===Introduction to Einsteinian universe===

The Einsteinian universe, or rather the Einsteinian General Relativity (EGR), as it should be more properly called, is a contemporary theory of universe. Basics of its gravitation have been explained in part 1 of this essay. Now, knowing how the ''apparent gravitational force'' has been generated let's look and the whole universe controlled by this apparent force.

The Einsteinian universe (EU), is a contemporary theory of universe. Basics of its gravitation have been explained in part 1 of this essay. Now, knowing how the ''apparent gravitational force'' has been generated let's look and the whole universe controlled by this apparent force.

First easy to notice feature is that in EGR the universe has been always approximately the same. It has been never changing, beyond trivial movements of celestial bodies. The EGR is described by the [[Perfect cosmological principle]].

The theory is called ''"Einsteinian"'' since it's Einsteinian type theory, except a bit deeper since it includes elements that Einstein didn't know about. For this reason there are also a few flaws which had to be dealt with and removed (as e.g. [[cosmological constant]]). The new elements and recognition of flaws showed up after 1985 when it turned out that the universe is not expanding (as it was obviosly neither expanding when Newton tried to describe it Without yet knowing though about the [[curvatures of spacetime]]. Yet almost purely Newtonian solution, with accuracy to

The EGR is explaning how the relativity of time and space (notions of non existence of absolute time and absolute space) are working in stationary, neither expanding nor contracting, eternal universe that has neither the beginning nor the end.  

The EU is explaning how the relativity of time and space (notions of non existence of absolute time and absolute space) are working in stationary, neither expanding nor contracting, eternal universe that has neither the beginning nor the end.  

The EGR which except explaining the mechanism of gravitational force as ''inertial force'' pushing masses towards their most probable positions of minimum energy in which it reveals its quantum nature, explains also why due to relativity of time in curved space the universe ''looks as if it were expanding'', and expansion were accelerating with

The EGR explains why the value of [[Hubble constant|Hubble "constant"]] <math>H(t)</math>, which in reality is an exponential function, since the redshift is in reality an exponential function of distance (or time, since <math>r=ct</math>, distance <math>r</math> is the same as time <math>t</math> multiplied by speed of light), so the redshift

''"[[Einstein's radius of universe]]"'' <math>R_E</math> in the above equation equals roughly 13 billion light years is implied by the above value of [[Hubble constant|Hubble "constant"]] and why it should be consistent with minimum of angular diameters of galaxies between redshifts Z=1 and Z=2 which is additional test of EGR.

Therefore the EGR explains most of numerical results that the [[Big Bang]] cosmology is unable to explain.

Therefore the EU explains most of numerical results that the [[Big Bang]] cosmology is unable to explain. EU is in fact an extension of Einstein's general realativity but it may not used be by this name because the [[realtivists]] jighjacked this name for their pseudo scientific hypothesis of the [[Big Bang]] which, when used, might have caused a confusion in some minds.
