"Gravitational waves are 'ripples' in space-time caused by some of the most violent and energetic processes in the Universe."

"A gravitational wave is an invisible (yet incredibly fast) ripple in space. Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by."

"Gravitational waves are distortions in the fabric of space and time caused by the movement of massive objects, like sound waves in air or the ripples made on a pond's surface when someone throws a rock in the water."

"Gravitational waves are produced by masses moving through space-time in a special way. The simplest system that produces gravitational waves is two masses orbiting their common center of mass.
One of the most common such system is a binary star system two stars orbiting each other's common center of mass. It turns out that about half of the stars you see in the sky are members of a binary system"

"Albert Einstein’s general theory of relativity predicted the existence of gravitational waves — distortions in spacetime — but assumed that they would be virtually impossible to detect from Earth."

"Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The kind of motion may be translation (or motion along a path from one place to another), rotation about an axis, vibration, or any combination of motions."

"The motion of a body that is under the gravitational influence of two or more other bodies is very complicated and can be calculated properly only with large computers. Fortunately, astronomers have such computers at their disposal in universities and government research institutes."

"Astronomers made 35 new detections of gravitational waves, or ripples in space-time, between November 2019 and March 2020. The cosmic waves were largely created by pairs of merging black holes, but several were born of rare collisions between dense neutron stars and black holes.
It's a giant leap from when just three gravitational waves were detected between 2015 and 2016. This brings the known number of detected gravitational waves to 90 from 2015 to 2020."

"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."
