FTL travel is possible even with real world physics. What you would need to do is condense the fabic of space time in front of the ship ( this is basically what gravity does) and then expand the fabric of space time behind the ship ( this might be what dark energy does). The ship would remain in a normal space bubble. This way you wouldnt have to worry about Einsteins pesky relativity either. Alot of sci fi eludes to this idea of being in some sort of bubble or shield of normal space. 

actually, the star wars ones are "blasters", not lasers.  even ships batteries are reffered to as "turboblasters"

Except for the fact that a phase jump is a designated place and you cant use any other. Star Wars Hyperspace jumps can be made almost anywhere. thats why I have suggested a rts game designed in revolving Solar system where the phase lanes change and be more realistic.

EDIT: If you complete missed our debate of hyperspace its back in Saint of a Solar Empire post pages 10-12. Question do you want me to copy all the text debate to over here?

I do know they use the word blaster.  However, I am not sure on the turboblasters.  I need to look that up.  The only time I know for sure they use the word laser is with the deathstar.  And that thing does at least kind of work like one.

Edit:

It does not mean I am right, but so far I can only find blasters refearing to the small arms.  Lasers seems to be used for ships.  It was only a quick search throught a couple of books.

yes there are blasters as in the hand held gun, there is no such thing as a turboblaster, but there is a turbolaser.

hmmm.... you're right.  anyway, they aren't actual lasers either way - they are assumed to be superheated plasma projected and held together by a magnetic field from the barrel.

It's just faster than light drives. George Lucas settles this in a documentary I saw years ago (which I don't remember the name of) personally. He mentions how he had to set down some ground rules for the setting to work, for the setting to make "sense" (from a perspective of internal realism, obviously).

This includes things such as "In Star Wars, there is sound in space", as well as the fact that it's possible to travel faster than the speed of light, and the lack of time dilation. I believe those were the things brought up specificly (and I know for sure that "sound in space" was). But more importantly, it gives a view into the facts that Star Wars is it's own universe and it has it's own laws.

Okay lets go with that.

Back to the hyperspace, here is what I got from the force.net

Edit, I posted the link but this is what I picked up from it.

Hyperspace is not simply another realm, disconnected from the real universe. Every point and time in hyperspace is associated with a place and moment in realspace, and vice-versa. Hyperspace is not apart from realspace; instead it is an alternate aspect of the universe which is only experienced by objects moving faster than light.

I think I like that one, now the question is how do we get there?

Actually, Orodum, i kinda like that explantation. That hyperspace is another dimension that sort of overlaps with real space. It would explain all of the evidence that hyperspace is both is and isn't another dimension. That actually......might work!

And by the way, the 'sound in space' is explained. There actually isn't any sound, and what you hear is synthesized by each ship. I can't exactly remember where i read it, but i think it was in one of West End Games' sourcebooks.

Hyperspace is, so I believe, just a fancy name for wormholes. It even looks like a freakin' tunnel. Not that a wormhole would look like that, its just that we imagine them like tunnels. And it fits the bill. You travel irrespective of normal space-time laws as you are essentially travelling through a fifth dimension. But at the same time, space-time does affect you still in such ways as distance and gravity because a fifth dimension is still not an alternate universe.

Also, gravity does not affect hyperspace travel as such, it affects hyperdrives, as is referenced by the technology of hyperspace bubbles, used to "coast" through interdiction fields (basically artificial gravity wells) by inertia alone. This means that hyperdrives probably would use gravity to generate the hyperspace effect which also fits the wormhole theory.

And the big guns on the ships are called turbolasers, not turboblasters. Though, I don't know if this was mentioned, they *are* still blasters, they use Tibanna gas to generate plasma bolts, not laser beams.

One other possible explanation of hyperspace would be that a hyperdrive manipulates the mass signature of a ship to completely elliminate its mass and thus avoid hitting obstacles set by Einstein which stipulated that any object approaching the speed of light would have its mass increase exponentially into infinity, thus making it impossible to generate a thrust powerful enough to propel the ship over the light barrier. With no mass this would not be a problem, you could theoretically reach infinite speeds. Since Star Wars technology knows about gravity manipulation and inertia stabilization, this sort of thing might be possible. It would even explain the rapid acceleration and "drop-out" effects seen by Star Wars ships entering and exiting hyperspace. With no mass you can reach maximum speed (and reverse) in an instant.
