Brans-Dicke Theory

Definition

Astronomy

  • A theory which attempts to explain effects (like the bending of light in gravitational fields) which are normally regarded as relativistic without reference to relativity. Proposed in the late 1960s by scientists at Princeton University, it essentially relies upon new notions about gravitation, with a varying gravitational constant, to explain effects usually ascribed to relativity. If true, the theory involves a steady decrease in gravitation as the universe has expanded.
