What is the cosmic microwave background?
Any atoms present at that time were quickly broken apart into small particles . The radiation from the CMB in photons was scattered off the electrons."Thus, photons wandered through the early universe, just as optical light wanders through a dense fog," NASA wrote.
Robert Wilson discovered the cosmic microwave background radiation in 1964 along with Arno Penzias, putting the Big Bang theory on solid footing. Wilson and Penzias won the 1978 Nobel Prize in physics for the find. American cosmologist Ralph Apher first predicted the CMB in 1948, when he was doing work with Robert Herman and George Gamow, according to NASA.
Both teams quickly published papers in the Astrophysical Journal in 1965, with Penzias and Wilson talking about what they saw, and Dicke's team explaining what it means in the context of the universe. .The CMB is useful to scientists because it helps us learn how the early universe was formed. It is at a uniform temperature with only small fluctuations visible with precise telescopes.
