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 sugests that the universe is stationary (with Newtonian arguments based on relativity of time, which any intelligent high school student should easily comprehend).

==Einsteinian gravitation==
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) are working in stationary (neither expanding nor contracting) ''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 <math>dH/dt=-H_o^2/2</math>, where <math>dH/dt</math> is a change of [[Hubble constant]] with distance from observer converted to time <math>t</math>, <math>H_o</math> is [[Hubble constant|Hubble "constant"]] near the Earth (at <math>t=0</math>).
The Einsteinian gravitation explains why the value of [[Hubble constant|Hubble "constant"]] <math>H(t)</math> (which in reality is an exponential function), <math>H_o</math> equal roughly <math>70km/s/Mpc</math> implies density of space of universe as <math>6\times 10^{-27}kg/m^3</math>.
According to Einsteinian gravitation the [[Hubble constant]] <math>H_o=c/R_E</math>, where c is speed of light in vacuum, and <math>R_E</math> is ''"[[Einstein's radius of universe]]"'' equal roughly 13 billion light years as implied by the above value of [[Hubble constant|Hubble "constant"]] should be consistent with minimum of angular diameters of galaxies between redshifts Z=1 and Z=2.
