From the geocentric, to the heliocentric and back to the unicentric model of the observable universe

Abstract

Human history is rich in suggestions and adoptions of models for the universe, but most of them did not pass the verification tests.
Starting with the geocentric, followed by the heliocentric and then by the current standard model of cosmology. The latter is mathematically and physically
a highly sophisticated model, which relies on, among others,  inflation, dark matter and dark energy. These were invoked solely to compete with observations, though, after dozens of years, they still serve as mathematical terms, with no whatsoever evidence for their existence. And as if that were not enough, several recent observational data appear to be in conflict with the model, which emphasizes the necessity to look for alternatives.\\
In a series of research articles, the unicentric model for the observable universe (UNIMOUN) was proposed, which turns out to be capable of
providing consistent answers to important open questions in cosmology. UNIMOUN is also mathematically and physically a sophisticated model, which is based on employing the new time-dependent H-metric to follow the spatial and temporal development of spacetime's topology.

Among others, UNIMOUN predicts that: 1) the observable universe was born in a flat environment,, 2) Our Big Bang was of measurable sizes and happened to occur in our neighborhood, 3) The energy density of matter is upper-bounded, 4) Big bangs are neither singular events nor invoked by external forces, but rather, they are common self-sustaining events in our infinitely large and flat parent universe, 5) The progenitors of BBs are created through the merger of cosmically dead neutron stars that tuned into DEOs, 6) The progenitors are made up of purely incompressible entropy-free gluon-quark superfluids, that are hidden from the outside world and decoupled from the spacetimes at the background
