Edited sentence: In 1985 one W.It has to wait until discovered by someone with access to scientific publications or at least to arXiv.It turned out that the assumption of strict conservation of energy results in the necessity of existence of a tensor of generalized time dilation equal to minus tensor of curvature of space.Jim 08:39, 24 August 2007 (UTC).Jim Jastrzebski noticed that an assumption of strict conservation of energy forces Einstein's theory of gravitation to admit the tired light as the time running slower at a greater distance from an obsever (for any observer, which turns out not to cause any ligical contradiction).The results, except explaining the tired light as a feature of the metric of stationary spacetime and therefore also explaining the Hubble redshift in a stationary space with predicted Hubble constant being equal , where  is speed of light and  is Einstein's radius of the Universe (ca.Unfortunately this small extension of Einstein's theory contradicts the non conservation of energy resulting from the Big Bang hypothesis so it was not allowed to be published in any scientific journal so for this reason it can't be published in Wikipedia neither.for our universe), explains also the illusion of accelerating expansion of space with the predicted acceleration of expansion  while presently (2007) the observed value is  (and so well within one standard deviation from the value predicted by Einstein's theory with strict conservation of energy)
