I guess the first thing to say is they're a consequence of general relativity thatwhen you get as far as writing down the equations of general relativity and starttrying to solve them you find that some of the solutions involve these wave solutions.They're distortions of the spacetime that propagate out. -I mean they're importantfor lots of reasons they're important because they are a prediction of generalrelativity so actually if you then detect them you've found furtherconfirmation that general relativity is actually right. -Whenever matterpasses by through some region of spacetime it will distort the spacetime just likeyou would distort water when if you put your fingers through water and wavespropagate out this is a propagatio...
