Which mechanism distorts spacetime around black hole event horizons?

💡 Explanation

Gravitational lensing occurs because mass concentration intensely curves spacetime near a black hole. A photon's path bends; therefore, strong lensing effects are detected, rather than Hawking radiation or frame-dragging alterations, as those have distinct detectable signatures
