Levi Anderson

The inflationary period in cosmology refers to a rapid expansion of the universe believed to have occurred in the early moments after the Big Bang. This period is theorized to have lasted for an extremely short duration, during which the universe expanded exponentially, stretching out spacetime and smoothing out any irregularities. It is thought to have played a crucial role in explaining the large-scale structure and uniformity of the universe observed today.
