Idle response: physics as we know it make using metal bricks to travel between star systems vanishingly unlikely. It's way too costly in terms of both energy/materials and time. What I believe "wrap speed" technology will turn out to be, as well as the truth about the nature of life and ultimately our civilization, is that ancestral intelligence forms have learned to use much more ephemeral expressions capable of harnessing quantum entaglement-like interaction to travel and manipulate reality. Getting even more outlandish: I think this solves Fermi paradox as well as the enigma of how fast hunter-gatherer apes suddenly went from farming villages to orbital stations. We are a colony of such beings into more hoarse matter. They found an ecosystem, and figured out a way to inject people into it as a way to maybe imprison and/or re-educate unruly types. And now our material techniques have advanced far enough that we can actually begin to detect some of their activities.
