Hehe, I think its normal in space that you don't think your moving when ur moving. Why? Because your movespeed is soooo low compared to the extreme size of space and pretty all objects in it, that you just don't get a noticeable effect in a short time (unless you move at some speed much higher than light-speed, which is I think what in star trek is/must be the case, or you would never get these light distortions (lines expanding from the center)).
Look for example at these data:

edit: this is when travelling with light-speed (which is the theoretical maximum speed in our universe)
Earth to moon 1 second
Earth to sun 500 seconds (8 min.)
Sun to Mars 12.5 minutes
Sun to Jupiter 40 minutes
Sun to Pluto 5.5 hours
Solar system diameter (at orbit of Pluto) 11 hours
Sun to nearest star 4 years
Sun to center of galaxy 30,000 years
Diameter of galaxy 100,000 years
Distance of Andromeda galaxy 2 million years
Distance to "edge" of universe 15 billion years
As I dont think your simulator allows this high speed travels, I suggest something different:
You can give a sensation of moving if you let the camera behind when giving more speed (requires external ship view), you know, by changing the distance of camera and ship you can notice movement.
You can furthermore draw variable gas emission (which is realistic anyways, unless your ship moves with some fictive engine that does not work on the actio = reactio principle...)...
I would only do the light effect when traveling at a very high speed as in star trek (altough its still unrealistic if you look at the time table
)
But in the end its your simulator and you can do whatever you want / like
This was just what popped into my mind when I read this.
