Quizplus · Accepted Answer

The cosmic background radiation is believed to be uniformly distributed throughout the entire universe, which means it should be equally bright in all parts of the sky. This is because the radiation was emitted early in the universe's history, and has been traveling through space for roughly 13.8 billion years. As a result, it should be present in all directions, though it may appear slightly brighter or fainter in certain regions due to slight variations in temperature.
