Fireball; deterministic chaos; optical emission flash – model for recombination and beginning of Dark Age?

Was the Russian meteor fireball like a plasma sphere, essentially? A charged fluid? Was it slowed down secondary to just aerodynamic enlarging shape, together with vastly dissimilar surfaces? What was the pressure in such brane? In a variation on a theme, would the collision of two pressurized brane fireballs serve as a model for Big Bang?

For such fireball event, kinetic energy seemingly is transformed into heat. What chemistry was occurring? Breaking of strong N_2 molecule, CO_2, and O_2 , and H_2O bonds, for higher temperature, even thousands of degrees. Would the fireball serve as a simulation for how long after Big Bang? One would have highly reactive oxygen atoms interacting with other atoms, in addition to any solid matter (filament like analogy?). Is luminosity of fireball in part from Lyman alpha emission from fully ionized hydrogen? That is, at higher temperatures, one has dissociation of molecules into atoms, such as for nitrogen, oxygen, carbon, and hydrogen.

Then might the optical flash from fireball (likewise for fission, fusion explosions, and re-combination?) be from de-excitation from ionization hydrogen (Lyman alpha emission?) ? Thus is temperature of Russian fireball, indirectly determined as the same as for re-combination (~3000 K?); the former then a simulation for the latter? Is then such optical emission spike for fission and fusion explosions, Russian fireball, the same as for optical emission spike commencing Dark Age? Exothermic reaction from molecular formation would seem to be of lesser effect. Might ambient air (nitrogen and oxygen) serve as additional fuel and oxidant respectively, giving resultant oxygenation? HCN nitrogen fixation; but not enough accumulation for any significant contribution to origin of life?

Recently (Feb 15, 2013), object (2012DA14) (1) came within 27,700 km of earth; inside geo-synchronous satellites’ altitude. Might mentioned supposed 22 meter diameter equivalent object be a left-over from proto-earth and planetesimal collision 4.5 byrs ago, and hence intersecting orbits eventually (see NEO blog, page 5)? At such close range in earth’s potential gravitational field, there must have been perturbation of it’s trajectory, and hence further significant geodesic deviation over a longer elliptical solar orbit. Might it’s recent pass by be considered as like ‘initial conditions’ together with small deviations? Then for such close encounters, one would have further visiting of a greater phase space; hence a deterministic chaos appearance? Thus eventual assured intersection with earth’s orbit; perhaps sooner? Likewise eventually for all other members of such data set? How large (smaller, if same trajectory determination) is the set to which such object belongs, assuming relatedness to ancient planets’ collision ~4.5 Byrs ago?  TMM
