It's not moving the universe.... you jsut have 3 coords od ship x y z, supose 30*30*30 bxes compound the universe sized 10000,10000,10000 so you just load 27 pivots each one with a small distance between them and your ship.
distance to objecto woudl be signed distance ship-pivot + signed distance pivot-object.
dividing the universe into sveral minr pieces coudl give you 3 more decimals per dimension (1000,1000,1000 divisions subspace) whicih I think is what you are missing by using regular numbers.
