Which phenomenon is observed due to spacetime curvature near black holes?

💡 Explanation

Gravitational lensing occurs because spacetime curvature bends light rays near massive objects. The process, called Shapiro Delay, increases light transit time rather than increasing speed; therefore, the distortion forms rings, rather than expansion, or changing mass.
