1:0.2The myriads of planetary systems were all made to be eventually inhabited by many different types of intelligent creatures, beings who could know God, receive the divine affection, and love him in return. The universe of universes is the work of God and the dwelling place of his diverse creatures. “God created the heavens and formed the earth; he established the universe and created this world not in vain; he formed it to be inhabited.”
1:5.3God is not hiding from any of his creatures. He is unapproachable to so many orders of beings only because he “dwells in a light which no material creature can approach.” The immensity and grandeur of the divine personality is beyond the grasp of the unperfected mind of evolutionary mortals. He “measures the waters in the hollow of his hand, measures a universe with the span of his hand. It is he who sits on the circle of the earth, who stretches out the heavens as a curtain and spreads them out as a universe to dwell in.” “Lift up your eyes on high and behold who has created all these things, who brings out their worlds by number and calls them all by their names”; and so it is true that “the invisible things of God are partially understood by the things which are made.” Today, and as you are, you must discern the invisible Maker through his manifold and diverse creation, as well as through the revelation and ministration of his Sons and their numerous subordinates.
3:3.1“God knows all things.” The divine mind is conscious of, and conversant with, the thought of all creation. His knowledge of events is universal and perfect. The divine entities going out from him are a part of him; he who “balances the clouds” is also “perfect in knowledge.” “The eyes of the Lord are in every place.” Said your great teacher of the insignificant sparrow, “One of them shall not fall to the ground without my Father’s knowledge,” and also, “The very hairs of your head are numbered.” “He tells the number of the stars; he calls them all by their names.”
3:3.2The Universal Father is the only personality in all the universe who does actually know the number of the stars and planets of space. All the worlds of every universe are constantly within the consciousness of God. He also says: “I have surely seen the affliction of my people, I have heard their cry, and I know their sorrows.” For “the Lord looks from heaven; he beholds all the sons of men; from the place of his habitation he looks upon all the inhabitants of the earth.” Every creature child may truly say: “He knows the way I take, and when he has tried me, I shall come forth as gold.” “God knows our downsittings and our uprisings; he understands our thoughts afar off and is acquainted with all our ways.” “All things are naked and open to the eyes of him with whom we have to do.” And it should be a real comfort to every human being to understand that “he knows your frame; he remembers that you are dust.” Jesus, speaking of the living God, said, “Your Father knows what you have need of even before you ask him.”
11:0.1Paradise is the eternal center of the universe of universes and the abiding place of the Universal Father, the Eternal Son, the Infinite Spirit, and their divine co-ordinates and associates. This central Isle is the most gigantic organized body of cosmic reality in all the master universe. Paradise is a material sphere as well as a spiritual abode. All of the intelligent creation of the Universal Father is domiciled on material abodes; hence must the absolute controlling center also be material, literal. And again it should be reiterated that spirit things and spiritual beings are real.
12:8.1“God is spirit,” but Paradise is not. The material universe is always the arena wherein take place all spiritual activities; spirit beings and spirit ascenders live and work on physical spheres of material reality.
14:2.1Spirit beings do not dwell in nebulous space; they do not inhabit ethereal worlds; they are domiciled on actual spheres of a material nature, worlds just as real as those on which mortals live. The Havona worlds are actual and literal, albeit their literal substance differs from the material organization of the planets of the seven superuniverses.
14:3.6The planetary construction of the Havona spheres is entirely unlike that of the evolutionary worlds and systems of space. Nowhere else in all the grand universe is it convenient to utilize such enormous spheres as inhabited worlds. Triata physical constitution, coupled with the balancing effect of the immense dark gravity bodies, makes it possible so perfectly to equalize the physical forces and so exquisitely to balance the various attractions of this tremendous creation. Antigravity is also employed in the organization of the material functions and the spiritual activities of these enormous worlds.
14:4.11The natives of Havona live on the billion spheres of the central universe in the same sense that other orders of permanent citizenship dwell on their respective spheres of nativity. As the material order of sonship carries on the material, intellectual, and spiritual economy of a billion local systems in a superuniverse, so, in a larger sense, do the Havona natives live and function on the billion worlds of the central universe. You might possibly regard these Havoners as material creatures in the sense that the word “material” could be expanded to describe the physical realities of the divine universe.
