2. ORGANIZATION OF THE SUPERUNIVERSES
15:2.1 Only the Universal Father knows the location and actual number of inhabited worlds in space; he calls them all by name and number. I can give only the approximate number of inhabited or inhabitable planets, for some local universes have more worlds suitable for intelligent life than others. Nor have all projected local universes been organized. Therefore the estimates which I offer are solely for the purpose of affording some idea of the immensity of the material creation.
15:2.2 ¶ There are seven superuniverses in the grand universe, and they are constituted approximately as follows:
15:2.3 1.
15:2.4 2.
15:2.5 3.
15:2.6 4.
15:2.7 5.
15:2.8 6.
15:2.9 7.
15:2.10 ¶ Excluding the Paradise-Havona spheres, the plan of universe organization provides for the following units:
15:2.11 Superuniverses: 7
15:2.12 Major sectors: 70
15:2.13 Minor sectors: 7?103
15:2.14 Local universes: 7?105
15:2.15 Constellations: 7?107
15:2.16 Local systems: 7?109
15:2.17 Inhabitable planets: 7?1012
15:2.18 Each of the seven superuniverses is constituted, approximately, as follows:
15:2.19 One system embraces, approximately 103 worlds
15:2.20 One constellation (100 systems) 105 worlds
15:2.21 One universe (100 constellations) 107 worlds
15:2.22 One minor sector (100 universes) 109 worlds
15:2.23 One major sector (100 minor sectors) 1011 worlds
15:2.24 One superuniverse (10 major sectors) 1012 worlds
15:2.25 ¶ All such estimates are approximations at best, for new systems are constantly evolving while other organizations are temporarily passing out of material existence.
3. THE SUPERUNIVERSE OF ORVONTON
15:3.1 Practically all of the starry realms visible to the naked eye on Urantia belong to the seventh section of the grand universe, the superuniverse of Orvonton. The vast Milky Way starry system represents the central nucleus of Orvonton, being largely beyond the borders of your local universe. This great aggregation of suns, dark islands of space, double stars, globular clusters, star clouds, spiral and other nebulae, together with myriads of individual planets, forms a watchlike, elongated-circular grouping of about 1/7th of the inhabited evolutionary universes.
15:3.2 From the astronomical position of Urantia, as you look through the cross section of near-by systems to the great Milky Way, you observe that the spheres of Orvonton are travelling in a vast elongated plane, the breadth being far greater than the thickness and the length far greater than the breadth.
15:3.3 Observation of the so-called Milky Way discloses the comparative increase in Orvonton stellar density when the heavens are viewed in one direction, while on either side the density diminishes; the number of stars and other spheres decreases away from the chief plane of our material superuniverse. When the angle of observation is propitious, gazing through the main body of this realm of maximum density, you are looking toward the residential universe and the centre of all things.
15:3.4 ¶ Of the ten major divisions of Orvonton, eight have been roughly identified by Urantian astronomers. The other two are difficult of separate recognition because you are obliged to view these phenomena from the inside. If you could look upon the superuniverse of Orvonton from a position far-distant in space, you would immediately recognize the ten major sectors of the seventh galaxy.
15:3.5 The rotational centre of your minor sector is situated far away in the enormous and dense star cloud of Sagittarius, around which your local universe and its associated creations all move, and from opposite sides of the vast Sagittarius subgalactic system you may observe two great streams of star clouds emerging in stupendous stellar coils.
15:3.6 The nucleus of the physical system to which your sun and its associated planets belong is the centre of the onetime Andronover nebula. This former spiral nebula was slightly distorted by the gravity disruptions associated with the events which were attendant upon the birth of your solar system, and which were occasioned by the near approach of a large neighbouring nebula. This near collision changed Andronover into a somewhat globular aggregation but did not wholly destroy the two-way procession of the suns and their associated physical groups. Your solar system now occupies a fairly central position in one of the arms of this distorted spiral, situated about halfway from the centre out towards the edge of the star stream.
15:3.7 ¶ The Sagittarius sector and all other sectors and divisions of Orvonton are in rotation around Uversa, and some of the confusion of Urantian star observers arises out of the illusions and relative distortions produced by the following multiple revolutionary movements:
15:3.8 1. The revolution of Urantia around its sun.
15:3.9 2. The circuit of your solar system about the nucleus of the former Andronover nebula.
15:3.10 3. The rotation of the Andronover stellar family and the associated clusters about the composite rotation-gravity centre of the star cloud of Nebadon.
