The correct answer is: It provides evidence of universe expansion.
Explanation:
The weak background radiation that is coming from every direction in the sky is known as the Cosmic Microwave Background (CMB). This radiation is a remnant from the early stages of the universe, around 380,000 years after the Big Bang.
The presence of the CMB supports the Big Bang Theory because it is consistent with the hypothesis that the universe was once in a hot, dense state and has been expanding ever since. The CMB is essentially the remnants of the intense heat and energy from the early universe, which has cooled down over time.
The uniformity and isotropy (same in all directions) of the CMB provide strong evidence for the expansion of the universe. According to the Big Bang Theory, as the universe expanded, the radiation likewise expanded and cooled, resulting in the current state of the CMB.
Multiple observations and measurements of the CMB, including its temperature and distribution across the sky, have been made by various space-based and ground-based experiments. These observations have consistently supported the idea that the universe is expanding, confirming the predictions of the Big Bang Theory.
To get this answer, you would need to understand the concept of the Cosmic Microwave Background and its connection to the Big Bang Theory. You would also need to be familiar with the observational evidence and measurements that support the expansion of the universe.
