    Remember atlantis is a city, probably not designed for the fastest hyperspace travel though it is capable of travelling to PG from MW very quickly so it can't be that slow.

    If you're thinking of aerodynamics, you're forgetting that it travels through the vacuum of space not to mention the shield would be in place to deflect anything that might be in its path when at sublight and to deal with the stresses.

    What do you mean by "very quickly", and where did you get that idea?

For some reason I think the reason the ancients didn't just take Atlantis back to earth is that their hyperdrive engines aren't fast enough to distance themselves from the wraith and thus would have led the wraith directly to Earth and the rest of the MW galaxy.
    Just a thought.
    For all we know, Asuras could have been on the other side of the galaxy.

    So what? The Pegasus galaxy is only supposed to be about 3 thousand light years across, which means (if Atlantis class ships are fast) it should take less than 30 minutes to travel from one side of the galaxy to the other.

    Another thing to note is that Rodney's experimental puddle jumper with a hyperdrive was able to jump about 2000 light years, and when Radek and he were discussing it, they made it sound like that wasn't very far at all. If Pegasus is only 3000 LY in diameter, then that PJ would be jumping 2/3rds of the way across, which, relatively speaking, is a pretty big jump.

    So I'm guessing the Pegasus galaxy in the show is only loosely based on the Pegasus galaxy in real life. In other words, Pegasus in the series isn't 3000 LY in diameter, it's much much larger (which is lame as hell).
    That's the only way fast ships like the Daedalus could take hours for interstellar travel, and yet still take weeks for intergalactic travel.

    If this is the case, then without knowing how big Pegasus is and having approximate travel times, there is no way to tell how fast or slow Atlantis is.

    What I meant by 'very quickly' was that it is capable of travelling at a similar speed to the deadelus (based on what I know from Adrift), that means that it can get to the PG galaxy in about 20 days, thats if its slower than the DD. Atlantis at that point was only powered by 1 ZPM afterall.

    If you're thinking of aerodynamics, you're forgetting that it travels through the vacuum of space not to mention the shield would be in place to deflect anything that might be in its path when at sublight and to deal with the stresses.
    I was talking about the fact they probably weren't focussing on it being able to go at the fastest possible speed where as on things like warships you would expect them to focuss on it much more.

    You assume that everybody is always maxing out their hyperdrives. This might not be the case, or it might not even be possible, for example, If you were to drive everywhere with your foot down redlining, you're engine wouldn't last very long.

    Nothing happened in Adrift that would allow you to do a speed comparison between Atlantis and Daedalus.

    Except that we know Aurora was damn slow. It was going to take them months to get home if they didn't upgrade their engines. It should only take Daedalus about 14 hours to cross the Milky Way (Pegasus is much smaller than the Milky Way).

    I'm not saying that all Aurora class ships were this slow, but they were until well into the war with the Wraith.

    I'm assuming these ships are traveling at their normal cruising speeds at all times.

    In the episode Critical Mass, Hermiod made some changes to make the engines faster, but he couldn't maintain that speed for very long (less than two hours). That indicates that they were traveling at their maximum (safe) cruising speed.
    Can they travel slower? Sure, I suppose, but why would they if it's not going to damage their engines?

    I'm going on the fact that Atlantis should have beaten them there, not the most sound arguament but at least is shows us atlantis isn't as slow as one of their warships, which i was wrong about their speed(I just watched aurora again), so they could still be around as fast as the DD which was my comment in the first place. Considering atlantis was only powered by 1 ZPM out of the 3.

    You seemed to have missed the earlier discussion in this thread about the whole "Atlantis should have beaten Daedalus" scenario, so I'll recap:

    There are plenty of reasons why the Apollo wouldn't have beaten Atlantis to their rendezvous, the most obvious is that the Apollo remained behind to make sure the Asuran satellite weapon wasn't going to follow Atlantis to their new planet. We know that Apollo remained behind and watched Atlantis leave the planet and enter hyperspace because he reported such to Carter when they reported Atlantis was missing. So, if they hung out long enough to watch Atlantis enter hyperspace, then it's quite possible they hung out long enough to make sure the Asuran satellite weapon wasn't going to follow them (a few hours).

    We also know that Atlantis wasn't going to reach it's destination for 'hours' according to McKay. Daedalus should be able to cross [the real] Pegasus galaxy in about 26 minutes, which means Atlantis is slow if they were going to take hours to get to the nearest habitable planet without a gate that has a big ocean.


    My working hypothesis is that the Lanteans didn't have fast hyperspace drives until long into the war with the Wraith. It was simply a technology that hadn't been discovered until that point. Once discovered, they radioed the upgrade information to their ships out in the field (like Aurora) and those ships were able to upgrade their "star drives" to "hyper drives".

    I just proposed that they might not always be going at max speed to preserve their engines, pardon my in-(un?)clarity. It could explain a lot of things. But in any case you're quite right.

    Ancient hyperdrive engines are probably as fast as a plot hole.

    Right I want to make a few things clear if i may, Atlantis has a interstellar hyperdrive not an intergalactic one, so 10,000 years ago when the Ancient-Wraith war going on they must have stripped doen the hyperdrive for parts of whatever and left the main stardrive, hence travel between stars the stardrive, anyway the daedalus can travel with ZPM power to atlantis in about 4 days, with 3 zpms if they could utilize that power could get there in about half a day or even less maybe like 0.0000000000078 nanoseconds with power like that, we just dont know.

    Finally i think atlantis could go at an infinite speed because simply we dont know what kind of speed hyperspace occurs at it could be 10 powers of light speed but the speed would be very fast.

    If the PG galaxy is based on the real 1 it is about 3 million ly away, for the deadelus to get there in 18 days it would need to be travelling at around 7000 ly per hour, slower than 10 power the speed of light. (Presuming the galaxy is based on reality)

    It's pretty clear that Pegasus is based on reality, but not very well. It is said in SGA(I think when they were talking about the Gate Bridge) that it's roughly 3 million light years from the MW, which is consistent with the Pegasus Dwarf Irregular galaxy, but there's too many inconsistencies. In reality, that galaxy is roughly 6 thousand light years in diameter. If the Daedalus can travel from the MW to Pegasus in 18 days then thats roughly 7000 light years/hour or 165,000 light years/day, as stated before. With those kind of speeds the Daedalus would be able to cross the Pegasus galaxy in less then an hour.

    The writers probably took a real galaxy/ dwarf galaxy and manipulated the idea of it to suit their purpose so they can make it as far across as they like.

    Perhaps you HAVE to travel slower inside the galaxy. There are larger objects located in the galaxies than in intersteller space you know. There was an episode i cant recall which one where a gravity well (i think it was. somethin with a large gravitational pull) disrupted the naquadria reactor and burned it out. Maybe its just like that in a galaxy. The objects arent physically there but you still have to avoid them because their gravity has affects on hyperspace travel.

    Dont think thats a real good explanation - galaxies still aren't very dense. Two galaxies could fly right through eachother, with the greatest likelihood beinh that not a single collision occurs.
