Trope-a-Day: No Warping Zone

No Warping Zone: You could, in theory, put a wormhole pair anywhere you liked – high mass notwithstanding.  The traditional location out on the edge of star systems has more to do with size, ease of construction and transport, accessibility and defensibility, and minimizing the consequences of their extremely explosive, if mostly theoretical, failure mode if something should go Horribly Wrong than any sort of physics-derived limitation.

Recall, for example, the Ulijen Disaster.
