Question and answer
How was CMB radiation first discovered?
The accidental discovery of cosmic microwave background radiation is a major development in modern physical cosmology. [ Although predicted by earlier theories, it was first found accidentally by Arno Penzias and Robert Woodrow Wilson as they experimented with the Holmdel Horn Antenna. The discovery was evidence for an expanding universe, (big bang theory) and was evidence against the steady
state model. In 1978, Penzias and Wilson were awarded the Nobel Prize for Physics for their joint discovery. ]

The most recent theory that upholds the big bang theory, but suggests a sudden expansion after the bang, is called the _____. User: What did scientists predict the big bang should have left? User: How was CMB radiation first discovered?
Weegy: How was CMB radiation first discovered? By the middle of the 20th century, cosmologists had developed two different theories to explain the creation of the universe. [ Some supported the steady-state theory, which states that the universe has always existed and will continue to survive without noticeable change. Others believed in the Big Bang theory, which states that the universe was created in a massive explosion-like event billions of years ago (later to be determined as 13.8 billion). The first published recognition of the cosmic microwave background (CMB) radiation as a detectable phenomenon appeared in a brief paper by Soviet astrophysicists A. G. Doroshkevich and Igor Novikov, entitled "Mean Density of Radiation in the Metagalaxy and Certain Problems in Relativistic Cosmology", in the spring of 1964. ] (More)
