It's like the eternal sci-fi novel come to life. We get to see a set of characters interact just as they always do, but without some of the control of our day-to-day industrial context. Load the colonists on their ship and watch them continue their arguments long centuries after the original subject was forgotten. Hatfield-McCoy, Gunfight at the OK Corral, Serbs versus somebody 500 years ago, Muslims versus somebody 800 years ago. On and on it goes, lightyear after lightyear. Who knows, when they finally arrive at their new planet the first thing they will do after leaving the ship and breathing in the fresh air is duke it out. A thousand years later their progeny will still be arguing. That's what the mirror reflects.
