   What is the earliest meaningful time after the Big Bang?

   • To explain the observed homogeneity of the universe, the duration in these models must be longer than 10 −32 seconds. Therefore, in inflationary cosmology, the earliest meaningful time "after the Big Bang" is the time of the end of inflation. After inflation ended, the universe continued to expand, but at a decelerating rate.
