Well sort of. I'm a chemist not a physicist so....gravity is the result of mass and impacts the fabric of space time. IOW it causes a deformation in space time, a gravity well which impacts other masses. A moon falls into a planets gravity well and stays captured there.
I'm thinking that a 'gravity wave" is a propagation of such a disturbance in space time but of very very small magnitude. At least that is how I think of it.
I'd like to hear Dr Tyson explain it.
