Which mechanism causes lengthening photon transit times near black holes?

💡 Explanation

Spacetime curvature causes photons to expend energy escaping a gravity well via gravitational redshift, because it effectively increases the distance traveled. Therefore light arrival is delayed, rather than effects based on particle transformation or emission.
