Hyperdrive vs Slipstream

[fallenexile452]

Indeed, planets, suns and the like should and is not a problem in Stargate hyperspace (normally, only a few things, like collapsing stars and black holes can be), that is why I am refering to Star wars hyperspace as a nerfed form of warp, in Star wars they can crash into planets and other objects while traveling at FTL and they are unable to change course enroute, also they can still see stars and other objects pass by while going at FTL which indicate they never leave our spacetime.

We have yet to see any Interdictor technology in Stargate neither have we seen any clues that it would be possible. In Star wars interdictor tech works by creating artificial gravity wells which shuts down hyperdrives as Star wars hyperdrives fails with catastrophic consequenses if they are active near gravity wells, in Stargate we have seen many examples of ships activating hyperdrives very close to huge gravity wells, the only thing we have seen that has an effect on a Stargate hyperdrive is a black hole, the space-time distortions causes changes in hyperspace and thus a hyperdrive can't activate.

So it could be possible with modification to the Asgard time dilation device to pull something out of hyperspace by collapsing the hyperspace field of the passing ship, or does the distortion simply stop the opening of the hyperspace window, and therefore such a technique would not work.

You did not understand what I said. I made an analogy between a wormhole created by a stargate and hyper space created with the help of a hyper drive. I will explain one more time. When a wormhole is dialled, the path for the traveller is predefined and cannot be altered. Going back to Teal'c, SGC cannot divert him manually to another planet whenever they please if he is on his way to Dakara. Hyper space is similar. Before Caldwell enters hyperspace to fly to Atlantis from Earth, the computer plots the route from beginning to end and opens the hyper space window. The fact that they can drop out of hyperspace and resume it whenever they please is just wrong . It is a SciFi cliché. When it comes to Hyperspace, in some aspects, Star Wars is more realistic. Many theories in Stargate are based on the work done by Hawkins. Need to understand more, read my previous post about hyper space and its levels.

And this is why crossover comparisons should be avoided at all costs - people get too easily confused.

Hyperdrive is much like warp drive in that a ship jumps out of conventional spacetime and enters subspace to travel. Once in subspace, the ship can travel in any direction and replot itself to a new course.

This is unlike wormhole travel, which creates a bend in space time that allows the user to be transported to the other side. We don't leave conventional space/time when we go in a wormhole. In Hyperspace, we do.

I don't think Trek's trajectory is calculated to avoid planets. I think it's calculated to avoid gravitational fields (generated by stars and big planets) that might alter the course.

I thought trek just speed you up. it creates a warp field but doesn't actually take you out of normal space. There is a general route that is plotted but you often hear of course corrections these would presumably be to avoid stars, planets and other obstacles.

They do enter subspace (hence the flash as the ship goes into warp). The strength of teh warp field determines how "fast" the ship is propelled in subspace. They've also shown a complete coruse change during warp, which would be impossible if what Integrabyte said was true.

I must agree with you. From what I know about Warp travel and Star Trek, the warp field encompassing the ship allows you to travel very fast in the current space time as opposed to using hyper space , different space time, depicted in Stargate Sg1.

They do enter subspace

Not exactly....it can be said that subspace enters our universe ...

A symmetric warp field is a subspace field strong enough to shield a ship from normal space in a way that it takes on the frame of reference of subspace, while the ship itself is still in normal space. In order to become a warp field, the subspace stress has to be more than 1 cochrane. At 1 cochrane the field created by the subspace coils in normal space is strong enough to cross the threshold to the first subspace layer. Vice versa, subspace begins to flow into normal space. This subspace begins to "fill" the spatial distortion shell surrounding the ship, effectively shielding it against our universe. The ship is still in our universe, but it can move as if it were in subspace. Only that a symmetric warp field itself does not move the ship. It necessitates either an additional engine to achieve propulsion or, more elegantly, the warp field has to be tuned to become asymmetric and thereby propulsive.

