Quizplus · Accepted Answer

Inflation is believed to have occurred when the universe was less than 10^-33 seconds old, during which the universe underwent an extremely rapid expansion by a factor of approximately 10^30. This expansion was driven by a change in the average energy of the vacuum of spacetime, known as the inflationary field. Therefore, all of the above options are correct.
