Anthony Peratt, a specialist in plasma phenomena, writes, “a shock pulse initiates a series of hydrodynamic instabilities that differ from the plasma column instabilities. In hydrodynamics, these are the Richtmeyer-Meshkov instabilities recorded by Budzinskii and Benjamin … Initially, a pulsed perturbation on a denser layer causes a rippling of the layer that rapidly develops into periodically spaced spike like features. These features, or 'spikes' then evolve … the shock impulse causes the generation of yet more instability spikes that themselves morph into yet more complex instability shapes.”
I know this doesn't sound very genealogical...but it all has something to do with whether or not your ancestors were stacked.
I was with the article up until the last paragraph, then I got lost.
update: With a little more time to do some research I have found some information on the theory behind the connection between mythology and plasma. It is certainly a fascinating concept, though I have no inkling how far in or out of the scientific mainstream it is. (Beyond the low number of Google hits for 'Auroral Pillar')
