Cosmic Microwave Background Radiation Anisotropies: Their Discovery and Utilization

George Smoot held his Nobel Lecture December 8, 2006, at Aula Magna, Stockholm University. He was presented by Professor Per Carlson, Chairman of the Nobel Committee for Physics.

Summary: A detailed account is given of the search for anisotropies in the cosmic microwave background radiation. The COBE satellite, launched in 1989, found very small differences between the temperatures of the cosmic microwave background radiation in different directions. Small fluctuations, of the order of parts per million, were found. These are expected to make up the seed for the formation of structures in the galaxy, giving strong support for the Big Bang theory.
