A Critique of the relativistic cosmology

TL;DR

This paper critically examines relativistic cosmological models, questioning the assumption of expanding 3-space and highlighting the lack of observational evidence, which could undermine the foundational geometry of these models.

Contribution

It challenges the prevailing view of an expanding 3-space in relativistic cosmology, proposing that this assumption may be unfounded and based on potentially flawed theoretical foundations.

Findings

No observational evidence for 3-space expansion

Questioning the validity of Riemannian geometry in cosmology

Potential flaws in the foundation of relativistic models

Abstract

All the relativistic cosmological models of the universe, except Einstein's static model, imply that the 3-space of the spacetime of the universe is also expanding apart from the matter and the radiation in it. However, there is no observational evidence of the expansion of the 3-space of the spacetime of the universe. Actually, the 3-space of the spacetime of the universe might not be expanding at all. Consequently, the conceptual foundation of the relativistic cosmological models of the universe based on the general theory of relativity, which in turn is based on Riemannian geometry, might be faulty and misleading.
