Briefly describe how the cosmic microwave background was discovered. How does the existence and nature of this radiation support the Big Bang Theory? Noise from the Bell Labs antenna, after comparing notes, was determined to be the cosmic microwave background and the first strong evidence that the Big Bang had really happened. This discovery solved a long-standing problem, the origin of cosmic helium. The presence of helium and the abundance of it show it must have been present before the formation of the galaxies.
