This paper is a little upgrade of the sections 5 “Cosmology|” and 6 “Conclusion” in the paper “The informational physical model: some fundamental problems in physics”, vixra.org/pdf/2007.0001v3, whilst the whole replacement of this paper seems would not be rational, in one, though rather probably essential, point – in this case rather possibly useful cosmological experiment is proposed. The experiment follows from the fact that “escape velocity” for a concrete body doesn’t limit some borders for moving in the “body’s atmosphere” other bodies. For example, the Erath escape velocity is 11.19 km/s, however bodies with different velocities can move apart Earth on any distance, if a velocity is →11.19 km/s – up to infinity, before stopping and return back to Earth. Correspondingly, though SMBH have two borders, i.e. real one, i.e. the size of the compact extremely dense central object, and “virtual” one, i.e. the GR “event horizon”, the real SMBH “atmosphere”, which feeds on accretion of external matter, spreads outside both borders, including, rather probably, it take part in composing of the SMBH jets. In this paper the sections numbers, and the references that are in the host paper, are mostly conserved.
