Well first let me state my caveat. There is a difference between proven science and theory.
M-Theory states our universe, and all spacetime as we know it exists on a membrane shaped slice. In this way we could be very close physically speaking to another such membrane. In this regard we and all of spacetime would be bound to this membrance.
You should watch the entire nova presentation on string theory but this episode relates to the brane, or membrane that we may very well call home to our universe.

Which if true would mean that we could move as it relates to other branes.
But again other than bending, stretching and compressing as the previous poster stated this is the only theory stating anything else of interest about moving space unless you look at a quantum level where spacetime is violent and ever changing not sure how real physcists would explain it but from what I have read it sounds like spacetime would move to acomlish these quantum fluctionations.
I dont know im just rambling now hehe.
1st post btw, great community you have here! ; - )
