← ScienceWhich mechanism explains increased gravitational lensing when photons pass close to supermassive objects?
A)Spacetime curvature by immense gravity✓
B)Quantum entanglement near event horizon
C)Doppler shift inducing photon bunching
D)Cherenkov radiation through accretion disk
💡 Explanation
Gravitational lensing increases due to spacetime curvature; massive objects warp space, bending photon paths because light follows geodesics in that curved space. Therefore, lensing increases rather than being caused by quantum effects because these don't affect macroscopic paths.
