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 presence of mass changes the meaning of distance around an object.

All objects follow the shortest path between two points, (known as a “geodesic”).

Because distances between points are now “warped” near the mass, the shortest path between two points is no longer a straight line.
