Which consequence results when star light passes near a black hole?

💡 Explanation

Star light redshifts due to gravitational time dilation because spacetime curvature becomes extremer near the black hole horizon, stretching the photon wavelength. Therefore, redshift occurs rather than other effects, because those require higher energies or specific particle interactions.
