Brans–Dicke theory

Physics

A modification of the general theory of relativity that combined tensor and scalar qualities and allowed the gravitational constant G to vary with time in a way that is in accord with Mach’s principle. The Brans–Dicke theory was proposed by the American physicists Carl Brans (1935– ) and Robert Dicke (1916–97) in 1961. This type of theory has largely been abandoned since its predictions have not been supported by accurate experimental tests of the general theory of relativity. The Brans–Dicke theory is closely related to some types of unified-field theory.

Astronomy

An alternative to Einstein’s theory of general relativity which attempts to incorporate Mach’s principle. Among other things, this theory predicts that the value of Newton’s gravitational constant, G, should change with time. It was originated by the American physicists Carl Henry Brans (1935– ) and R. H. Dicke.
