In the movie Valerian and the City of Thousand Planets, when Valerian and Laureline first approach Alpha, Alex (the ship) indicates that Alpha has traveled 700 million miles after having left Terrestrial orbit. This seems like a very short distance in 400 years (i.e. somewhere between Jupiter and Saturn). Later on this discrepancy seems confirmed when Laureline states,
and the nearest court is 18 light years away.
At only 700 million miles Earth would be much less than 18 light years away. I am assuming there would be courts there?
I have not read the graphic novels on which the movie is based. Is there some other explanation which might resolve the apparent discrepancy? E.g. are there not courts on Earth any more?
