They are caused when two massive objects, for example neutron stars, are orbiting closely around each other with an incredible speed. . In 1918 Einstein published the paper ÜBER GRAVITATIONSWELLEN [1] in which, for the first time, the effect of gravitational waves was calculated, resulting in his famous “quadrupole formula” (QF). Einstein was forced to this publication due to a serious error in his 1916 paper [2], where he had developed the linear approximation (“weak- field”) scheme to solve the field equations of general relativity (GR). In analogy to electrodynamics, where accelerated charges emit electromagnetic waves, the linearized theory creates gravitational waves, popagating with the speed of light in the (background) Minkowski space-time. A major difference: Instead of a dipole moment, now a quadrupole moment is needed. Thus sources of gravitational waves are objects like a “rotating dumbbell”, e. g. realized by a binary star system. some history. (based on D. . Kennefick’s. work). Historical tidbits. 1776: Laplace suggests four mechanisms that could explain secular perturbations of Moon-Earth orbit. One the explanations was a non-instantaneous propagation of gravity, affecting the binary system (abandoned because its speed would be too large to be measurable to explain the effect). .
