what are gravity waves? i am guessing that they are some kind of oscillations in the space-time "medium"?

but gravity waves are not the normal carrier of the gravitational force? otherwise, because its an oscillation, the force wouldn't fall off with the square of the distance. so what special circumstances create gravity waves? where do they come from?
A simple explanation is that gravity waves are to gravity as electromagnetic waves are to the electrostatic columb force between charges. They are related, but separate. Accelerating charges can produce electromagnetic radiation, and accelerated masses can produce gravitational radiation.
