Abstract : Being the weakest of all known interactions, gravitation requires astronomical sized bodies for its study. Information concerning the nature of gravitation is obtained by studying the history of the universe, in particular, its age, rate of expansion, average mass density, composition and fragmentation. Also studied is the primeval black-body radiation, in particular its spectral distribution and isotropy. Gravitational effects are very intense in pulsars under study. The solar oblateness and quadrupole moment is related to a fundamental gravitational test. While much was learned in all these fields, a compelling test between the scalar-tensor theory and general relativity has not yet been found. (Author)
