Superficially, there are many similarities between gravity and electricity; for example, ...
Gravitational waves are usually produced in an interaction between two or more compact masses. Such interactions include the binary orbit of two black holes, a merge of two galaxies, or two neutron stars orbiting each other.

Gravity waves refer to different (but basically similar) concepts in fluid dynamics and electrodynamics.

Definition: gravitational waves: Ripples in space-time caused by the motion of objects in the universe. The most notable sources are orbiting neutron stars, merging black holes, and collapsing stars.

Gravitational Waves
Disturbances or ripples in spacetime predicted by the General Theory of Relativity due to changing distributions of mass such as the spindown of a neutron star binary system or the implosion of a star during a supernova.

Gravitational waves may be viewed as coherent states of many gravitons, much like the electromagnetic waves are coherent states of photons. Projects that should find the gravitational waves, such as LIGO and VIRGO, are just getting started.
gravitational wave - (n.)
propagating field predicted by general relativity to occur as a result of any large-scale change in the distribution of matter (as in the collapse of a star).

gravitational wave The gravitational analog of an electromagnetic wave whereby gravitational radiation is emitted at the speed of light from any mass that undergoes rapid acceleration.
^ Gravitational waves have never been directly detected but are widely believed by the scientific community to have actual existence.

Just as accelerating charges can emit electromagnetic waves, accelerating masses can emit gravitational waves.
One event that might produce a large gravitational wave would be the collision of two black holes. If there were black holes in a binary system they would slowly spiral together.
It would be the first space-based mission to attempt the detection of gravitational waves -- ripples in space-time that are emitted by exotic objects such as black holes.
The resulting gravitational radiation (or gravitational waves) waves ripple outwards through space, traveling at the speed of light. Gravitational waves vibrate in a plane perpendicular to the direction in which it is propagating.
The magnitude of the primordial density fluctuations and gravitational waves they produce may also be too high for some particular models. There are, however, much more serious problems associated with these scenarios.

Radio science subsystem: Searches for gravitational waves in the universe; studies the atmosphere, rings, and gravity fields of Saturn and its moons by measuring telltale changes in radio waves sent from the spacecraft.
Prediction: objects with mass should create ripples in the surrounding spacetime as they move, called gravitational waves. These waves do not travel through spacetime, but are the oscillations of spacetime itself! ...
Using this binary system, they observed indirect evidence of gravitational waves and also tested the general theory of relativity. Several dozen binary pulsars are now known.

With my secondary mentor, I used a ... CAD (computer-aided design) tool to iterate the design of a proposed small explorer satellite. This satellite was going to use the aforementioned optics to research gravitational waves.
If the two have been drawn close enough together by interaction during a common envelope phase, they can spiral together by the radiation of gravitational waves predicted by relativity theory.
