Sentences with phrase «microwave background»
The phrase "microwave background" refers to a faint glow of microwaves present throughout the entire universe. It is leftover energy from the early stages of the universe, when it was extremely hot and dense. This glow helps scientists study the history and structure of the universe. Full definition
