The bonuses for both the Vasari and the Advent colony capital ships make sense. Plus you can see them reflected in the planet info when hovering over a planet. What exactly does "free resource extractors will be built at higher levels" mean? That construction on them proceeds more quickly?

Can trade ships traverse worm-holes? If so, are there prerequisites? I started a single-player game on a map where each solar system is connected only by wormholes. In my second solar system, my colonies all have low allegiance. 1) How do I effectively use broadcast centers? 2) Does this culture spread across worm-holes? 3) Is there a better way to keep allegiance up?
