Geodetic precession horndeski

WebThe geodesic precession depends on the metric and appears even in a particle following geodesic motion. The Thomas precession depends on the particle's absolute acceleration and thus vanishes for a particle in geodesic motion. The geodetic effect (also known as geodetic precession, de Sitter precession or de Sitter effect) represents the effect of the curvature of spacetime, predicted by general relativity, on a vector carried along with an orbiting body. For example, the vector could be the angular momentum of a gyroscope orbiting the Earth, as carried out by the Gravity Probe B experiment. The geodetic effect was first predicted by Willem de Sitter in 1916, who provided relativistic corrections to the Earth–…
