If light has no mass how can a black hole pull it by gravitational force?
That makes sense. But why is the gravitational force of a black hole so strong that it can even pull in light?
Black holes are incredibly massive objects that have an immensely strong gravitational pull. Because of their mass, they can warp the fabric of space and time, creating a gravity well that is so deep that nothing, not even light, can escape it once it gets too close.
