Question

Quizplus · Accepted Answer

The Cosmic Microwave Background (CMB) radiation, which is a background "glow" of microwaves with a blackbody temperature of about 3 K, is considered strong evidence for the Big Bang theory. It is the afterglow radiation from the hot, early universe, now cooled and stretched to microwave wavelengths due to the expansion of the universe.
