Alternatives to it include BransÂ–Dicke theory, which adds an extra scalar field.
One test of this theory involved measuring the periastron time of the Hulse-Taylor binary pulsar, and another used gyroscopes to measure the geodetic drift rate. Alternatives to it include BransÂ–Dicke theory, which adds an extra scalar field. Theodor Kaluza added an extra spatial dimension to this theory, which is built upon ten coupled hyperbolic and elliptic partial differential equations. In addition to frame-dragging, this theory correctly predicted that the presence of matter curves space-time. A principle central to this theory is the equivalence of gravitational and inertial mass. For 10 points, name this theory formulated by Einstein that expanded upon special relativity.
