The Introduction of Research Work Dr. George Smoot and the Big Bang Theory

     Cosmic Background Explorer; COBE) was the heat radiation left over from the "big bang," and it has the same features as the blackbody radiation. According to the speculation of big bang theory, the temperature was about 3000 degrees when universe began to release and emit rays. With the expansion of the universe, the background radiation was gradually cooled, but the original shape of blackbody radiation spectrum will be retained. This means that if we can detect these remaining radiation billions of years ago, it will be key evidence of the Big Bang theory. But detecting those weak radiation signals from distant space and past to Earth is extremely difficult.

     American NASA decided to start the research projects related to cosmology in 1970, and among the numerous proposals, Dr. Smoot became a person in charge of "the measure of tiny temperature fluctuations in the microwave background radiation" as a result of his strong science background as well as expertise for cutting-edge physics. Dr. Smoot hoped to find "time wrinkles", and "cosmic seed," through this research. However, he won the Nobel Prize by the participation in the plan.
