> After all, the shortest distance between two spacetime events isn’t a straight line any longer. That's wrong. It's still a straight line, just along the geodesic of the local spacetime. It looks curvy if you bend and flatten spacetime into a Euclidean space, but that's because you bent it! Light in a vacuum always travels in straight lines. Gravitational lensing isn't gravity bending the light, it's the light traveling in straight lines through highly curved space.
