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?
We are talking about distances that are so big, there is no comparison that makes sense. Nothing else IS that big. The numbers are literally "astronomical". If you're struggling to wrap your head around it, you're doing it right.
"Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space." -- Douglas Adams
So to catch up, you would have to be faster. Let's say you were able to travel around the equator in 15 minutes, so you're gaining 30 minutes per equator. If my napkin math is right, it would take you roughly 45 years to catch up to voyager.
This probably wasn't your intention, but putting it in terms like this, for me anyway, actually drives home just how short a distance the Voyager probes have travelled.
