And one of the slowest wormholes every created. Seriously though, if they achieved that by accident then how has Starfleet not figured out how to replicate it reliably 100 years later.
In DS9, Tril scientists tried making a wormhole but failed. There are issues with stabilizing the wormhole so it lasts a useful amount of time in a sufficiently safe state. I had forgotten, but in Voyager the MIDAS array is used to create a microwormhole to communicate with Voyager. So, they achieved it on a small scale. Apparently they called it hyper-subspace technology.
http://memory-alpha.org/wiki/Hyper-subspaceIt may be a bit lazy, but it's also somewhat scientific. Whenever there is a large sample set it is prudent to delete outliers, in order to ensure that the calculations on the rest of the data is consistent, and not put out by anomalies. If we take the same approach for canon, with one episode that was never mentioned again, and has been disowned by it's creators, then it becomes rather obvious that the best course of action is to remove it from all further calculations, in this case discussion. And there's plenty of reason to include real world concerns into the discussion of canon, especially when mistakes and continuity errors have been specifically mentioned to be errors on the part of the production team. In this case we have everyone who was involved in the episode, including some of the actors, saying that it probably shouldn't be considered a proper episode.
I go by if it is in, then its in. There are too many conflicts with official statements, so I ignore the lot of them. The other problem is that even if ignoring it is scientific, it's only that way when looking at it artificially. I look at it as irrevocably part of the universe unless even the wildest attempts of explanation don't even fit thematically. Ignoring it only because it was no mentioned again is also bad form, it would involve ignoring lots of Voyager and the other series simply for never being brought up again, or being brought up in ways different from the previous episodes. We would need to ignore the coaxial warp drive, quantum slipstream, and plenty of other things as well. For instance, Riker's performances in the movies, his constant refusal of promotion, yet getting a command in Nemesis, and all of that in relation to his performances in TNG. There is no good explanation for that, but ignoring one (TNG) for the other (movies), or vice versa, is no good either. The best explanation I've seen is that everyone was acting stupidly, not just Riker, but that has its own problems.
That's true, but it would mean that a group of Starfleet rejects with a single ship's resources managed to achieve more with high speed FTL than the whole Borg collective has managed in their centuries of existence, which is even more incredible considering that they've had transwarp drive for quite a while, and access to that area of space (the "new dilithium" is much closer than the Federation, and they seem to have no trouble getting there if they want to). Quite frankly that sounds ridiculous.
Borg aren't a good example, the only thing they may have ever researched on their own is the Omega particle, and they only explore for civilizations. To do what Voyager did would require the Borg to have found a group who also found the special dilithium, who would in turn point the way for the Borg. The dilithium also means breaking warp 10 is not a matter of technological genius, but only one of random chance. It would only become a matter of genius if the dilithium can be artificially created.
I think it's more that transwarp is a term for anything that uses subspace for FTL, but does it in a different manner to regular warp drive. Or it could be that they were all names for the same thing, with the exception of the last two, which I don't really remember. Which episodes were they from?
There is no fixed method for transwarp travel, as the Borg have several variations, there is the Dinosaur version, and the quantum slipstream version. Not to mention coaxial and wormhole.
Borg used to appear to be able to lay conduits as they went, and they would be accessible with some sort of tachyon signal. I think laying the conduits was slower than using pre-layed ones. Those conduits would also disappear over time, and the signal could be changed, meaning they could be relocked if anyone discovered the code. In Voyager we then see the transwarp network, which leads some people to believe the Borg actually have only one form of transwarp, but I prefer to think of it as three tightly connected forms. Path laying, path reuse, and path fixing. It also fits with Seven saying Quantum Slipstream is similar to Borg transwarp. I almost forgot that the Enterprise-D used a signal to open such a conduit, and there is Voyager riding the network conduit in the final episode, but we also have the Delta Flyer using a Borg transwarp coil on several occasions with no mention of pre-existing conduits. You don't need a special piece of equipment to use existing conduits, so using a coil tells me they must make new conduits on the fly. That's too many episodes to name, and I don't know the names anyway, but there aren't that many Borg episodes, and they're all the TNG and VOY ones, not the ENT one. The only conflict is how in "Scorpion" the Borg say it would take months to drag Voyager home, that should have been bullshit, but no one says anything.
http://memory-alpha.org/wiki/Transwarp_drive#Borg_transwarp_driveThe Dinasour one is the Voth transwarp drive which looks exactly like normal warp except for double long star streaks. VOY: "Distant Origin"
http://memory-alpha.org/wiki/File:Voth_research_vessel.jpghttp://memory-alpha.org/wiki/Transwarp_drive#Voth_transwarp_driveCoaxial warp drive is a space fold drive. It's another one of those drives that could have got Voyager home but was never used, like Warp 10, and Quantum Slipstream. I include QS because they only needed to use it bursts to use it safely.
http://memory-alpha.org/wiki/Coaxial_warp_driveOf course they matter, it's the reason the line is the way it is, it has all the bearing in the world. Intent is just as important as content, especially when it comes to canon. Now intent cannot override canon, but it does provide a measure of perspective about why something happened the way it did, why a character said their lines that way, and so on. I don't believe I said to throw it out because of any contradiction, it was because of a considerable contradiction which was stated several times, quite specifically and with "scientific" terms. It's not just a single conversation either, they mention it several times throughout the episode, so that theory doesn't hold water. The events may match up, but that doesn't explain the dialogue, and all the other nonsense that was portrayed as "science" in the episode.
The behind the scenes intent can help some, but can't be relied on. The intent was to create a commentary on how evolution doesn't have to be stronger and smarter, but it fell on its face and was about our fixed genetic destiny to turn into primitive externally gilled newts who can fly space ships.
Yes, it's a mess, so stop pointing out negative explanations of none of it existing and being impossible. Come up with an positive one that actually explains something.
