Light, despite being massless, is affected by gravity due to the curvature of spacetime as described by Einstein's General Relativity. Photons, the particles of light, follow the geodesics of spacetime, which can lead them into black holes. This phenomenon explains how black holes can "suck" in light, as their immense gravitational pull warps the surrounding space. The discussion references Msg. #8 in the FAQ thread for further clarification on this topic.
PREREQUISITESPhysics students, astrophysicists, and anyone interested in the fundamental principles of light and gravity, particularly in relation to black holes.
