hm, as far as I understood your problem, physics don't work without a Sky-Cube but you need them. Well, even if you are going to make a space shooter, you *WILL* need a Sky-Cube in order to display all the stars in the background. And if you don't want to do that, simply paint the cube all black - it will make your physics work properly and won't cause you any trouble. Besides you may change the level if the spaceship touches the Cube which will make it easier to calculate when the level has to be changed - as said, that's the way I understood your problem.


Greetz!
