Scientific theories aren't so different from explanations of any other sort. None of them (whether science or otherwise) are descriptions of "reality"; they are all models. But anyway that seems off to the side of what you were asking for, which is an explanation (i.e. reasons or causes), not direct correspondence to reality, which is a different issue. Scientific theories, like other theories, do have "explanations", in the sense of broader or more general theories. It's true that there are some scientific theories (arguably including gravity) that do not yet have good explanations, but I'd guess that in all such cases, people are still looking.
