Hrm, interesting
I had another thought, which I guess will be explained in the pilot I hope, how are they able to gate to the ship in the first place, and why can't they gate back, i.e. in terms of power source. Surely the Ancients would have thought of a way to send themselves back to the MW galaxy from the Destiny and left a few power cells there, heh.
Also, considering the Destiny has been planting Stargates in who knows how many galaxies, how far in terms of distance will they be able to travel with whatever power source is on board the Destiny? Can they only travel within a gate network of the galaxy they are in, or does it allow them to gate to other galaxies the Destiny has dropped off gates at, and if so what is the distance limitations? If they find enough power could they gate all the way back to the MW?
So many questions and the series hasn't even started yet