15:2.31. The System. The basic unit of the supergovernment consists of about one thousand inhabited or inhabitable worlds. Blazing suns, cold worlds, planets too near the hot suns, and other spheres not suitable for creature habitation are not included in this group. These one thousand worlds adapted to support life are called a system, but in the younger systems only a comparatively small number of these worlds may be inhabited. Each inhabited planet is presided over by a Planetary Prince, and each local system has an architectural sphere as its headquarters and is ruled by a System Sovereign.
15:5.53. Gravity-explosion Planets. When a sun is born of a spiral or of a barred nebula, not infrequently it is thrown out a considerable distance. Such a sun is highly gaseous, and subsequently, after it has somewhat cooled and condensed, it may chance to swing near some enormous mass of matter, a gigantic sun or a dark island of space. Such an approach may not be near enough to result in collision but still near enough to allow the gravity pull of the greater body to start tidal convulsions in the lesser, thus initiating a series of tidal upheavals which occur simultaneously on opposite sides of the convulsed sun. At their height these explosive eruptions produce a series of varying-sized aggregations of matter which may be projected beyond the gravity-reclamation zone of the erupting sun, thus becoming stabilized in orbits of their own around one of the two bodies concerned in this episode. Later on the larger collections of matter unite and gradually draw the smaller bodies to themselves. In this way many of the solid planets of the lesser systems are brought into existence. Your own solar system had just such an origin.
15:5.64. Centrifugal Planetary Daughters. Enormous suns, when in certain stages of development, and if their revolutionary rate greatly accelerates, begin to throw off large quantities of matter which may subsequently be assembled to form small worlds that continue to encircle the parent sun.
15:5.75. Gravity-deficiency Spheres. There is a critical limit to the size of individual stars. When a sun reaches this limit, unless it slows down in revolutionary rate, it is doomed to split; sun fission occurs, and a new double star of this variety is born. Numerous small planets may be subsequently formed as a by-product of this gigantic disruption.

15:5.86. Contractural Stars. In the smaller systems the largest outer planet sometimes draws to itself its neighboring worlds, while those planets near the sun begin their terminal plunge. With your solar system, such an end would mean that the four inner planets would be claimed by the sun, while the major planet, Jupiter, would be greatly enlarged by capturing the remaining worlds. Such an end of a solar system would result in the production of two adjacent but unequal suns, one type of double star formation. Such catastrophes are infrequent except out on the fringe of the superuniverse starry aggregations.
15:5.97. Cumulative Spheres. From the vast quantity of matter circulating in space, small planets may slowly accumulate. They grow by meteoric accretion and by minor collisions. In certain sectors of space, conditions favor such forms of planetary birth. Many an inhabited world has had such an origin.
15:5.10–11 · two paragraphs not cited here ·
15:5.10Some of the dense dark islands are the direct result of the accretions of transmuting energy in space. Another group of these dark islands have come into being by the accumulation of enormous quantities of cold matter, mere fragments and meteors, circulating through space. Such aggregations of matter have never been hot and, except for density, are in composition very similar to Urantia.
15:5.118. Burned-out Suns. Some of the dark islands of space are burned-out isolated suns, all available space-energy having been emitted. The organized units of matter approximate full condensation, virtual complete consolidation; and it requires ages upon ages for such enormous masses of highly condensed matter to be recharged in the circuits of space and thus to be prepared for new cycles of universe function following a collision or some equally revivifying cosmic happening.
15:5.129. Collisional Spheres. In those regions of thicker clustering, collisions are not uncommon. Such an astronomic readjustment is accompanied by tremendous energy changes and matter transmutations. Collisions involving dead suns are peculiarly influential in creating widespread energy fluctuations. Collisional debris often constitutes the material nucleuses for the subsequent formation of planetary bodies adapted to mortal habitation.

15:6.14The Planets. These are the larger aggregations of matter which follow an orbit around a sun or some other space body; they range in size from planetesimals to enormous gaseous, liquid, or solid spheres. The cold worlds which have been built up by the assemblage of floating space material, when they happen to be in proper relation to a near-by sun, are the more ideal planets to harbor intelligent inhabitants. The dead suns are not, as a rule, suited to life; they are usually too far away from a living, blazing sun, and further, they are altogether too massive; gravity is tremendous at the surface.
