actually this can't be stated in such a convinced way. When we whach (even by inteligent experiments) light, it appears to be straight and go in straight lines. So, I would say this is relative. The shortest path possiblein the space (actually is in space-time) is called geodesic line (knowledge adquierd from AntonioLao's posts).
