Editing Spaceship (section)

===Spaceships in [[Dune]]===
One of the granddaddies of Sci-Fi, Dune is where the concept of the Navigator is shamelessly ripped off from. In this setting, Navigators are humans of the Spacing Guild, who have been sufficiently mutated by a drug called Spice that they cease to be human at all; their consciousness has been expanded to such a degree that they now have limited precognition, and use it to determine the vector for their destination. They then fold spacetime to be able to cross the galaxy faster than the speed of light. While it is possible to build a computer that can also navigate across space, such computers have been forbidden since the Butlerian Jihad against thinking machines.
