Humans are thought to be able to live only in four dimensions.

In "Interstellar" neighborhood of gas giant Saturn, with the most complex and largest ring system in the Solar System, is favored for colonies on Edmunds’, Mann’s, and Miller’s exoplanets and stations.

Wormhole travel could occur much closer to home: As travelable shortcuts, wormholes may connect not only two universes but also two distant regions in the same universe.
