How does cosmic background radiation change the universe?

Answer 1

It doesn't

Astronomers search for an origin for radiation, especially microwave radiation, when it is discovered, but in large swaths of the universe, there is radiation that cannot be linked to any star, galaxy, or group of stars, leading them to believe that what we are hearing is the echo of a distant past. This radiation is known as the cosmic background.

Cosmic background radiation influences the universe by providing crucial evidence for the Big Bang theory. It helps us understand the early stages of the universe, its expansion, and the formation of structures like galaxies and clusters. Additionally, it contributes to the cosmic microwave background, which allows astronomers to study the universe's age, composition, and evolution.
