing patterns as the first fossil turbulence. Cosmic
microwave background temperature anisotropies show big bang turbulence fossils
along with fossils of weak plasma turbulence triggered as plasma photon-viscous
forces permit gravitational fragmentation on supercluster to galaxy mass
scales. Turbulent morphologies and viscous-turbulent lengths appear as linear
gas-proto-galaxy-clusters in the Hubble ultra-deep-field at z~7. Proto-galaxies
fragment into Jeans-mass-clumps of primordial-gas-planets at decoupling: the
dark matter of galaxies. Shortly after the plasma to gas transition,
planet-mergers produce stars that explode on overfeeding to fertilize and
distribute the first life.Comment: 23 pages 12 figures, Turbulent Mixing and Beyond 2009 International

Do micro brown dwarf detections explain the galactic dark matter?
Context: The baryonic dark matter dominating the structures of galaxies is
widely considered as mysterious, but hints for it have been in fact detected in
several astronomical observations at optical, infrared, and radio wavelengths.
We call attention to the nature of galaxy merging, the observed rapid
microlensing of a quasar, the detection of "cometary knots" in planetary
nebulae, and the Lyman-alpha clouds as optical phenomena revealing the compact
objects. Radio observations of "extreme scattering events" and "parabolic arcs"
and microwave observations of "cold dust cirrus" clouds are observed at 15 - 20
K temperatures are till now not considered in a unifying picture. Aims: The
theory of gravitational hydrodynamics predicts galactic dark matter arises from
Jeans clusters that are made up of almost a trillion micro brown dwarfs (mBDs)
of earth weight. It is intended to explain the aforementioned anomalous
observations and to make predictions within this framework. Methods: We employ
analytical isothermal modeling to estimate various effects. Results: Estimates
of their total number show that they comprise enough mass to constitute the
missing baryonic matter. Mysterious radio events are explained by mBD pair
merging in the Galaxy. The "dust" temperature of cold galaxy halos arises from
a thermostat setting due to a slow release of latent heat at the 14 K gas to
solid transition at the mBD surface. The proportionality of the central black
hole mass of a galaxy and its number of globular clusters is explained. The
visibility of an early galaxy at redshift 8.6 is obvious with most hydrogen
locked up in mBDs. Conclusions: Numerical simulations of various steps would
further test the approach. It looks promising to redo MACHO searches against
the Magellanic clouds.Comment: 12 pages A&A tex, 3 pdf figure
