The theory of inflation was developed to resolve the horizon problem, which states that regions of the universe that are too far apart to have ever been in contact with each other appear to have the same temperature and composition. The theory proposes that the universe underwent a rapid expansion, or inflation, in the first fraction of a second, allowing these regions to come into contact and become homogeneous. The theory of inflation was developed to resolve a conflict between observation and theory regarding the uniformity of the cosmic microwave background radiation. The theory proposes that the early universe underwent a period of extremely rapid expansion, causing the universe to become homogeneous and isotropic on large scales.
