The Story of Everything: A Synopsis of The Urantia Book
Paper 49: The Inhabited Worlds
All worlds inhabited by mortals are evolutionary planets administered in systems of one thousand planets. Our system, Satania, is incomplete, with six hundred and nineteen inhabited worlds. Thirty-six more planets are near the life endowment stage, and nearly two hundred will be inhabitable within the next few million years.
Evolution may not always be predictable but it is never accidental. There is a precise system that determines the unfolding of life but no two worlds are exactly alike. Life Carriers have developed seven distinct physical types of mortal life.
Atmospheric types are divided into nonbreathers, subbreathers, mid-breathers and superbreathers. Mortals on the planet Venus would be superbreathers, and on Mars, subbreathers. If mortals lived on the moon they would be nonbreathers. In Nebadon, less than three percent of all planets are inhabited by nonbreathers. Such a sphere exists in close proximity to Earth.
Elemental types may dwell on land, in the treetops, in the water, or in the air.
Gravity types are modified to adapt to a planet's gravity pull. Mortals in Nebadon average seven feet in height, with a range between two and a half feet and ten feet tall.
Temperature types come in five orders according to the surface temperature of their world.
Electric types display ten various adjustments to electric, magnetic, and electronic energies.
Energizing types are categorized regarding nutritional intake.
Unnamed types have numerous additional unrevealed variations.
All will creatures are erect bipeds. There are three primary and three secondary races, but not all races are present on all planets. The average number of physical senses is twelve. Sex equality prevails on all advanced worlds. Agriculture is the one pursuit common to every atmospheric planet. Mortal longevity ranges from twenty-five years to nearly five hundred years.
Mortals may have different brain structures. The three-brained types are more spiritual, ethical, and worshipful than two-brained types such as Urantians, who are in turn more imaginative, adventurous, and philosophical than one-brained mortals. All three orders are equally qualified for the ascension career.
Spirit reception is influenced by mind design, specifically, by the organization of certain glands that produce differing chemical endowments. Mortal survival is dependent on the birth and evolution of the immortal soul. Some people attain sufficient spiritual progress during their mortal lives to forego mansion world training. These individuals experience the mansion world as teachers rather than students. Some mortals from advanced planets escape the world of their nativity by fusing with their Thought Adjusters. Natural death becomes increasingly infrequent on spheres long settled in light and life.
