A basic task of modern cosmology is to understand the formation of the structure of the universe from the beginning to the present. One of the main ideas is the expansion of the universe, which can properly explain many of the features we observed, such as the flatness of the universe to the isotropy. Expansion creates an extremely homogeneous universe, but quantum fluctuations cause density differences in different places. These density differences are the beginning of the formation of the large-scale structure of the universe.
