    Gravity doesn't affect light; it affects space and time. When gravitational lensing magnifies distant objects, it's bending space. Light, which travels in a straight line (to the best of its knowledge), follows this curvature and seems to bend.
    As for time: I'm not even going to start on dilation. However, for a practical (yeah, right) example of time dilation at work, check out http://robertelliott.org/science/planets .

    Sorry. Just realised that I wasn't that accurate. My page above is concerned with speed, not acceleration (acceleration == gravity according to general relativity). However, the same rules apply.
