Rev. Lett.) On. .</ P> <P> rotation because all stars are in the shape of the ball will not be strict, and hence can not be described by the theory of spherically symmetric. .In 1963, New Zealand physicist Roy Kerr was able to describe the uncharged rotating star solution of Einstein's gravitational field equation, the significance of this theory in astronomy, as much as the discovery of a new elementary particles, because .His name, by such stars collapse to form black holes called Kerr black hole. .</ P> <P> Kerr black hole with constant speed of rotation, according to Einstein's gravitational field equation, a rotating black hole regulation shrunk to the gravitational field of stars will eventually reach a state of equilibrium, this state depends only on two parameters .that the mass and angular momentum, the latter representing the speed of rotation of the star, similar to the spin of elementary particles. .</ P> <P> has been such a black hole with angular momentum, known as one of nature's most perfect body, and its conservation laws associated with the theoretical hypothesis is still in use for 40 years after the mysterious. .Now simulation figure shows: the first is axisymmetric Kerr black hole, that is rotating around the axis of symmetry, for the geodesic motion of test particle whose energy is conserved; while its angular momentum around the axis of symmetry is also conserved quantity; addition also allows testing of its .follow the law of conservation of the third particle; in Kerr black hole, all the mathematical equation, including disposing of some of the gravitational wave equation, can be separation of variables, which are clearly the solution. .</ P> <P> researchers may, by the image analysis, in the Kerr black hole environment, according to general relativity to describe how a small black hole to rotate around a massive black hole action. .Meanwhile, although the image from the establishment by the theoretical model, but the researchers hope, also the results of visualization of the theory of gravitational wave astronomy has played the role, or amendments or additions. .</ P> </ p>.
