Abstract

• It has been attempted to give a brief description of gravitational waves and its underlying physics for both theoretical and numerical aspects. First of all, the theoretical background of long sought gravitational waves (GWs) and its related connection to astrophysics and cosmology have been given in detail. Then, the accelerating charge, accelerating mass and amplitude of GWs are theoretically and numerically investigated within the framework of general relativity, classical mechanics and statistical mechanics points of view.
