Question

How does weak background radiation coming from every direction in the sky support the Big Bang Theory? (2 points)
• it provides evidence of universe expansion
• it provides evidence of the universe's decreasing mass
• it provides evidence of universe contraction
• it provides evidence of the universe's increasing mass

Answer 1

The correct point that supports the Big Bang Theory in relation to weak background radiation is:

• it provides evidence of universe expansion

This weak background radiation, known as the Cosmic Microwave Background (CMB) radiation, is considered a remnant of the early universe and supports the idea that the universe has been expanding since the Big Bang.