At the end of the day, flying in hyperspace or flying in current space time but using subspace as a reference frame, is very similar. Warp travel kind of brings the hyperspace window and hyperspace in our current space time .

Again, you're taking something out of another science fiction series and using it in Stargate, which makes absolutely no sense. Hyperspace in stargate takes the ship into subspace. stop using Star Trek physics/engines adn applying them on the Stargate universe.

I am not applying anything. I just stated a similar fact between them. They both rely on different reference frames than our own universe. Where am i using star trek physics in Stargate Sg1? I clearly explained how you misunderstood the " They do enter subspace" part and the difference between warp field and hyper space. The mere fact that at the end of my post I emphasized how similar both technologies are does not show that I am applying one tech to the other show and vice versa.

Not every one has a degree in astrophysics/aerospace. If you have one, then ignore these "FTL travel 101" posts (simple analogies so everyone can understand). Other people actually learn from this board. On top of that....I am doing my masters in aerospace and I know a bit of , lemme put it this way, "science"....

I thought the flash was the equivalent of the sonic boom when going past the speed as sound, as you pass the speed of light it flashes.

It is the warp field around the ship allowing the subspace level to access our universe. When it comes to the sonic boom and speed of sound things are different.

In terms of the physics your probably right but in terms of the reason for adding that visualization to the show it is probably more along the lines of what i said.

[Hooperman1990]

I think the closest Trek technology to hyperspace is the borg trans-warp conduit (probably not actuallly theirs but they use it most). As far as i understand that takes the ship through a subspace conduit and exits somewhere else in the galaxy, which is essentially what happens in SG hyperspace although in Trek it was never really explained as well.

Also, does anyone know about the jumping in Wing Commander? I think thats fastest (instantaneous as far as the film was concerned) but you nearly blew up every time because it relied on strong natural gravitational fields. If anyone can elaborate on this please do.

In Battlestar galactica (the new i've never seen the old one) the jumps in that are pretty much instantaneous as well, at least from the viewer's point of view.

[IcyNeko]

The Wing Commander jump varies. In the movie, the Akwende Jump System was shown to be similar to Battlestar Galactica's, where it was instantaneous. However, the movie wasn't shown to be canon at all. The Movie's Akwende Jump system needed to hit certain gravity wells in order to create a gravimetric anomaly, which propelled the ship into a "jump", which is similar to the FTL jump of a Battlestar. The only difference is that the Battlestar could jump whenever and wherever, but the Wing Commander ships had to have certain conditions JUST RIGHT.

In the games, the jump system was shown (in Wing Commander IV) to be kind of like Stargate's Hyperspace, where it still took time, and you could talk while you travelled, but it was a far shorter time than Stargate (you could talk to prep for what to do on jump exit, but you couldn't go for days in a jump field). Again, for optimal success, the ship would have to hit a jump point ( a gravimetric sweetspot). The ship would then generate an anti-graviton field which would open a wormhole to the area it wanted to go in.

The more anti-gravitons that were poured in, the bigger the wormhole (and the longer it would stay open). Jump-capable ships would also polarize their hull with anti-gravitons so that the ship could safely travel in jump-space. The more antigravitons were generated into the wormhole, the larger it could be (and thus it would be possible to jump an entire squadron of fighters with the carrier without having to land the squadron). This isn't used as general practice, however, since doing so produces a huge graviton signature on the otherside, and enemies patrolling the area can see a huge fleet coming before it actually arrives. So most ships land all their fighters and rig their system to generate just enough for single-vessel travel, thereby minimizing their graviton signature.

But the ships don't necessarily need a jump point to jump in the game. Without a known jump point, however, one can literally end up anywhere and runs a high risk of making a fatal jump. In WC2, TCS Concordia and her escort destroyer and cruiser made a "blind double jump", which meant it jumped twice from the area they reached. The first jump was at a jump point, but the second one was not. The result was that the Concordia jumped into the middle of an asteroid field and nearly was destroyed, and one of the other two ships either jumped into a planet or into a star.
