... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...

... Future seminars . ... The History of our Universe and its Physics ". ... In our astronomical environment everything appears to age and decay; even the proton may have a limited half-life. The decay products of all the universes expand eventually into the inter-universal medium (IUM), and that causes the new universes to start uniformly, with small variations due to the local distribution of galaxy clustering. ... universe stayed cool enough so that the galaxy characteristics were not melted away. ...
