This page is the introduction to the section on the large scale structure of the universe in which we live. Clusters and superclusters of galaxies including the largest structures known today. As the fluctuations grow in their amplitude, the evolution becomes too complex and theorists have to use computers to follow the subsequent evolution. The early evolution, when the seed fluctuations are small, can be calculated analitycally on a piece of paper without the help of large supercomputers. The nearby universe then shows a large amount of structure on the very largest scales.

The idea of whether galaxies are distributed uniformly in space can be traced to edwin hubble, who used his catalog of 400 extragalactic nebulae to test the homogeneity of the universe hubble 1926, finding it to be generally uniform on large scales.

The plot shows a thin slice through the universe the pie shapes containing nearly 10,000 galaxies. At about 10,000 years after the big bang, the temperature had fallen to such an extent that the energy density of the universe began to be dominated by massive particles, rather than the light and other radiation which had predominated earlier.

Peebles argues that the evolution proceeded from a nearly uniform initial state to a progressively more irregular and clumpy universe.
Introduction to large scale structure of the universe. But these researchers were not convinced the approach would work. He starts with homogeneous isotropic models of the universe and then, by considering perturbations, he leads us to modern cosmological theories of the large. On large scales the universe displays coherent structure, with galaxies residing in groups and clusters on scales of mpch, which lie at the intersections of long filaments of galaxies that are 10 mpch in length.
