So after tuesday's episode, i got to thinking 'if the ancients wanted to go find out about this message being broadcast from the big bang origin, they'd HAVE to know that it's physically impossible for them to survive any trip there because it'd take tens of thousands of years for their (at that time) fastest ship to get there. How would you, an Ancient, who's very advanced and very smart, last long enough to see the awnser? Stasis pod? nope, time goes very slowly but still goes. Loose power to the pad and your toast. How about ascend? well if you ascend you are energy and you probably already know the awnser to the question. But what if.... ascension was devised as a way to endure the long distance travel to this place destiny is going? what if the ancients, figuring it would be far easier to endure the rigors of a trip that long if you could get rid of your body and exsist in say the Destiny data bank? There's episodes that support this.
The guy that was injured and put in the chair (i forget his name). he disappeared... or did he? the ship engages it's FTL drive right after he disappeared.
The ship seems to know it has people on it and actually are testing their commander to make sure he's fit to command.
Rush uses the chair to get the code for the bridge.
My thinking is that the crew didn't leave destiny, their still abord. and they used the chair to sort of semi ascend. their not free flowing energy, but instead contained within the destiny's masive computer system. and their just as interested in the humans that have come aboard as they are in destiny's final destination....
Just food for thought.
