Just rewatched Stargate Universe and something they said at the beginning of S1 confused me: They stated that the stargates seeded by the seed ships and the one on board Destiny were "less advanced" than the Milky way or Pegasus models. What makes the Destiny gates "less advanced" is the fact that they can't dial beyond a certain range; they can only dial "planets in range" which usually only number in the 1-4.
We know this isn't a power issue - the ship can fly through a star after all, pretty sure it can compete with a Naquadah generator to power a gate. Destiny's stargate can dial the nine chevron address to Earth if it has enough power.
So, the less advanced gate can't connect to stargates a few hundred or few thousand light years away, but can connect to a stargate several billion light years away? What could possibly make those gates be so primitive yet so equally advanced? Shouldn't destiny be capable of dialing the entire galactic network, just like any other gate we've seen before SGU?
