When things move, they create waves. For example, if you shake a stick back and forth in water:water waves. Vibrate a piece of metal back and forth really fast: air pressure waves.Shake some electrons back and forth really fast: radio waves. And yes, shake a planetor star back and forth really fast: gravitational waves.Gravitational waves happen because the effects of gravity don't travel outwards at infinitespeed – so if the sun were to suddenly jump a few hundred thousand kilometers to the side,the changed gravitational field would take time to pulse outwards. And if the sun shookback and forth and back and forth, instead of a single pulse, you'd get continuous gravitationalwaves.So what's doing the "waving"?In the ca...
