Quizplus · Accepted Answer

The presence of background radiation, also known as the cosmic microwave background, is considered one of the strongest pieces of evidence for the Big Bang theory. This radiation was predicted by the theory and was discovered in 1964. It is believed to be the residual energy left over from the early universe, about 380,000 years after the Big Bang, when the universe cooled enough for atoms to form and light to be able to travel through space. Its uniform distribution across the sky and its temperature distribution also support the idea that the universe was once in a highly compressed and hot state.
