It was very strongly implied that shortly after they gated in, the ship jumped into its ftl mode: the color shift and stretch thing happened shortly after they all boarded, and again right before they stopped at the planet.
I didn't see this when they first arrived. Of course at that time my wife and kids were watching with me (when it first came on) and so it's possible one of them distracted me so that I didn't notice it. I did notice the waveform distortion at the end, after attempting to dial Earth, so, it would be consistent if it did happen at the beginning also (I take your word it did indeed happen) to think that on both occasions the ship was at normal space-time in order to make use of the Stargates. In that case it would mean the ship does apparently have to be at normal space-time to use the stargate. That would also be consistent with previous other shows, but, it still doesn't preclude FTL use of the stargate, just makes it unlikely it operates any differently based on what we now know.
I could swear they said (or at least it was conjectured by some character) that the ship was indeed intended to travel really, really far away, and then be later crewed after it had reached something/passed a threshhold/etc. I don't think there's any need to guess at that, it was given to us.
I didn't hear this either, but, there were a couple of times I walked outside during the show, mainly around commercial times, because we had a full moon. I was toying with the idea of setting my telescope up and moon-gazing then, but thought the show was good enough to skip it for one night. So I didn't, but I guess it's possible I missed this conjecture while I was outside.
If it was conjectured by one of the characters (anyone know who or at what time in the show - I would like to know who said it, in what context, and what exactly they suggested - hopefully I can see this in rerun sometime) then it would be a logical conjecture, given the other evidence, and I would agree with them. It seems the most likely possibility. (I hope though it will be remembered it is, like my deductions, and the deductions of others, just a character conjecture based on the best available evidence at the moment. A likely, though not necessarily the only explanation, and certainly not the truth - that won't be known until other evidence is gathered or discovered. And I hope this show continues to follow the path of best conjecture or best possible conjectures, rather than trying to explain everything all at once. In far too many television shows the first suggestion or conjecture is just assumed to be correct, handed to the audience as the way things really are and the plot proceeds from that point on as if the initial conjecture was necessarily the only or the only correct one. It's a juvenile, even child-like way to describe problems - especially when operating within a totally alien or unknown environment - because very rarely does it happen that way in real life. It's a way for the writer to "project what he knows" through the character without any real reason for the character to really know that thing, merely because the writer doesn't want to take the time to describe events in enough detail to fully explain the real situation. I hope instead that they will discover situations and problems, consider possibilities, gather evidence, make conjectures, and discard possibilities as it becomes apparent their initial speculations were incorrect, or at best only partially correct. Which illustrates for me what also bothers me about too many television dramas, only rarely are main characters or "smart characters" seen to be wrong in a particular situation, or to have drawn the wrong conclusions, even though it is quite justifiable for them to do so given the circumstances. Stargate Atlantis, which I liked, was nevertheless especially egregious about this regarding their smart-guy and super-dooper scientist. But real scientists are never this way, and neither, generally speaking, are smart people. Being wrong is a necessary part of becoming smarter in real life. I wish more fiction writers understood that. Instead they far too often make the smart guys or the problem solvers always or very nearly always right the first time, when that almost never really happens in life. The smart guys are just the ones who won't quit when others do, or are willing to consider all possibilities when others won't. And they learn just as much from mistakes as they do from successes.)
But the idea of the waiting starship, or the starship in situ, does have a number of problems that will also need to be addressed. Like if the ship is only visited rarely then why was the life-support operational just coincidentally when the humans boarded (unless it was being tested or prepped to receive a crew, and if so, then tested by whom, and where is that crew)? Otherwise it would be a large waste of energy to run it constantly. Why was it inactive (as to motion), but had an active life-support system? Was it long abandoned - after all the assumed builders are long gone for the most part - and just sitting dead in space, but with the life support still active? That's an illogical means of operating considering power consumption rates, unless the crew had abandoned ship in an emergency and the ship had expected them to return quickly.
Another thing that is bothersome is this - was this the only type of ship like this? Was it a prototype or unique ship design, so that only one was ever built? I mention that because of the fact that as far as anyone knows yet there was only one gate and one gate location capable of dialing the ship. Why? That's incredibly risky if the ship is unique or a prototype because if anything happens to the one gate then you have in effect lost not only your means of boarding the ship, but also presumably your means of contacting an unmanned ship. If it was a manned ship then this would demand other gates so that you would have safe means of retrieving your crew if necessary. Otherwise lost or even just malfunctioning home gate and you've no way of direct contact with ship gate, and the suggestion thus far is that ship gate is ranged when dialing out. (Meaning home gate somehow picks up the slack on return gate voyages back home, or the ship as we know it is barely functioning at real capacity because of real damage or because it is simply just not fully active, or Rush is lying about on-board ship capabilities. Maybe all of those.) Surely, just as a security precaution, if you went to such expense to build such a vessel, and the mission was important at all, you would have built in redundancy means of reestablishing contact through other gates.
If there are other ships of this type or class, undertaking similar missions then naturally you could not risk them all being accessed by a single, unique stargate. That would be extremely risky. A real security threat. Either way I would not risk access to either a unique prototype or a fleet of ships through a single access point. I guess they (the writers) could say the one location for the nine chevron stargate has very unique properties, but in all of the universe, including all of the other galaxies visited by this one ship, they could not replicate conditions enough that they could only build the one peculiar portal? It seems very unlikely to me. Even more than one "Atlantis" was built, for obvious reasons. I'd build in more than one method of accessing such a ship. Even if I only built one such ship.
2.) The 'Destiny' is an old ship, a very old ship. Chances are that it was send on it's journey before they equipped all their equipment with gene sensors. Maybe it's only on a couple of very secure systems.
3.) The 'Ancients' assumed that they might not be the race that would be using the 'Destiny', they would Ascent before that or their genes wouldn't be the same by the time they would use the ship.
Interesting conjectures. For one thing they might have very well anticipated human occupation if no. 3 is correct. Something I intuitively feel is a real possibility, I just have no evidence to support the idea. I cannot say why exactly but I just feel as if either the builders, or the users, or the ship itself was anticipating the human occupation.
If 3 is not correct then where are the users of the ship, and how long ago did they make last contact. And if the mission of the ship was to place stargates in other galaxies then, and Earth was the ship departure point (I think someone aboard ship suggested it was - Rush?) then was Earth the real departure point or merely the first plotted colonization point on the starmap they accessed? (Did Rush assume the starchart he examined was the only starchart or navigational chart or the first one and that meant Earth was the departure point? If it was then was the ship built there? )
The show has a number of interesting possibilities as far as the storyline goes. I hope they continue to unfold more mysteries as often as they start reducing others.
Well, I've got to prep for flight training. See you guys later.
