White holes have been predicted by general relativity since its earliest solutions, yet none have ever been observed. This paper proposes that the reason is not physical absence but geometric inevitability. It argues that black holes and white holes are not separate objects but two faces of the same horizon, seen from different observer positions. Because all observations are made from outside the horizon, every horizon appears as a black hole, making the “white hole face” structurally unobservable as an independent astrophysical object. Using thought experiments, geometric reasoning, and the Kruskal extension, the paper shows that the absence of white hole detections is not a physical mystery but a consequence of perspective.
