Explanation: Dark energy is a theoretical form of energy that is thought to exist in empty space and is responsible for the observed accelerated expansion of the universe. According to the theory of the Big Bang, the universe began as an extremely hot and dense state about 13.8 billion years ago. Initially, the expansion of the universe was slowing down due to the gravitational pull of matter. However, about 5 billion years ago, scientists discovered that the expansion was actually accelerating, defying the expectations of traditional gravitational theories. To explain this unexpected acceleration, scientists proposed the existence of dark energy, which counteracts the gravitational pull and causes the expansion of the universe to accelerate.
