The dent in the rubber sheet that the earth currently sits on - hence the whole curvature in spacetime thing. As far as I know no one has figured out or found gravitons yet, so it's just a theory. Which I assume means there should be a few gravity-deniers out there to give themselves a break from global heating denial. :)
