One result of this theory was tested in the 2004 GP-B experiment, which tentatively confirmed the geodetic effect. The equations that govern this theory equate curvature with energy and momentum, represented by the stress-energy tensor. This theory predicts that objects close to a rotating mass undergo precession, a phenomenon known as frame-dragging. It also predicts a phenomenon whereby light is bent by massive objects, called gravitational lensing. For 10 points, name this theory, which is governed by Einstein's field equations, and has a "special" counterpart.