15:6.15In your superuniverse not one cool planet in forty is habitable by beings of your order. And, of course, the superheated suns and the frigid outlying worlds are unfit to harbor higher life. In your solar system only three planets are at present suited to harbor life. Urantia, in size, density, and location, is in many respects ideal for human habitation.
15:6.16The laws of physical-energy behavior are basically universal, but local influences have much to do with the physical conditions which prevail on individual planets and in local systems. An almost endless variety of creature life and other living manifestations characterizes the countless worlds of space. There are, however, certain points of similarity in a group of worlds associated in a given system, while there also is a universe pattern of intelligent life. There are physical relationships among those planetary systems which belong to the same physical circuit, and which closely follow each other in the endless swing around the circle of universes.
20:5.4During the course of the long history of an inhabited planet, many dispensational adjudications will take place, and more than one magisterial mission may occur, but ordinarily only once will a bestowal Son serve on the sphere. It is only required that each inhabited world have one bestowal Son come to live the full mortal life from birth to death. Sooner or later, regardless of spiritual status, every mortal-inhabited world is destined to become host to a Magisterial Son on a bestowal mission except the one planet in each local universe whereon a Creator Son elects to make his mortal bestowal.
23:2.20They go forth to investigate the clues furnished by the space contemplators of the realms. Undoubtedly the Paradise Deities know of the existence of these undiscovered energy systems of space, but they never divulge such information. If the Solitary Messengers did not explore and chart these newly organizing energy centers, such phenomena would long remain unnoticed even by the intelligences of adjacent realms. Solitary Messengers, as a class, are highly sensitive to gravity; accordingly they can sometimes detect the probable presence of very small dark planets, the very worlds which are best adapted to life experiments.
29:2.186. System Centers. One Supreme Power Center is permanently assigned to each local system. These system centers dispatch the power circuits to the inhabited worlds of time and space. They co-ordinate the activities of the subordinate physical controllers and otherwise function to insure the satisfactory distribution of power in the local system. The circuit relay between the planets depends upon the perfect co-ordination of certain material energies and upon the efficient regulation of physical power.
29:4.24These transformers are powerful and effective living switches, being able to dispose themselves for or against a given power disposition or directionization. They are also skillful in their efforts to insulate the planets against the powerful energy streams passing between gigantic planetary and starry neighbors. Their energy-transmutive attributes render them most serviceable in the important task of maintaining universal energy balance, or power equilibrium. At one time they seem to consume or store energy; at other times they appear to exude or liberate energy. The transformers are able to increase or to diminish the “storage-battery” potential of the living and dead energies of their respective realms. But they deal only with physical and semimaterial energies, they do not directly function in the domain of life, neither do they change the forms of living beings.
32:2.7And now that the right-hand helper and chief executive of the Creator Son has been provided, there ensues the bringing into existence of a vast and wonderful array of diverse creatures. The sons and daughters of the local universe are forthcoming, and soon thereafter the government of such a creation is provided, extending from the supreme councils of the universe to the fathers of the constellations and the sovereigns of the local systems—the aggregations of those worlds which are designed subsequently to become the homes of the varied mortal races of will creatures; and each of these worlds will be presided over by a Planetary Prince.
32:3.2The physical systems of time and space are all evolutionary in origin. They are not even physically stabilized until they are swung into the settled circuits of their superuniverses. Neither is a local universe settled in light and life until its physical possibilities of expansion and development have been exhausted, and until the spiritual status of all its inhabited worlds has been forever settled and stabilized.
39:4.155. The Transporters. These are the transport seraphim who function in the local systems. In Satania, your system, they carry passengers back and forth from Jerusem and otherwise serve as interplanetary transporters. Seldom does a day pass in which a transport seraphim of Satania does not deposit some student visitor or some other traveler of spirit or semispirit nature on the shores of Urantia. These very space traversers will sometime carry you to and from the various worlds of the system headquarters group, and when you have finished the Jerusem assignment, they will carry you forward to Edentia. But under no circumstances will they carry you backward to the world of human origin. A mortal never returns to his native planet during the dispensation of his temporal existence, and if he should return during a subsequent dispensation, he would be escorted by a transport seraphim of the universe headquarters group.
40:9.5Such children of the local universe are enabled to repossess themselves of much of their former human memory experience through having it retold by the associated seraphim and cherubim and by consulting the records of the mortal career filed by the recording angels. This they can do with undoubted assurance because the surviving soul, of experiential origin in the material and mortal life, while having no memory of mortal events, does have a residual experiential-recognition-response to these unremembered events of past experience.
