I beg anybody to rephrase it understandingly with using some units similar to football fields. Is it possible to launch a little cheap rocket with a transmitter just to correct Voyager's position?
If it's 15 billion miles away (sorry for my Freedom Units), it is 22 light-hours away, or 0.0026 light years away (unless my Google-fu is way off). If we could move at the speed of light, which we can't, it would still take nearly a day to get there. So if we were on the Enterprise moving at Warp 1, it would take a day to get there and reorient it back towards Earth. If we could move at Warp 10, we'd have already been there and fixed it.
