Editing The Urantia Book (section)

=== Cosmology ===
The book describes that at the center of the cosmos is the stationary Isle of Paradise—the dwelling place of [[God]]—with Paradise being surrounded by "Havona," an eternal universe containing a billion perfect worlds, around which seven incomplete and evolutionary "superuniverses" circle.{{sfn|Gardner|1995|p=12}}{{sfn|Lewis|2003|p=140}}

The word "universe" in the book is used to denote a number of different scales of organization.  A "superuniverse" is roughly the size of a [[galaxy]] or group of galaxies, and the seven superuniverses along with Paradise-Havona are together designated as the "grand universe." A "local universe" is a portion of a superuniverse, with 100,000 local universes being in each superuniverse.{{sfn|Gardner|1995|p=12}}  Beyond the seven superuniverses, uninhabited "outer space levels" are described.  The term "master universe" refers to what in modern usage would be the total universe—all existing [[matter]] and space taken as a whole.

Urantia is said to be located in a remote local universe named "Nebadon," which itself is part of superuniverse number seven, "Orvonton." The physical size of a local universe is not directly stated, but each is said to have up to 10 million inhabited worlds.{{sfn|Gardner|1995|p=12}}