41:10.1Some of the variable stars, in or near the state of maximum pulsation, are in process of giving origin to subsidiary systems, many of which will eventually be much like your own sun and its revolving planets. Your sun was in just such a state of mighty pulsation when the massive Angona system swung into near approach, and the outer surface of the sun began to erupt veritable streams—continuous sheets—of matter. This kept up with ever-increasing violence until nearest apposition, when the limits of solar cohesion were reached and a vast pinnacle of matter, the ancestor of the solar system, was disgorged. In similar circumstances the closest approach of the attracting body sometimes draws off whole planets, even a quarter or third of a sun. These major extrusions form certain peculiar cloud-bound types of worlds, spheres much like Jupiter and Saturn.
41:10.2The majority of solar systems, however, had an origin entirely different from yours, and this is true even of those which were produced by gravity-tidal technique. But no matter what technique of world building obtains, gravity always produces the solar system type of creation; that is, a central sun or dark island with planets, satellites, subsatellites, and meteors.

- origins › molten-split
- suitability for life › water and air on gas-contraction and solid-accretion p. in earlier life, if not too small
41:10.3The physical aspects of the individual worlds are largely determined by mode of origin, astronomical situation, and physical environment. Age, size, rate of revolution, and velocity through space are also determining factors. Both the gas-contraction and the solid-accretion worlds are characterized by mountains and, during their earlier life, when not too small, by water and air. The molten-split and collisional worlds are sometimes without extensive mountain ranges.
41:10.4During the earlier ages of all these new worlds, earthquakes are frequent, and they are all characterized by great physical disturbances; especially is this true of the gas-contraction spheres, the worlds born of the immense nebular rings which are left behind in the wake of the early condensation and contraction of certain individual suns. Planets having a dual origin like Urantia pass through a less violent and stormy youthful career. Even so, your world experienced an early phase of mighty upheavals, characterized by volcanoes, earthquakes, floods, and terrific storms.
41:10.5Urantia is comparatively isolated on the outskirts of Satania, your solar system, with one exception, being the farthest removed from Jerusem, while Satania itself is next to the outermost system of Norlatiadek, and this constellation is now traversing the outer fringe of Nebadon. You were truly among the least of all creation until Michael’s bestowal elevated your planet to a position of honor and great universe interest. Sometimes the last is first, while truly the least becomes greatest.
41:10.6[Presented by an Archangel in collaboration with the Chief of Nebadon Power Centers.]

49:0.1All mortal-inhabited worlds are evolutionary in origin and nature. These spheres are the spawning ground, the evolutionary cradle, of the mortal races of time and space. Each unit of the ascendant life is a veritable training school for the stage of existence just ahead, and this is true of every stage of man’s progressive Paradise ascent; just as true of the initial mortal experience on an evolutionary planet as of the final universe headquarters school of the Melchizedeks, a school which is not attended by ascending mortals until just before their translation to the regime of the superuniverse and the attainment of first-stage spirit existence.
49:0.2–3 · two paragraphs not cited here ·
49:0.2All inhabited worlds are basically grouped for celestial administration into the local systems, and each of these local systems is limited to about one thousand evolutionary worlds. This limitation is by the decree of the Ancients of Days, and it pertains to actual evolutionary planets whereon mortals of survival status are living. Neither worlds finally settled in light and life nor planets in the prehuman stage of life development are reckoned in this group.
49:0.3Satania itself is an unfinished system containing only 619 inhabited worlds. Such planets are numbered serially in accordance with their registration as inhabited worlds, as worlds inhabited by will creatures. Thus was Urantia given the number 606 of Satania, meaning the 606th world in this local system on which the long evolutionary life process culminated in the appearance of human beings. There are thirty-six uninhabited planets nearing the life-endowment stage, and several are now being made ready for the Life Carriers. There are nearly two hundred spheres which are evolving so as to be ready for life implantation within the next few million years.
49:0.4Not all planets are suited to harbor mortal life. Small ones having a high rate of axial revolution are wholly unsuited for life habitats. In several of the physical systems of Satania the planets revolving around the central sun are too large for habitation, their great mass occasioning oppressive gravity. Many of these enormous spheres have satellites, sometimes a half dozen or more, and these moons are often in size very near that of Urantia, so that they are almost ideal for habitation.
