The Andromedans have a lot of technologies that require bending/expanding the space continuim.
The displacement device (DisDev) removes a ship from the known boundaries/limits of "our" space and returns it instantly to "our" realm up to 120,000km from where it was.
The rapid transit network (RTN) allows for moving distances that, by normal warp technology, would require speeds of warp factor 15. Remember that warp 15 is not 15 times the speed of light. Warp 1 is the speed of light (1 to the 1st power) warp 3 is 9 times the speed of light (3 to the 3rd power) warp 15 is 3,269,017 times the speed of light (If I did my math right.
).
The temporal elevator (TE) has the effect of moving an object in a 4th dimensional direction without it ever leaving 3 dimensional space. For me, since I don't understand movement beyond 3D, the best description for this is to imagine the 2D playing map for SFB. The TE would move a base "up" from 1 to 10 hexes. (Andromedans can control the "height" of the elevator.) above the map. The rest of the players would only have the ability to maneuver in the 2D "world" while the Andromedan can use to a limited degree the 3rd dimension.
The hangers having a volume that is greater than the overall size of the mother ship is another capability of this technology.
