The so far biggest simulation of the growing of cosmic structures and the development of galaxies, quasars and black holes was published by the Virgo-Consortium, an international group of astrophysicists, in Nature in June 2005. This "millenium simulation" uses more than ten billions of notional particles. Each of them represents the mass of about one billion of suns, thus showing the development of the distribution of matter in a cubic region of the universe with a length of the edges of more than two billions of light-years. With the new simulation the astrophysicists can reconstruct the developmental history of about 20 millions of galaxies and the genesis of superheavy black holes which sometimes in their cores flash up as quasars.