49:1.3All the worlds of a local system disclose unmistakable physical kinship; nevertheless, each planet has its own scale of life, no two worlds being exactly alike in plant and animal endowment. These planetary variations in the system life types result from the decisions of the Life Carriers. But these beings are neither capricious nor whimsical; the universes are conducted in accordance with law and order. The laws of Nebadon are the divine mandates of Salvington, and the evolutionary order of life in Satania is in consonance with the evolutionary pattern of Nebadon.
49:1.4Evolution is the rule of human development, but the process itself varies greatly on different worlds. Life is sometimes initiated in one center, sometimes in three, as it was on Urantia. On the atmospheric worlds it usually has a marine origin, but not always; much depends on the physical status of a planet. The Life Carriers have great latitude in their function of life initiation.
50:0.2The signal for a System Sovereign to act in the matter of assigning a ruler to a given planet is the reception of a request from the Life Carriers for the dispatch of an administrative head to function on this planet whereon they have established life and developed intelligent evolutionary beings. All planets which are inhabited by evolutionary mortal creatures have assigned to them a planetary ruler of this order of sonship.
51:2.3While there is this dematerializing technique for preparing the Adams for transit from Jerusem to the evolutionary worlds, there is no equivalent method for taking them away from such worlds unless the entire planet is to be emptied, in which event emergency installation of the dematerialization technique is made for the entire salvable population. If some physical catastrophe should doom the planetary residence of an evolving race, the Melchizedeks and the Life Carriers would install the technique of dematerialization for all survivors, and by seraphic transport these beings would be carried away to the new world prepared for their continuing existence. The evolution of a human race, once initiated on a world of space, must proceed quite independently of the physical survival of that planet, but during the evolutionary ages it is not otherwise intended that a Planetary Adam or Eve shall leave their chosen world.
55:0.3Only those planets which attain existence in the main circuits of the superuniverse are assured of continuous survival, but as far as we know, these worlds settled in light and life are destined to go on throughout the eternal ages of all future time.
55:7.1This epoch extends from the appearance of the morontia temple at the new planetary headquarters to the time of the settling of the entire system in light and life. This age is inaugurated by the Trinity Teacher Sons at the close of their successive world missions when the Planetary Prince is elevated to the status of Planetary Sovereign by the mandate and personal presence of the Paradise bestowal Son of that sphere. Concomitant therewith the finaliters inaugurate their active participation in planetary affairs.
55:7.2To outward and visible appearances the actual rulers, or directors, of such a world settled in light and life are the Material Son and Daughter, the Planetary Adam and Eve. The finaliters are invisible, as also is the Prince-Sovereign except when in the morontia temple. The actual and literal heads of the planetary regime are therefore the Material Son and Daughter. It is the knowledge of these arrangements that has given prestige to the idea of kings and queens throughout the universe realms. And kings and queens are a great success under these ideal circumstances, when a world can command such high personalities to act in behalf of still higher but invisible rulers.
55:7.3When such an era is attained on your world, no doubt Machiventa Melchizedek, now the vicegerent Planetary Prince of Urantia, will occupy the seat of the Planetary Sovereign; and it has long been conjectured on Jerusem that he will be accompanied by a son and daughter of the Urantia Adam and Eve who are now held on Edentia as wards of the Most Highs of Norlatiadek. These children of Adam might so serve on Urantia in association with the Melchizedek-Sovereign since they were deprived of procreative powers almost 37,000 years ago at the time they gave up their material bodies on Urantia in preparation for transit to Edentia.
55:7.4This settled age continues on and on until every inhabited planet in the system attains the era of stabilization; and then, when the youngest world—the last to achieve light and life—has experienced such settledness for one millennium of system time, the entire system enters the stabilized status, and the individual worlds are ushered into the system epoch of the era of light and life.
55:11.6Let it be made clear that the administrative mechanisms and governmental techniques of a universe or a superuniverse cannot in any manner limit or retard the evolutionary development or spiritual progress of an individual inhabited planet or of any individual mortal on such a sphere.
57:5.15,000,000,000 years ago your sun was a comparatively isolated blazing orb, having gathered to itself most of the near-by circulating matter of space, remnants of the recent upheaval which attended its own birth.
