The result turned out to be <math>\Delta H_o= \sqrt{4 \pi G \rho}</math>, where <math>G</math> is Newtonian gravitational constant, and <math>\rho</math> is the mass density of universe <ref>See step-by-step calculations in [[Einsteinian gravitation]]</ref> but also that it is the whole [[Hubble constant]] of our universe. There was nothing left for the expansion of space.

It means that the cosmological [[redshift]] might be the result of interaction of photons with the masses of universe due to [[dynamical friction]] and none due to the expansion of space. Necessary conclusion was that the space of our universe is not expanding and the redshift is due [[dynamical friction]] of photons only (as Fritz Zwicky once suspected, just couldn't prove it with his math).
