Po etomu povodu pochitaite populyarnuyu stat'yu I. Karachenceva i A.Chernina v zhurnale "V mire nauki" http://www.sciam.ru/2006/11/cosmology.shtml - eto ya Vam posovetoval 2 mesyaca nazad. Togda Vy, pohozhe, delali men'she orfograficheskih oshibok. V stat'e est' grafik zavisimosti skorostei otnositel'nogo dvizheniya neskol'kih desyatkov blizhaishih galaktik ot rasstoyaniya do nih. Iz etogo grafika vidno, chto samye blizkie galaktiki primerno s ravnoi veroyatnost'yu kak udalyayutsya, tak i priblizhayutsya. Delo v tom, chto oni gravitacionno svyazany i dvigayutsya po slozhnym traektoriyam v sostave Mestnoi gruppy galaktik. No nachinaya s kakogo-to rasstoyaniya kak budto vklyuchaetsya sila ottalkivaniya - galaktiki udalyayutsya tem bystree, chem oni dal'she, prichem koeficient proporcional'nosti sootvetstvuet postoyannoi Habbla. Avtory nazyvayut eto yavlenie mestnym habblovskim potokom i schitayut, chto eto pryamo ukazyvaet na nalichie sily ottalkivaniya, svyazannoi s tak nazyvaemoi temnoi energiei pryamo zdes', v Mestnoi gruppe galaktik, libo v neposredstvennoi blizosti ot nee.
