Some Problems About The Gravitational Wave

Authors: Ting-Hang Pei

The contribution of the dipole moment in the generation of the gravitational waves is reconsidered here whether it is useful or not. In this article, we find that the contribution of the dipole moment is nonzero. The gravitational wave is responsible for delivering the information of the spacetime structure and gravitational field from the source. Since the general relativity predicts the speed of gravity at most as fast as the speed of light, the change of gravity is not instantaneous and two cosmic objects must produce the gravitational waves to realize the gravitational attraction. The phenomenon that the gravitational wave cannot escape makes the black hole like an isolated system and it results in such black hole losing ability to attract other massive bodies. Therefore, we also discuss the possibility of the gravitational waves escaping the black hole.
