"There is a fifth force which shaped religious belief, but its effect is so universal and profound that it deserves to stand alone...it deserves to be written thus: SPACE TRAVEL!"

―unknown

Space travel played a major role in the evolution and expansion of humanity throughout the known universe. Two forms of space travel existed: faster than light space travel, and conventional space travel.

Faster than light travel

For several thousand years, faster than light travel (or space-folding) was conducted exclusively by the Spacing Guild, using Spacefolder vessels piloted by Guild navigators that folded space-time and moved almost immeasurable distances in the blink of the eye.

This form of travel, while extremely expensive, was also not safe as one in ten ships that used space folding engine disappeared, at least during the early years of the technology's use before the advent of Navigators. It was utilized for both commercial and military purposes. Space-folding made use of two key factors:

• The folding of space-time, which was accomplished by the practical application of the Holtzman Effect. ==References and notes==

• The plotting of a safe course through folded space by a Guild Navigator, who used prescient planning induced by vast amounts of the Spice Melange.

Conventional space travel

Conventional space travel was used mainly for travel within the confines of a star system (so not for interstellar travel). However, before the discovery of faster-than-light travel it was also used for long-distance space travel.

By the time faster-than-light travel had been discovered, conventional space travel had come relatively close to the speed of light, but this of course still required years to reach other stars.

Behind the Scenes

The connection between faster than light travel and the Holtzman Effect is not explicitly mentioned by Frank Herbert. It is a connection made in the prequel novels by Brian Herbert and Kevin J. Anderson.

In the 'Legends of Dune' trilogy, the pair describe the time shortly before and during the discovery of space-folding. In these works the discovery of space-folding is attributed to Norma Cenva, who goes on to become the first prescient folded space navigator. Prior to this, although described in 'The Machine Crusade' as "outracing the old faster than light method", vessels still took weeks or months to cross between even the closest stars.
