   A fluctuation in spacetime caused by accelerating mass, which propagates as a wave at the speed of light.

   • It is therefore apparent that the existence of gravitational waves can be deduced from general relativity just as the existence of electromagnetic waves can be deduced from Maxwell's theory.
   • It might be anticipated that a pulsating star, such as a Cepheid is believed to be, would emit gravitational waves abundantly; but when the question is examined analytically, this expectation is not confirmed.
   • Fourth, there exists a strong competition on the side of purely astronomical means for indirect detection of gravitational waves.

   A gravity wave.

   • It is difficult to see whether a sufficient amount of energy is communicated to the sea by the air masses directly in the form of compressional waves or it is transmitted or increased by the action of gravitational waves.
   • In the used model sound waves and external gravitational waves have been filtered; combined inertial-internal gravitational waves, however, are still included in the equations.
