Main Steps in the Big Wave Model
Step 1. We start with a Big Crunch. The ultimate result of the almost complete contraction of any single universe is a gigantic black hole located at the origin. If something strange didn't happen at that point, it would just stop there and never re-expand. I claim that the extreme gravitational attraction pulls the individual gravitons out of the basic unit masses composing the black hole (triquark crystal?), and then the energy equivalent of this mass is suddenly released as photons, along with a new entity related to the gravitons that I call a graviphoton, moving together in a propagating spherical wave. This was a net zero linear and angular momentum system before the universe creation event, and it remains so after the event by producing a spherically symmetric result with no rotation. If the photons move away together with the wave equivalent of the gravitons (graviphotons), both propagating at the speed of light, then the two components are spherically coherent in space.
Step 2. All that needs to be assumed is that the photons and graviphotons can recombine to form mass again, and that this process might follow a jo spherical Bessel wave function-squared that contains the pure characteristic wavelength of the graviphotons, which have a periodicity of about 800 million light years. If fast neutron formation results from this recombination while conserving both energy and momentum, and the neutrons decay to protons, electrons and neutrinos making a moving hot plasma annulus, then hydrogen, deuterium and helium would be deposited in a damped sinusoid-squared manner spherically outward from the origin. This explains the basic origin of the pattern of observed periodic "Great Walls" of galaxies.
Step 3. As the plasma cools below its ignition temperature, the electrons recombine to make neutral atoms and the photons continue to scatter, eventually producing the Cosmic Microwave Background everywhere in space.
Step 4. The observed strong local heterogeneity of galaxy locations is the result of other smaller black holes that didn't arrive in time for the "Big Wave" to form, and which then follow on behind the wave gathering new mass and becoming the seeds of galaxies. They can do this because the big gravity sink that once was located at the origin is no longer there to trap them. The existence of black hole seeds allows galaxies to form in a reasonable length of time, rather than having to wait for random motions to start the process.
