Question:
How can the gravity of a black hole pull light towards it?



Replies:
Light follows a path which is the shortest distance between two points in space-time. Gravitational fields are associated with curvature of space-time. In the presence of a strong gravitational field, light follows this curved space time. Thus the path of the light deviates from what appears straight to "us", apparently acted upon by the gravity.
