As the result, observable matter has condensed both into sparse particle clouds, both into dense overheated droplets of metastable matter, so called quasars, sitting in the nodes of resulting foamy structure of dark matter. The finely divided matter has formed small galaxies and stellar clusters without central black holes by mechanism of gradual gravitational collapse, which doesn't differ significantly from contemporary mainstream cosmology. But the formation of large galaxies was completely different by AWT.
After releasing of pressure, quasars have started to evaporate their excessive matter into radiation, which has condensed partially near quasars, whenever the intensity of gravitational field has decreased bellow certain value. The quasars were surrounded by particles of matter and antimatter, which have exchanged their mass by radiation on behalf of observable matter. The resulting particles were formed by atom nuclei up to silicon, which recombined with electrons under formation of heavy clouds of dense dust, surrounding the active galactic nuclei. The particles of dust were kept at the safe distance by radiative pressure of central quasars inside it. The newly formed galaxies were of spherical shape and they were only slightly radiative because of strong light absorption by dust particles.
The dual AWT cosmology is based on understanding, the observable matter is metastable phase in contact with vacuum and it has tendency to evaporate at elevated temperature and/or gravity field intensity. Therefore the matter must be formed by another mechanism and the black holes can play an active role in it. In addition, a recent observation supports the above model by presence of giant black holes and sparsely distributed, but well developed galaxies composed of heavy elements even at the most distant/old parts of Universe. This model considers upper limit of giant black holes, above which the matter is radiated, not swallowed by black holes. This upper limit follows from modified theory of gravity, the quantum gravity in particular, as predicted by AWT.
Remark 1: This idea was originally presented before three years and it was recently disputed in Nature News and NewScientist article, so it belongs into testable predictions of AWT, because we can observe remnants of this process both by stars formation near black hole inside of our gallaxy, both by galaxies formation near distant qausars.
Remark 2: This idea has relevance to so called shock wave cosmology of black holes, as proposed by J. Smoller and B. Temple [PNAS, 2002]. I hope, these connections will make whole stuff more interesting for the rest of cosmologists.
Remark 3: While cosmologists are aware of the fact, the brane collisions should left some traces on CMB background, it seems, nobody tried to connect the foamy structure of dark matter with is concept of penetrating branes - supposedly because nobody has considered their material nature and because ekpyrotic cosmology is illustrated quite abstract and meaningless way.
Remark 4: Anonymous barkster user has noted a simmilarity of black hole jets with jets formed by collision of water (mem)branes. This connection has really some relevance here, as by AWT black hole jets are temporal artifacts too and it can be interpreted as a product of spontaneous symmetry breaking of event horizon.
