    Welcome to PF :)
    Gravitational waves are ripples in the space time. Moving masses like stars and black holes do create the gravitational wavers. They are not yet detected physically but it is just a concept stated by Einstein in his theory of relativity. Well, you can go google it for more info and if you have any more doubts, free feel to drop them here :)
