It is my understanding that C (the speed of light) as a limit applies to matter and energy travels at that speed, it does not apply (according to theory) to space itself, and space can expand and move faster than C. So as space expands and moves away it carries the galaxies with it which would appear to move faster than C but may not really be moving very fast at all in the space it is in.
