Reaction drive: Difference between revisions

{{Era|Forerunner}}

'''Reaction drives''' were a form of spacecraft propulsion used by the [[Forerunner]]s. Little is known about them other than the fact that they use [[vacuum energy]] to expel virtual neutrons from the ship. During their momentary existence, the virtual particles give the ship propulsion, then disappear.<ref>'''[[Halo: Cryptum]]''', Chapter 12, ''page 129''</ref> They do require a form of on-board fuel and reaction mass to operate, however.<ref> '''Halo: Cryptum''', Chapter 12, ''page 124''</ref>
