By Abraham Zelmanov, D. Rabounski, S. Crothers, L. Borissova
This e-book was once written in 1944 through Abraham Zelmanov, a favourite scientist operating more often than not relativity and cosmology. Herein he constructs the speculation of actual observable amounts in most cases Relativity (Chronometric Invariants), and applies it to figure out all attainable cosmological types in the framework of Einstein conception situations of evolution which may be theoretically possible for a very inhomogeneous and anisotropic Universe.

This is a “liquid”, or better, a “gas”, where galaxies are “molecules”. ‡ Both kinds of the accompanying coordinates are the same in a homogeneous universe. Chapter 1 Preliminary Notices 46 thus we obtain, finally T0i = T0i r . 4) The way to build the theory of an inhomogeneous universe To retain considerations on the Universe as a whole from the beginning of the study. To split the study into the following stages. 1. Consider the evolution of an element of an inhomogeneous anisotropic universe.
On the contrary, by the falsity of Supposition C, Shapley proposed [45, 46] his explanation of the difference, having a basis in observational data. ¨ numerical values of ρ, R , k2 , and Λ used by McVittie had been obtained R R in [39, 40], the bounds of T had been found by him in [41, 42], where he used an intermediate method to calculate other values. Therefore the method McVittie followed is logically contradictory. 15 Chapter 1 Preliminary Notices Non-uniformity of the visible part of the Universe The Harvard studies (Shapley and others) differ from the studies made at the Mount Wilson observatory (Hubble and others).
The Friedmann case in the theory of a homogeneous universe is inapplicable to thermodynamics. At the same time, this case is sufficient for dynamics and observational tests of the theory, and is that sole case which is applicable for comparing the theory with Classical Mechanics in strong form. Taking these as a basis for building the theory of an inhomogeneous universe, we can say that the Friedmann case cannot be applicable to thermodynamics; it is ∗ The mean curvature gradient in explicit form cannot appear in the cosmological equations, because it must include the third derivatives of components of the metric tensor.
