Which mechanism significantly alters observed stellar positions within strong gravitational fields?

💡 Explanation

Spacetime curvature causes gravitational lensing because strong gravitational fields warp spacetime, rather than just attracting objects. Massive objects bend light paths; therefore, stellar positions shift relative to observers, and other options don't directly affect photon trajectories through spacetime.
