It motivates the inclusion of rotational degrees of freedom in the Einstein\u2013Cartan gravity, representing the minimal and the most natural extension of the General Relativity. One can, consequently, expect the violation of the cosmic isotropy by the rotating Universe. We study chirality of the vorticity of the Universe within the Einstein\u2013Cartan cosmology. The role of the spin of fermion species during the evolution of the Universe is studied by averaged spin densities and Einstein\u2013Cartan equations. It is shown that spin density of the light Majorana neutrinos acts as a seed for vorticity at early stages of the evolution of the Universe. Its chirality can be evaluated in the vicinity of the spacelike infinity. It turns out that vorticity of the Universe has right-handed chirality.<\/jats:p>","DOI":"10.3390\/e14050958","type":"journal-article","created":{"date-parts":[[2012,5,16]],"date-time":"2012-05-16T12:25:29Z","timestamp":1337171129000},"page":"958-965","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["On Chirality of the Vorticity of the Universe"],"prefix":"10.3390","volume":"14","author":[{"given":"Davor","family":"Palle","sequence":"first","affiliation":[{"name":"Division of Theoretical Physics, Rugjer Bo\u0161kovic Institute, Bijenicka cesta 54, P.O.B. 180, HR-10002 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2012,5,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1535","DOI":"10.1007\/BF02778238","article-title":"On the broken gauge, conformal and discrete symmetries in particle physics","volume":"109","author":"Palle","year":"1996","journal-title":"Nuovo Cimento A"},{"key":"ref_2","first-page":"445","article-title":"On the lifetime of a cold dark matter particle and the cosmological diffuse photon background","volume":"115","author":"Palle","year":"2000","journal-title":"Nuovo Cimento B"},{"key":"ref_3","first-page":"747","article-title":"On heavy Majorana neutrinos as a source of the highest energy cosmic rays","volume":"118","author":"Palle","year":"2003","journal-title":"Nuovo Cimento B"},{"key":"ref_4","first-page":"87","article-title":"On the enhancement of the QCD running coupling in the noncontractible space and anomalous Tevatron and HERA data","volume":"24","author":"Palle","year":"2001","journal-title":"Hadronic J."},{"key":"ref_5","first-page":"469","article-title":"On the quantum loop weak interaction corrections at high energies","volume":"24","author":"Palle","year":"2001","journal-title":"Hadronic J."},{"key":"ref_6","unstructured":"Palle, D.
