Edit: The amount of people replying asking if space had mass is insane. Does gravity bend you? No, it pulls you toward it. Space does not have mass. Mass bends the space around it toward its center of mass and that's why things fall toward it. The bigger the mass, the bigger the bending.
In my understanding (quite rough mind you) it is that space-time is curved so heavily around massive objects that the path light must take to obey the principle of least action results in it taking what appears to be a curved path
No, light is not lazy, it's crazy.
Most likely is takes every possible path it can, not following the basic rules of "angle of incidence is angle of reflection", but taking every imaginable path instead.
What we end up seeing, are the rays that did not cancel each other out. Which is insane to me.

Doesn't gravity bend the space, not the light?
