Steady State Theory

subject fact

Steady State Theory is a kind of cosmology theory 2001-09-27 09:34:00.0
has definition Theory that the expanding universe was never in a state of appreciably higher density - i.e., that there was no "big bang" - and that matter is constantly being created out of empty space in order to maintain the cosmic matter density. has source: Ferris, T. 1988 Coming of Age in the Milky Way, Morrow, 2001-09-27 09:34:00.0
has definition A cosmological theory propounded by Bondi, Gold, and Hoyle in which the Universe has no beginning and no end and maintains the same mean density, in the face of its observed expansion, by the continuous creation of matter at the current rate of 2.8 × 10^-46 g cm^-3 s^-1 (or roughly one nucleon per cubic kilometer per year). Discovery of the microwave background has persuaded most astronomers to reject the steady-state theory. has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:34:00.0
