The model of a flat (Euclidean) expansive homogeneous and isotropic relativistic universe in the light of the general relativity, quantum mechanics, and observations

TL;DR

This paper develops a comprehensive model of a flat, homogeneous, and isotropic relativistic universe that aligns with general relativity, quantum mechanics, and observational data, providing a unified theoretical framework.

Contribution

It presents a unified model of the universe consistent with general relativity, quantum mechanics, and observations, emphasizing the flat, homogeneous, and isotropic nature.

Findings

Model aligns with Einstein's general relativity

Consistent with quantum mechanics and observations

Supports a flat, homogeneous, isotropic universe

Abstract

Assuming that the relativistic universe is homogeneous and isotropic, we can unambiguously determine its model and physical properties, which correspond with the Einstein general theory of relativity (and with its two special partial solutions: Einstein special theory of relativity and Newton gravitation theory), quantum mechanics, and observations, too.
