I'm wondering what technological means there are in Star Trek to go faster than warp 10.
To state the question more precisely: you can use a wormhole, a Q, a Traveller and so on to accomplish the same result (getting far away very fast). But those methods are somewhat "natural". Also I don't consider teleporting a mean to go faster than warp 10, because basically that's just disappearing at one place and instantaneously reappearing somewhere else.
What I'm actually looking for are technologies like Transwarp Coils, the displacement wave used by the Caretaker to bring Voyager to the Delta Quadrant, the Graviton Catapult... so I'm looking for technological inventions that let you fly real fast.
