Quizplus · Accepted Answer

Inflation refers to a theory in cosmology where the universe experienced an exponential expansion right after the Big Bang, specifically after the separation of the strong force from the grand unified force (GUT force). This period of rapid expansion is thought to have occurred within the first fractions of a second after the universe's inception.
