Who was Thomas Gold? Information on American astronomer Thomas Gold biography, life story and works.
Thomas Gold; (1920 – June 22, 2004), American astronomer, who is best known as an originator of the steady-state theory of the universe. Gold was born in Vienna, Austria, on May 22, 1920. In the late 1930’s he went to England to attend Cambridge University. He taught astronomy there and then worked at Greenwich Observatory until 1956, when he went to the United States. (He later became a U.S. citizen.) After two years at Harvard, Gold went to Cornell University as chairman of its astronomy department and director of its Center for Radiophysics and Space Research.
In 1948, with Hermann Bondi, Gold proposed the steady-state theory, which embodies the so-called perfect cosmological principle: that the universe is statistically homogeneous at all times and places. To explain the observed expansion of the universe, the theory incorporated the notion that matter is continuously created. Opposition to the theory was bolstered by considerable observational evidence in the early 1960’s, and it has now been widely abandoned.
Gold’s later astronomical research dealt with various problems of planetary motion, with the nature and derivation of the lunar surface, with the nature of quasars, and with various aspects of relativity theory. He also worked on certain problems of geophysics and biophysics.
