====Getting rid of cosmological constant====

First idea that came to my mind was that if the Einstein's value of [[cosmological constant]] stabilizes the universe then one should come up with such a constant that changes together with <math>R</math> (contraction of Ricci tensor) in such way that their sum vanishes. I called this hypothetical constant "contraction of ''[[Hubble tensor]]''" in honor of discoverer of [[Hubble redshift]]. To have a contraction one needs also a tensor itself so I needed a ''[[Hubble tensor]]'' as well. It would be a tensor having such properties that its contraction multiplied by half of metric would be equal exactly <math>\Lambda_E</math> (Einstein's value of [[cosmological constant]]). I just learned lately from a mathematician in my school, that such arangement is possible if the metric is non symmetric. Which it is, since it was metric required by Einstein for the spacetime <ref>Einstein, A., ''"On the Theory of Generalized Gravitation"'', April 1950 issue of ''"Scientific American"''. Einstein's paper has been dropped from the bibliography of Einstein's papers in 1973 ''"Gravitation"'' by Misner, Thorne, and Wheeler.</ref>.
