  If you actually move the gravity well, you would presumably have to
put a lot of energy into it - and presumably lose all the momentum you
got from it.  I guess if you destroyed it and created a new one that
might be better.  Of course we're talking fiction so whatever makes
for better movie special effects is what you'd use.
