The inflationary epoch is the most widely accepted solution to both the horizon and flatness problems. It posits that the universe underwent a brief period of exponential expansion in the very early stages of its existence, smoothing out any irregularities and making it appear flat and homogeneous on a large scale. The inflationary epoch is the most widely accepted explanation for the horizon and flatness problems in cosmology. It proposes that the universe underwent an exponential expansion in the first fraction of a second after the Big Bang, causing the universe to become extremely flat and uniform in temperature. This explains why regions of the universe that are now far apart appear to have the same temperature and properties, even though they could not have interacted since the beginning of the universe.
