Chronology of the universe - Wikipedia
WEBIn non-traditional versions of Big Bang theory (known as "inflationary" models), inflation ended at a temperature corresponding to roughly 10 −32 seconds after the Big Bang, but this does not imply that the inflationary era lasted less than 10 −32 seconds.

WEBFeb 21, 2024 · The Inflation Theory proposes a period of extremely rapid (exponential) expansion of the universe during its first few moments. It was developed around 1980 to explain several puzzles with the standard Big Bang theory, in which the universe expands relatively gradually throughout its history.
