Frame-dragging
Since the energy absorbed by spacetime has to go somewhere, many scientists predict that spacetime would be "bunched up," or folded. This can also be phrased as a curvature (bend) in spacetime. This would indicate that the particle generated gravity. The reason that this theory is called "frame dragging" is probably due to the effect of particles effectively "dragging" or "grabbing" spacetime as they spin. Not only would space be curved, but time would as well.
