Abstract
The present status of the cosmology is briefly reviewed, specially paying attentions to new observational facts. In the first, the hierarchical structures of the nature is overlooked in relation to the fundamental forces between matters. This viewpoint is applied to the evolution of the universe based upon the big bang model as a history of bifurcations and materalizations of the forces. At the same time, the large-scale structures in the universe which are discovered in this decade are presented, and the structure formation scenario is shortly explained. It is shown that the, so called, dark matter problem is serious for understanding the formation of large-scale structures. Including these problems, the future expectations to observational cosmology are finally added.
