SUMMARY
General relativity establishes that no object can exceed the speed of light when measured against local landmarks. Local landmarks are defined by their proximity and the curvature of spacetime around them. As spacetime curvature increases, the effective distance between local landmarks decreases, particularly in strong gravitational fields like those near the sun. The boundary between local and distant landmarks is determined by the deviation from flat spacetime exceeding the limits of instrumental error.
