Out of all the Space Scifi, Star Wars, is perhaps the worst when it comes to laws pf physics and everything else.
Yep. It is fine for soft SciFi to get around the limits of the speed of light by coming up with space folding, short cuts through other dimensions (think of two points at opposite ends of a sheet of paper and you fold the sheet so that they are touching), etc. However, in Starwars they refer to parsecs as a unit of time rather than distance and they make the jump to light speed not FLT as would be required to cover the vast distances.
while I do admit that there are some impossiblities in the Star Wars universe (freaking turbofan engines on the X-wing in a vacuum!) the main point we are debating is the likely plot device.
I'll say this in this thread too. Wookiepedia, while incredibly useful, cannot be fully trusted to be The Truth. Many, many things on it are pure conjecture made by fans. Treating it as the cold hard truth is foolish.
Sorry, just had to say that. Admittedly, hyperspace is sometimes talked about as though it is another dimension, many, many things about hyperspace are not consistant with that fact. For instance:
During the clone wars it's known that a Republic ship going at the speed of light impacted a planet and ripped it apart. And also contrary to popular belief, Katana Fleet didn't stay in hyperspace. Every time it's mentioned it's said to be 'constantly jumping around', and when Thrawn finally finds it, the Katana Fleet isn't in hyperspace, it's drifting out in the middle of space. But really, hyperspace probably isn't another universe. First off, a different universe can't explain the hyperspace cannons. For those of you not well versed in ancient star wars history, hyperspace cannons were just that. They literraly fired a ship into hyperspace. You can't fire something into an alternate reality. Also, gravity wells affect hyperspace wa-a-a-a-ay to much to be another universe. Gravity wells wouldn't extend to another universe, since the mass creating the well wouldn't exist in that other universe. Another thing i noticed, and this is pure conjecture, is that ships cannot see other ships even in the same fleet as them in hyperspace. Were hyperspace another universe, they should hypothetically be able to see any ship using the universe along with them. Going faster than light makes much more sense, because at those speeds other craft, even those the next to you would not be visible. Lightwaves would not have enough time to cross the distance, thus, the other ships would be for all intents and purposes, invisible. I've already mentioned the collision of a ship into a planet, which wouldn't happen if hyperspace was another universe. And the hyperspace disturbances outside the galaxy, which while being a plot dvice to keep everyone in, also fit the ftl theory. The movement and gravitic disturbance of a galaxy's rotation could screw up space around the arae, preventing ships from accelerating to fast. Plus, Outbound Flight was sent to use the force to calm the disturbances. Now how cold the force influence an alternate universe?
It's impossible to know the interaction of gravity in one universe on another universe. Think, if gravity could bleed over from other universes, why aren't there massive random gravitic anomlies all over the place as massive objects in other universes cause gravwells. It's too rediculous to say that every universe has the same number of celestial bodies in the same places, causing the same effects.
Those were all rehashed arguments from the SoaSE thread. Thought i'd post 'em here.
and to tell you the truth, I'm beginning to think that hyper is just outside our dimension - cloe enough to be affected by it, but far enough where it isn't part, technically. like the bent stick/sheet model - traveling along the surface of the stick/sheet is nowhere near as fast as bendin the stick and traveling straight through the space between the points. the space that isn't filled by the stick/sheet would be hyper and the stick/sheet would be realspace.
and the reason that there aren't gravitic disturbances is because chances are that the in the other universe, there are no galaxies on the same place occupied by our galaxy.
as for how the Force could affect another universe - simple, there happens to be Force there as well. another explanation - ITS THE FORCE!!!! The all powerful, the one true destiny, the alpha and omega. okay, maybe I went a little overboard there.
Star Wars takes place in our dimension and universe - in the very beginning it says "A long time ago, in a galaxy far, far away," not "A long time ago in another dimension or other universe"
