What happens when a species' homeworld becomes uninhabitable? Simply pack everything up and leave.

In fiction, this generally (sometimes unintentionally) serves one of two purposes:

  • It's a way to take the homeworld out of the story. If your story is about humans flying through the galaxy looking for a place to settle, then take Earth out of the picture.
  • It justifies massive culture changes. With no ideological baggage, the species is free to change in any way the creator wants.
Examples of Homeworld Evacuation include:

Comic Books

  • In some Marvel Comics stories, inhabited planets have a Galactus protocol which is essentially this.
  • It's a staple of the Superman mythos that Jor-El wanted this to happen but, for whatever reason, was rejected. He only managed to launch an experimental pod containing his infant son.
  • Discussed but never actually occurs in several Star Trek comics.
  • Up to Eleven in the old Star Wars Expanded Universe where the Yuuzhan Vong fled their galaxy due to a machine uprising and a series of wars.
  • Happens three times in Transformers: Unicron. First when Unicron devours Elonia, Space Bridge technology is used to evacuate 3/4ths of the population. When Unicron eats Caminus, the natives flee via Space Bridge. And when Cybertron is ripped to shreds, the Spectral Knights use their magic to teleport everyone off the planet and to Earth.
  • An unusual example occurs in the Valerian story, Welcome to Alflolol. The uninhabited Death World of Technorog is a mining colony for the Terran Galactic Empire only for it to be revealed that the long-lived inhabitants merely took a 4,000 year holiday. In the end, the natives decide to leave the planet rather than be bound by Earth's binding rules and regulations. The whole thing was an allegory for the treatment of Native Americans under the rule of Western colonizers.