57:5.2Today, your sun has achieved relative stability, but its eleven and one-half year sunspot cycles betray that it was a variable star in its youth. In the early days of your sun the continued contraction and consequent gradual increase of temperature initiated tremendous convulsions on its surface. These titanic heaves required three and one-half days to complete a cycle of varying brightness. This variable state, this periodic pulsation, rendered your sun highly responsive to certain outside influences which were to be shortly encountered.
57:5.3Thus was the stage of local space set for the unique origin of Monmatia, that being the name of your sun’s planetary family, the solar system to which your world belongs. Less than one per cent of the planetary systems of Orvonton have had a similar origin.
57:5.44,500,000,000 years ago the enormous Angona system began its approach to the neighborhood of this solitary sun. The center of this great system was a dark giant of space, solid, highly charged, and possessing tremendous gravity pull.
57:5.5As Angona more closely approached the sun, at moments of maximum expansion during solar pulsations, streams of gaseous material were shot out into space as gigantic solar tongues. At first these flaming gas tongues would invariably fall back into the sun, but as Angona drew nearer and nearer, the gravity pull of the gigantic visitor became so great that these tongues of gas would break off at certain points, the roots falling back into the sun while the outer sections would become detached to form independent bodies of matter, solar meteorites, which immediately started to revolve about the sun in elliptical orbits of their own.
57:5.6As the Angona system drew nearer, the solar extrusions grew larger and larger; more and more matter was drawn from the sun to become independent circulating bodies in surrounding space. This situation developed for about five hundred thousand years until Angona made its closest approach to the sun; whereupon the sun, in conjunction with one of its periodic internal convulsions, experienced a partial disruption; from opposite sides and simultaneously, enormous volumes of matter were disgorged. From the Angona side there was drawn out a vast column of solar gases, rather pointed at both ends and markedly bulging at the center, which became permanently detached from the immediate gravity control of the sun.
57:5.7This great column of solar gases which was thus separated from the sun subsequently evolved into the twelve planets of the solar system. The repercussional ejection of gas from the opposite side of the sun in tidal sympathy with the extrusion of this gigantic solar system ancestor, has since condensed into the meteors and space dust of the solar system, although much, very much, of this matter was subsequently recaptured by solar gravity as the Angona system receded into remote space.
57:5.8Although Angona succeeded in drawing away the ancestral material of the solar system planets and the enormous volume of matter now circulating about the sun as asteroids and meteors, it did not secure for itself any of this solar matter. The visiting system did not come quite close enough to actually steal any of the sun’s substance, but it did swing sufficiently close to draw off into the intervening space all of the material comprising the present-day solar system.
57:5.9The five inner and five outer planets soon formed in miniature from the cooling and condensing nucleuses in the less massive and tapering ends of the gigantic gravity bulge which Angona had succeeded in detaching from the sun, while Saturn and Jupiter were formed from the more massive and bulging central portions. The powerful gravity pull of Jupiter and Saturn early captured most of the material stolen from Angona as the retrograde motion of certain of their satellites bears witness.
57:5.10Jupiter and Saturn, being derived from the very center of the enormous column of superheated solar gases, contained so much highly heated sun material that they shone with a brilliant light and emitted enormous volumes of heat; they were in reality secondary suns for a short period after their formation as separate space bodies. These two largest of the solar system planets have remained largely gaseous to this day, not even yet having cooled off to the point of complete condensation or solidification.
57:5.11The gas-contraction nucleuses of the other ten planets soon reached the stage of solidification and so began to draw to themselves increasing quantities of the meteoric matter circulating in near-by space. The worlds of the solar system thus had a double origin: nucleuses of gas condensation later on augmented by the capture of enormous quantities of meteors. Indeed they still continue to capture meteors, but in greatly lessened numbers.
57:5.12The planets do not swing around the sun in the equatorial plane of their solar mother, which they would do if they had been thrown off by solar revolution. Rather, they travel in the plane of the Angona solar extrusion, which existed at a considerable angle to the plane of the sun’s equator.
57:5.13While Angona was unable to capture any of the solar mass, your sun did add to its metamorphosing planetary family some of the circulating space material of the visiting system. Due to the intense gravity field of Angona, its tributary planetary family pursued orbits of considerable distance from the dark giant; and shortly after the extrusion of the solar system ancestral mass and while Angona was yet in the vicinity of the sun, three of the major planets of the Angona system swung so near to the massive solar system ancestor that its gravitational pull, augmented by that of the sun, was sufficient to overbalance the gravity grasp of Angona and to permanently detach these three tributaries of the celestial wanderer.
