And our depth chart is showing . <| sep |> I don ' t know why that bugs me so much but it does . <| sep |> I really don ' t like the flipped day cycle in Moon , I find it really jarring . <| sep |> Its believed that technology provides a natural population cap for people . Its somewhere around 10 to 12 billion . Even if we assume that some cultures maintain high birth rates into the future , by Star Treks time humanities population might be 14 billion . We know a colony ship can carry tens of thousands , but early colonies were probably started with fewer people . Also it really bothered me too how often it was Earth . I just wanted one reference in the entire show to say It will take us 70 years to reach Deep Space 6 or Colony X just so we know they aren ' t literally heading to Earth although it does literally end with them at Earth , so maybe it wasn ' t untrue . I remember one season the Voyager commercials on TV a generic watch the show commercial , not episode of the week would show the characters saying where home is . We had a whole lot of Earth mentioned .
