inflation model

The inflation model in cosmology suggests that shortly after the Big Bang, the universe experienced an extremely rapid expansion—inflation—lasting a tiny fraction of a second. During this period, space itself expanded exponentially, smoothing out irregularities and explaining the universe’s large-scale uniformity. This rapid growth helps account for the observed uniform temperature and density, as well as the origin of tiny fluctuations that later formed galaxies. Essentially, inflation is a theoretical framework that describes how the universe expanded very quickly at its earliest moments, setting the stage for everything we see today.
