Definition: cosmology from Philip's Encyclopedia

Branch of scientific study that brings together astronomy, mathematics and physics in an effort to understand the make-up and evolution of the universe. Once considered the province of theologians and philosophers, it is now an all-embracing science, which has made great strides in the 20th century. The discovery by Edwin Hubble in the 1920s that galaxies are receding from each other promoted the Big Bang theory. Associated with this is the oscillating universe theory. The other main theory is the steady-state theory.


cosmology

From The Columbia Encyclopedia
area of science that aims at a comprehensive theory of the structure and evolution of the entire physical universe . Present models of the universe hold two fundamental premises: the cosmological principle and the dominant role of gravitation . Derived by Hubble, the cosmological principle holds that if a large enough sample of galaxies is considered, the universe looks the same from all positions and in all directions in space. The second point of agreement is that gravitation (or an antigravitation force, called dark energy ) is the most important force in shaping the universe. According to Einstein's general theory of relativity , which is a geometric interpretation of gravitation, matter produces gravitational effects by actually distorting the space about it; the curvature of space is described by a form of non-Euclidean geometry . A number of cosmological theories satisfy both the cosmological principle and general relativity. The two main theories are the big-bang hypothesis and…
