Question

Quizplus · Accepted Answer

During the GUT era, the strong and electroweak forces were unified into a single force. As the universe expanded and cooled, the force split into two separate forces, releasing an enormous amount of energy. This energy caused the universe to undergo a period of rapid expansion, known as inflation, which resulted in a temporary increase in the rate of inflation.
