I've got a silly question, could there be some long term effects of an object that had been there? For instance, could there be some kind of elasticity or residue, something like radiation that could cause a dissipated gravitational like effect long after the thing has moved on or otherwise "disappeared" in some way? In this very likely wrong model maybe the thing causing the effect visited hundreds of years ago and was just passing through and so it's no longer directly observable...
