I think, most close point, to think of it like additional dimension. For example, imagine we live on 2D infinite plane, and once found out, that in some places, moving on for example for 1km, we see same shift as with moving linearly (to be more exact, by some arc or some polygonal line) by other route for 100km (really need much less to prove topological defect, just standard scientific 3-sigma difference from our model is enough), so this mean, we have crease on space-time topology (and possible, some sort of wormhole, or just holes on plane and controllable way to navigate/move from one hole to other and move between hole and our plane).