57:5.14All of the solar system material derived from the sun was originally endowed with a homogeneous direction of orbital swing, and had it not been for the intrusion of these three foreign space bodies, all solar system material would still maintain the same direction of orbital movement. As it was, the impact of the three Angona tributaries injected new and foreign directional forces into the emerging solar system with the resultant appearance of retrograde motion. Retrograde motion in any astronomic system is always accidental and always appears as a result of the collisional impact of foreign space bodies. Such collisions may not always produce retrograde motion, but no retrograde ever appears except in a system containing masses which have diverse origins.
57:6.1Subsequent to the birth of the solar system a period of diminishing solar disgorgement ensued. Decreasingly, for another five hundred thousand years, the sun continued to pour forth diminishing volumes of matter into surrounding space. But during these early times of erratic orbits, when the surrounding bodies made their nearest approach to the sun, the solar parent was able to recapture a large portion of this meteoric material.
57:6.2The planets nearest the sun were the first to have their revolutions slowed down by tidal friction. Such gravitational influences also contribute to the stabilization of planetary orbits while acting as a brake on the rate of planetary-axial revolution, causing a planet to revolve ever slower until axial revolution ceases, leaving one hemisphere of the planet always turned toward the sun or larger body, as is illustrated by the planet Mercury and by the moon, which always turns the same face toward Urantia.
57:6.3When the tidal frictions of the moon and the earth become equalized, the earth will always turn the same hemisphere toward the moon, and the day and month will be analogous—in length about forty-seven days. When such stability of orbits is attained, tidal frictions will go into reverse action, no longer driving the moon farther away from the earth but gradually drawing the satellite toward the planet. And then, in that far-distant future when the moon approaches to within about eleven thousand miles of the earth, the gravity action of the latter will cause the moon to disrupt, and this tidal-gravity explosion will shatter the moon into small particles, which may assemble about the world as rings of matter resembling those of Saturn or may be gradually drawn into the earth as meteors.
57:6.4If space bodies are similar in size and density, collisions may occur. But if two space bodies of similar density are relatively unequal in size, then, if the smaller progressively approaches the larger, the disruption of the smaller body will occur when the radius of its orbit becomes less than two and one-half times the radius of the larger body. Collisions among the giants of space are rare indeed, but these gravity-tidal explosions of lesser bodies are quite common.
57:6.5Shooting stars occur in swarms because they are the fragments of larger bodies of matter which have been disrupted by tidal gravity exerted by near-by and still larger space bodies. Saturn’s rings are the fragments of a disrupted satellite. One of the moons of Jupiter is now approaching dangerously near the critical zone of tidal disruption and, within a few million years, will either be claimed by the planet or will undergo gravity-tidal disruption. The fifth planet of the solar system of long, long ago traversed an irregular orbit, periodically making closer and closer approach to Jupiter until it entered the critical zone of gravity-tidal disruption, was swiftly fragmentized, and became the present-day cluster of asteroids.
57:6.64,000,000,000 years ago witnessed the organization of the Jupiter and Saturn systems much as observed today except for their moons, which continued to increase in size for several billions of years. In fact, all of the planets and satellites of the solar system are still growing as the result of continued meteoric captures.
57:6.73,500,000,000 years ago the condensation nucleuses of the other ten planets were well formed, and the cores of most of the moons were intact, though some of the smaller satellites later united to make the present-day larger moons. This age may be regarded as the era of planetary assembly.
57:6.83,000,000,000 years ago the solar system was functioning much as it does today. Its members continued to grow in size as space meteors continued to pour in upon the planets and their satellites at a prodigious rate.
57:6.9About this time your solar system was placed on the physical registry of Nebadon and given its name, Monmatia.
57:6.102,500,000,000 years ago the planets had grown immensely in size. Urantia was a well-developed sphere about one tenth its present mass and was still growing rapidly by meteoric accretion.
57:6.11All of this tremendous activity is a normal part of the making of an evolutionary world on the order of Urantia and constitutes the astronomic preliminaries to the setting of the stage for the beginning of the physical evolution of such worlds of space in preparation for the life adventures of time.
