On hierarchial cosmology

The paradigm transition in cosmic plasma physics towards inhomogeneous models with features such as double layers, cell walls and filaments is discussed. A model ('Fireworks model') which accounts for the void region between the de Vaucouleurs (dV) and Laplace-Swarzchild limits is outlined. A hierarchical structure results from the explosion of a developing structure which reaches the dV limit. The explosion of this primary cloud, or protometagalaxy, causes metagalactic expansion. The largest fragments become protosuperclusters, which explode emitting protoclusters, which similarly form galaxies. Annihilation is a likely energy source for the explosions. In a cosmic cloud consisting of koinomatter and antimatter separated by Leidenfrost layers, a stationary equilibrium requires that n1/nS = VS/V1, where n1 is the density of the annihilation electrons, V1 their temperature in the Leidenfrost layer, and nS and n1 are the corresponding values in the slabs of matter. If VS becomes comparable to V1, the Leidenfrost layer cannot operate efficiently, so general annihilation, resulting in an explosion, occurs.
