August 24, 2000   Using the Rossi X-Ray-Observing Satellite, scientists have detected rapid oscillations in the X-ray emissions from three neutron stars. In order to explain these oscillations, theorists are asserting that they may be caused by what is called "frame dragging." This is where the gravitation field of a black hole or neutron star is so intense that it drags space and time along with it, as the object rotates. [Frame dragging would occur over and above the ordinary curvature of space-time that intense gravitational fields are known to produce.]  Article.
