You're not thinking the problem through. If the path is bent, light
will still follow the geodesic (shortest path). This path length will
change but so will the time it takes to travel from A to B. The change
is time is dependent on the path change. They both decrease so the
ratio stays the same and thus c is maintained. Then the universe and
Einstein are happy.

Subject: E=mc^2?
A Question:
E=mc^2... C is relative to the vacuum(gravity bends a photon's path, the
speed decreases). Would that mean that c, and hence E=mc^2, are relative
to
the vacuum around them? I don't know where I got this question... Just
occurred to me...
