If light has no mass, how does gravitational force bend light inwards

Question

In the case of black holes, lights are pulled into by great gravitational force exerted by the dying stars (which forms into a black hole). If light has no mass, how is light affected by gravity?

Answer 1

The easy answer is that light is not without mass. It has mass but such an infinitesimally small amount that it can be considered for nearly everything to be neglible. However, a black hole has such stupidly absolutely insanely strong gravity that light has enough mass for it to be considered.
