Soundbust11 (Oh, also, you probably need to form the two ends of the wormhole really close together then transfer them to their position. If you achieved a great level of manipulation of space-time, then you can probably use a sort of warp drive (which also uses exotic matter, see alcubierre drive for more info) to carry the wormhole entrance and exit inside the bubble.)
(You also probably need an extremely large ship if you want a big wormhole. Say, a few kilometers across and long?)
