This may result in a deeper mystery and we are investigating. A high frequency gravitational wave generator including a gas filled shell with an outer shell surface, microwave emitters, sound generators, and acoustic vibration resonant gas-filled cavities. The outer shell surface is electrically charged and vibrated by the microwave emitters to generate a first electromagnetic field. The acoustic vibration resonant gas-filled cavities each have a cavity surface that can be electrically charged and vibrated by acoustic energy from the sound generators such that a second electromagnetic field is generated. The two acoustic vibration resonant gas-filled cavities are able to counter spin relative to each other to provide stability, and propagating gravitational field fluctuations are generated when the second electromagnetic field propagates through the first electromagnetic field.

On Feb. 11, 2016 the National Science Foundation publicly announced that the Laser Interferometry Gravitational Wave Observatory (LIGO) finally detected gravitational waves, thereby, showing that gravitational waves exist, further strengthening General Relativity (GR) theory predictions.
Gravitational waves can be seen as undulations in the structure of spacetime, or to be more exact, ripples in the curvature of the spacetime fabric. These waves are propagating fluctuations in gravitational fields, which arise due to the dynamics of massive physical entities. The source of gravitational waves may not be massive in nature, as long as its motion is represented by high frequency/high energy far from equilibrium dynamics. This can be observed from the energy-momentum tensor expression in the GR field equations.
Because of their physical nature (the graviton being a spin 2 particle), gravitational waves have the capability to penetrate solid matter at high frequency (HFGWs), moving at the speed of light. Furthermore, similar to electromagnetic waves, these gravitational waves (GWs) are carriers of energy and momentum. Moreover, GWs are transverse and quadrupolar in nature (stretching and squeezing space along their propagation path), and can be produced by accelerating asymmetric masses. The emission of high frequency gravitational waves denotes far-form-equilibrium phenomena.
Electromagnetic (EM) radiation (caused by accelerating electrically charged objects) when passed through a static magnetic field (of constant magnetic flux density) gives rise to gravitational waves at the same frequency as the EM radiation. This phenomenon is known as the Gertsenshtein Effect and can be utilized for a variety of applications ranging from advanced field propulsion (space drive), to communication through solid objects, as well as asteroid (planetoid) disruption and disintegration (when coupled with high energy electromagnetic field fluctuations).
In the language of quantum field theory, the Gertsenshtein Effect can be described as the mixing of a propagating photon with a graviton, via a Yukawa-type coupling mediated by a virtual photon from the background field.
