Which effect on observed star positions arises when light travels through a galaxy's dense spacetime?

💡 Explanation

Gravitational lensing occurs because spacetime is warped by the galaxy's mass, therefore, starlight bends rather than travelling straight. Redshift is a different effect from expansion, rather than spacetime curvature, involving decreasing photon energy.
