AbstractThe possibilities of interstellar flights for extraterrestrial civilizations have been considered. A superluminal motion (hypermotion) via M. Alcubierre's warp drive is considered. Parameters of the warp drive have been estimated. The equations of starship geodesics have been solved. The starship velocity has been shown to exceed the speed of light, with the local velocity relative to the deformed space-time being subluminal. Hawking's radiation does not prove to affect the ship interior considerably. Difficulties related to a practical realization of the hypermotion are indicated.
HighlightsSuperluminal velocities of the starship are possible due to space-time deformation.It takes a few days to reach Proxima Centauri via Alcubierre's warp drive.The warp drive creation by a supercivilization requires a galactic energy consumption.
