What would this advanced technology be? The most they would do is have vessels that go faster than the speed of light. Whee, they can travel an unremarkably infinitesmal distance across the universe faster than us. Or have they tapped into wormholes or some other such stuff?

Why would they even need technology? Would their technology be formed from, say, tapping into the atomical structure of water and shaping it to your will? Who fucking knows, there is no point in speculating until something comes of it.
