The Friedmannian model of our observed Universe

TL;DR

This paper argues that the observed universe is best described by a specific Friedmannian model where Newtonian relations hold, suggesting a unique relativistic universe model consistent with observations.

Contribution

It identifies a unique Friedmannian universe model where Newtonian non-modified relations are valid, aligning theoretical models with observational data.

Findings

Only one Friedmannian model satisfies Newtonian relations in observations.

The universe's dynamics are consistent with this specific Friedmannian model.

Newtonian approximations are valid only in this particular relativistic universe model.

Abstract

According to observations, in our Universe for gravitational phenomena in a Newtonian approximation the Newtonian non-modified relations are valid. The Friedmann equations of universe dynamics describe infinite number of relativistic universe models in Newtonian approximation, but only in one of them the Newtonian non-modified relations are valid. From these facts it results that the Universe is described just by this only Friedmannian universe model with Newtonian non-modified relations.
