It would be fantastic if warp drives were possible, but they must not be available because we are not currently being over run by alien visitors.

The Alcubierre warp drive is then important as a gadget, along with wormholes as related things, to understand how nature prevents closed timelike curves and related processes." (Six votes.) This quote reminds me of the transport ships in Dune with the navigators that David Lynch renders like whales: "Relativistic effects happen when you travel near light speed through space-time. With the Alcubierre drive, you don't travel through space-time, but remain stationary and the space-time around you is warped in a way that brings you closer to your destination. So if it only took a week for you, it would only take a week for your observers." (Two votes.)
