A Generation Ship is a spacecraft constructed to travel across the immense distances of interstellar space by large ships capable of carrying populations which live aboard for at least one and perhaps several human generations. First suggested either by John Bernal or by Konstantin Tsiolkovsky - ownership appears disputed - the idea has appeared many times in science fiction novels. Among the major alternatives to generation ships are space ships that travel close to the speed of light to exploit the time dilation effect, space ships which carry passengers in suspended animation, and hyperspace drives that exploit as yet unknown physics and undeveloped engineering.
