Now the question is, what time is it in voyager 1? With time dilation, the "now" on Voyager is out of sync with our now. I was watching star wars recently and when Han Solo casually say "we should be in Alderaan at 0200 hours", I paused for a second. What does that even mean [0]? Traveling through space is challenging today, but after we figure that out, we will have to face the problem of time keeping across the galaxy.

Barring relativistic travel, it’s not dissimilar from the problem seagoing voyagers faced on long trade routes. Ship time is set based on the convenience of the passengers and the route.

  Why a couple minutes?

    > Why a couple minutes? …because that’s what the math says? Based on Voyager’s relative velocity it’s expected to be about 2 seconds younger than it would have been had it stayed on Earth.
