Which effect occurs when measuring a distant object's spacetime near a supermassive black hole?

💡 Explanation

Gravitational redshift happens because photons lose energy escaping the intense gravitational field through the spacetime around a black hole; the **Shapiro delay** decreases their observed frequency relative to the source, therefore they appear redder, rather than exhibiting blueshift phenomena.
