Answer 1

The weak background radiation coming from every direction in the sky supports the Big Bang Theory by providing evidence of universe expansion. This radiation is known as the Cosmic Microwave Background (CMB) and is considered a remnant of the hot, dense state of the early universe. Its uniformity and presence throughout the cosmos indicate that the universe has been expanding since the Big Bang.

So, the correct response is: It provides evidence of universe expansion.
