If gravitational waves are considered as a repulsive force emanating from a collision of heavy objects and dark energy is similarly considered as a repulsive force, is there a link between those two phenomena as viewed from this common repulsive behavior? If dark energy is the leftovers of the annialations (collisions) of the vitrual particles of space, giving the small forces that are everywhere, inflating the cosmos in a smooth, continuous fashion, thus leaving dark energy as an aggregate of these smallest possible gravity waves, with ultra heavy objects detected by LIGO as tending toward the largest?

IF they were; alas, they are not.

if they are "pushing against" space time over here, they are by definition, repulsive it would seem...even if the push is somewhat negated within the quadrapole network, it seems there should be some "residue" of an inherent ineffeciency of the process, leaving a small overall repulsive force

so, I guess you don't think much of the idea that virtual particle collisions represent the mechanism that causes dark energy and/or that they indeed can be considered as the smallest possible gravity wave generators.  I certainly see your point that regular gravity waves are not generally repulsive, however it does seem that any physical process, and that includes the transfer of gravity waves, must have some underlying inefficiencies, however small, as they travel through space. Since there is a movement from point A, the black hole, to point B, LIGO, it seems self evident that there is a "push" going on at the level of the inherent inefficiencies of that system.
