structure formation

The formation of large-scale structure such as galaxies, clusters of galaxies, etc. in the Universe. Most theories of structure formation are based on the Jeans instability in the context of general relativity theory, with the large-scale structure emerging from the inhomogeneity of matter in the Universe. It is thought that quantum fluctuations in the early Universe were responsible for the necessary inhomogeneities, with inflation expanding these fluctuations. Evidence that this theory is correct comes from the small variations in the cosmic microwave background radiation found by COBE. At present none of the detailed quantitative theories of structure formation can be regarded as definitive. One of the difficulties is that the nature of dark matter is not known.
