The evidence of cosmic microwave background radiation supports the Big Bang theory.

Microwave (Cosmic background radiation).
cosmic microwave background radiation
The radiation left over from the big bang is found in the microwave region of the electromagnetic spectrum. As the universe expanded and cooled, the intense hard gamma radiation that existed became radio waves in the low gigahertz region, characteristic of a temperature around 30 Kelvin.
The redshift of the cosmic microwave background radiation
Among other things, it means Cosmic Microwave Background.
Olbers' paradox is resolved in the context of the expanding universe and the presence of cosmic microwave background radiation by understanding that the universe is not infinite in age or size. The expansion of the universe causes light from distant stars to redshift, making them fainter and cooler, and the cosmic microwave background radiation fills the universe with a uniform glow, accounting for the darkness of the night sky.
