Question

Quizplus · Accepted Answer

Inflation refers to a sudden and rapid expansion of the universe, which is believed to be driven by the energy released when the strong and electroweak forces froze out from the Grand Unified Theory (GUT) force. This theory is believed to explain a number of observations that cannot be explained by standard cosmology, such as the uniformity of the cosmic microwave background radiation and the large-scale structure of the universe.
