Which risk increases when a gravitational lens enhances distant starlight?

A)Increased chromatic aberration
B)Spurious time dilation analyses
C)Reduction in available photons
D)Decreased parallax measurement accuracy

💡 Explanation

In strong lensing, variations in spacetime curvature near massive objects cause different light paths resulting in variable arrival times; because mass-energy equivalence influences the path length, misinterpreted arrival times cause incorrect cosmological distance estimations. Therefore spurious, incorrectly interpreted, time dilation assessments will confound researchers rather than improving accuracy.
