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

Gravity doesn’t bend light. Gravity bends the space that the light is traveling through. The light goes “straight”, but the space is bent so that “straight” appears “curved”.
