| 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.
oh. Sickeningly simple, once I stop to think about it....
