Frame dragging is a theory which says that space is elastic, and particles in it will exchange energy with it. In the scientific world, elastic means that when you apply a certain amount of force to an object (which will cause it to bend) and then remove the force, the object will return to its original shape and energy state.
This does not contradict the theory of special relativity, since it is space itself that is expanding.Frame-dragging, in which a rotating mass drags along the space time around it. Technically, general relativity is a metric theory of gravitation whose defining feature is its use of the Einstein field equations.
