The Einsteinian gravitation is a contemporary theory of stationary "Einstein's universe", explaning how the relativity of time and space (notions of non existence of absolute time and absolute space) is working in "Einstein's universe". The theory 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 , where is a change of Hubble constant with distance from observer converted to time , is Hubble "constant" near the Earth (at ).

The Einsteinian gravitation explains why the value of Hubble "constant" (which in reality is an exponential function), equal roughly implies density of space of universe as .

According to Einsteinian gravitation the Hubble constant , where c is speed of light in vacuum, and is "Einstein's radius of universe" equal roughly 13 billion light years as implied by the above value of Hubble "constant" should be consistent with minimum of angular diameters of galaxies between redshifts Z=1 and Z=2.

Also the Einsteinian gravitation, not allowing the expansion of universe, does not allow the Big Bang as a way of creation of the universe. It proves that the universe is stationary (with Newtonian arguments based on relativity of time, available to any intelligent high school student). Possibly for this reason it is not allowed to be published in scientific journals controlled by the scientific establishment.

Siince scientiffic journals don't want neither print nor even sent the desription of Einsteinian gravitation through peer review process I describe here in 11 steps how stationary "Einstein's universe" works:

Step 1. Assumptions

The basic assumption is that space of our universe is homogeneous and filed up with dust of galaxies with one galaxy corresponding to one dust particle (or a few, it makes no diff). Average density of this dust is (and this is impportant and that's why number of galaxies corresponding to one dust particle is not important). Additionally we assume that is what it usually is, is speed of light, is Newtonian gravitational constant. So the overall picture of our universe is rather simple. It is not expanding. No hidden tricks.
Now light starts radiating from some arbitrary "point zero" and photons start interacting wirh galaxies through "dynamical friction of photons" (the gravitational effect known in astronomy as "dynamical friction" but in this case acting on photons instead its usual action on heavier objects like stars). The gravitational energy of our "dust" gained through this dynamical friction contained in a ball of "dust" of radius around "point zero" is . This number is needed later to adjust the whole energy of "dust" to make the calculations exact (approximation is causing problems resulting as usually from approximations that all astrophysicists who wanted to make approximate calculations, including me, had, so I know that it has to be done exactly).
After photons of energy are radiated out from arbitrarily placed center of coordinate system called "point zero" (point with radial coordinate in homogeneous space making the space inhomogeneous and therefore the Newtonian "gravitational force" starts pushing the "dust" away from "point zero" this force is equal, from Newtonian equation for "gravitational force"
and
where is gravitational energy of "dust particle" (galaxy) gained from the action of light through the "dynamical friction of photons on this particular "dust particle" (really a galaxy, or a few) at distance from "point zero".
N.B. Usually astrophysicists neglect influence of a single photon on a Galaxy since it looks to them as "negligible". Though it is not exact but they think that no harm is done by small negligence of exactness of math. Apparently they are wrong as it is demonstrated below where exact calculations produce Hubble constant roughly as it is observed.
Explanations of the above equations:
The first one comes from the Newtonian force being and , the source of gravitational force being replaced by according to Einstein's physics. in this equation is diff of original mass of "dust" causing the "Newtonian attraction" adjusted by small causing a "repulsion" (acting in opposite direction than ). The rest is straight forward, but if not then ask.

Step 2: Integrating the mass of galaxies

... of spherical shell of radius of galaxies around "point zero" and thickness gives number
,
where is the mass of whole thin (of thickness ) shell of galaxies of radius and

Step 3. Calculating sum of all forcess acting on the shell

Substituting number from step 2 for the mass of galaxy resulting in
.
and
.
and so
.

Step 4. Integrating both sides of above equation

.
... over all spherical shells between "point zero" and to get total energy of "dust" absorbed from photons, and then differentiating both sides with respect to to get rid of integral on the right side of this equation, we get finally the starting where subscript now, as before, means "volume of universe of radius around point zero"
.

Step 5: Setting differential equation controlling the redshift

Substituting where is energy of photons at distance from their source and , number called in cosmology "curvature of space of Einstein's universe" (or "Einstein's radius of universe"), we get

Step 6: Solving the above equation

with initial conditions
and meanig selecting a solution that makes physicsl sense) one gets solution

Step 7: Slowing of proper time in deep space

Since in Einsteinian general relativity (EGR) there is nothing else but the time dilation and the curvature of space as the media controlling gravitation the EGR interpretation of the above result is that the time is running slower at a distance from (any) observer according to relation
,
where is proper time in deep space and is coordinate time at observer. The effect might be called "Hubble Time Dilation" (HTD) in honor of its discoverer, and as distinguished from the gravitational time dilation predicted by Einstein. It is the above equation that expresses the esential transition from Newtonian approach in which space and time are distinct, to general relativistic spacetime. It demonstrates also the essential relativity of time of Einsteinian theory.
Excelent agreement of the shown in step 11 acceleration of apparent expansion of this model universe with the value measured by the Supernova Cosmology Project team of astonomers lends strong additional support for this model.

Step 8. Flatness of spacetime

Differentiating the above equation at we get the relation between HTD in deep space and the curvature of space of Einstein's universe as
It suggests the existence of overlooked by cosmologists the antisymmetric part of Ricci tensor in time domain, named tentatively or Hubble Tensor (HT) such that , where is as before the (spatial) part of Ricci tensor, and is its anti symmetric (temporal) part, agreeing with the fact that conservation of energy (or 4-vectors in general, during their parallel transport) require the flatness of spacetime proposed already by Narlikar and Arp. It would explain also the flatnes of (stress-energy tensor) and the application of Noether Theorem in flat spacetime that implies conservation of all four components of stress-energy tensor as asserted by Feynman in 2nd volume of "Feynman lectures on physics".
So all the pieces of puzzle seem to fit the ancient "principle of conservation of energy". They contradict the speculations of authors of 1973 "Gravitation" by Misner, Thorne, and Wheeler who maintain that the spacetime is curved and that only the magnitude of stress-energy tensor is conserved (infamous Wheeler's "Momenergy"). The Einsteinian conclusion is still that the spacetime is intrinsically flat (as proven by elementary tensor calculus) and therefore the universe is not expanding and therefore it must be eternal, as once assumed by the Einsteinian gravitation and Carl Sagan.
But look at the further steps, even more interesting.

Step 9. Hubble redshift

It follows from results of steps 6 and 7 equivalently, that the redshift, produced by HTD, is equal to

Step 10. The same thing in form of Hubble "constant"

Such redshift simulates the expansion of space, with Hubble constant of this apparent expansion at equal
It is observed as about 70km/s/Mpc which implies that the radius of curvature of space of Einstein's model universe, is about 13Gly (13 billion light years). Very tough to measure but luckily very easy to calculate. And BTW, this value of implies the density of our universe about , which is about what is observed.

Step 11. Apparent accelerating expansion

After expanding Hubble "constant" into Taylor series around acceleration of this apparent expansion is approximately equal .
the above velue agrees within one standard deviation (maximum available accuracy for testind results of a theory) with 1998 observations by the Supernova Cosmology Project team of astronomers.
So the "accelerating expansion of our universe" blamed on mysteious "dark energy" for which cosmologists look since 1998 is just the Taylor term of expansion series of Hubble constant which is no constant but exponential function as shown in steps 6 or 7 (first as Newtonian result and second as Einsteinian interpretation of this Newtonian result). Cosmologists also call it "cosmological constant" (the "biggest blunder of Einstein's life") which can be shown not to exist at all. It might be eliminated from Einstein's field equation in rather straight forward manner. Though I couldn't show it Einstein for his approval since he was aready dead.
