Quite true.

The universe has no "clock" as far as we know. Besides, giving structure
to the fabric of space would only strenghten FTL (Try walking in a
vacuum). It gives you something to warp (Alcubierre's theory),
somethingto push against (the Aether hypothesis), and alot of energy.
Lee Parker is right though: it could be used badly. So lets use it for
good (FTL Propulsion), not planet bombs.
