Gravitational field theory
WebThe works of Isaac Newton and Albert Einstein dominate the development of gravitational theory. Newton’s classical theory of gravitational force held sway from his Principia, published in 1687, until Einstein’s work in the early 20th century. Newton’s theory is sufficient even today for all but the most precise applications. WebApr 11, 2024 · GWs, like electromagnetic waves (light), have a property called polarization which describes the geometry of the wave oscillations. GR predicts the existence of only two polarization modes for GWs: the tensor plus (+) and cross (×) modes (Figure 1). In GR, the two modes propagate independently from each other and move at the speed of light.

WebScalar–tensor theory. In theoretical physics, a scalar–tensor theory is a field theory that includes both a scalar field and a tensor field to represent a certain interaction. For example, the Brans–Dicke theory of gravitation uses both a scalar field and a tensor field to mediate the gravitational interaction .
