← ScienceWhich effect on observed redshifts results because intense gravity compresses spacetime?
A)Gravitational blueshift decreases relative change
B)Hubble constant measurement becomes accurate
C)Gravitational lensing magnifies objects
D)Observed time period of distant event increases✓
💡 Explanation
Spacetime compression near a massive object causes gravitational time dilation. Observed time period of a distant event increases because photons lose energy climbing out of the gravitational well; therefore, the light redshift increases rather than blueshifting, affecting interpretation.