57:7.1Throughout these early times the space regions of the solar system were swarming with small disruptive and condensation bodies, and in the absence of a protective combustion atmosphere such space bodies crashed directly on the surface of Urantia. These incessant impacts kept the surface of the planet more or less heated, and this, together with the increased action of gravity as the sphere grew larger, began to set in operation those influences which gradually caused the heavier elements, such as iron, to settle more and more toward the center of the planet.
57:7.22,000,000,000 years ago the earth began decidedly to gain on the moon. Always had the planet been larger than its satellite, but there was not so much difference in size until about this time, when enormous space bodies were captured by the earth. Urantia was then about one fifth its present size and had become large enough to hold the primitive atmosphere which had begun to appear as a result of the internal elemental contest between the heated interior and the cooling crust.
57:7.3Definite volcanic action dates from these times. The internal heat of the earth continued to be augmented by the deeper and deeper burial of the radioactive or heavier elements brought in from space by the meteors. The study of these radioactive elements will reveal that Urantia is more than one billion years old on its surface. The radium clock is your most reliable timepiece for making scientific estimates of the age of the planet, but all such estimates are too short because the radioactive materials open to your scrutiny are all derived from the earth’s surface and hence represent Urantia’s comparatively recent acquirements of these elements.
57:7.41,500,000,000 years ago the earth was two thirds its present size, while the moon was nearing its present mass. Earth’s rapid gain over the moon in size enabled it to begin the slow robbery of the little atmosphere which its satellite originally had.
57:7.5Volcanic action is now at its height. The whole earth is a veritable fiery inferno, the surface resembling its earlier molten state before the heavier metals gravitated toward the center. This is the volcanic age. Nevertheless, a crust, consisting chiefly of the comparatively lighter granite, is gradually forming. The stage is being set for a planet which can someday support life.
57:7.6The primitive planetary atmosphere is slowly evolving, now containing some water vapor, carbon monoxide, carbon dioxide, and hydrogen chloride, but there is little or no free nitrogen or free oxygen. The atmosphere of a world in the volcanic age presents a queer spectacle. In addition to the gases enumerated it is heavily charged with numerous volcanic gases and, as the air belt matures, with the combustion products of the heavy meteoric showers which are constantly hurtling in upon the planetary surface. Such meteoric combustion keeps the atmospheric oxygen very nearly exhausted, and the rate of meteoric bombardment is still tremendous.
57:7.7Presently, the atmosphere became more settled and cooled sufficiently to start precipitation of rain on the hot rocky surface of the planet. For thousands of years Urantia was enveloped in one vast and continuous blanket of steam. And during these ages the sun never shone upon the earth’s surface.
57:7.8Much of the carbon of the atmosphere was abstracted to form the carbonates of the various metals which abounded in the superficial layers of the planet. Later on, much greater quantities of these carbon gases were consumed by the early and prolific plant life.
57:7.9Even in the later periods the continuing lava flows and the incoming meteors kept the oxygen of the air almost completely used up. Even the early deposits of the soon appearing primitive ocean contain no colored stones or shales. And for a long time after this ocean appeared, there was virtually no free oxygen in the atmosphere; and it did not appear in significant quantities until it was later generated by the seaweeds and other forms of vegetable life.
57:7.10The primitive planetary atmosphere of the volcanic age affords little protection against the collisional impacts of the meteoric swarms. Millions upon millions of meteors are able to penetrate such an air belt to smash against the planetary crust as solid bodies. But as time passes, fewer and fewer prove large enough to resist the ever-stronger friction shield of the oxygen-enriching atmosphere of the later eras.
112:0.1The evolutionary planets are the spheres of human origin, the initial worlds of the ascending mortal career. Urantia is your starting point; here you and your divine Thought Adjuster are joined in temporary union. You have been endowed with a perfect guide; therefore, if you will sincerely run the race of time and gain the final goal of faith, the reward of the ages shall be yours; you will be eternally united with your indwelling Adjuster. Then will begin your real life, the ascending life, to which your present mortal state is but the vestibule. Then will begin your exalted and progressive mission as finaliters in the eternity which stretches out before you. And throughout all of these successive ages and stages of evolutionary growth, there is one part of you that remains absolutely unaltered, and that is personality—permanence in the presence of change.
