Physical Aspects of Jerusem

The Urantia Book; Paper 45, Section 1

^{P519:2, 46:1.1} Jerusem is divided into one thousand latitudinal sectors and ten thousand longitudinal zones. The sphere has seven major capitals and seventy minor administrative centers. The seven sectional capitals are concerned with diverse activities, and the System Sovereign is present in each at least once a year.

^{P519:3, 46:1.2} The standard mile of Jerusem is equivalent to about seven Urantia miles. The standard weight, the " gradant," is built up through the decimal system from the mature ultimaton and represents almost exactly ten ounces of your weight. The Satania day equals three days of Urantia time, less one hour, four minutes, and fifteen seconds, that being the time of the axial revolution of Jerusem. The system year consists of one hundred Jerusem days. The time of the system is broadcast by the master chronoldeks.

^{P519:4, 46:1.3} The energy of Jerusem is superbly controlled and circulates about the sphere in the zone channels, which are directly fed from the energy charges of space and expertly administered by the Master Physical Controllers. The natural resistance to the passage of these energies through the physical channels of conduction yields the heat required for the production of the equable temperature of Jerusem. The full-light temperature is maintained at about 70 degrees Fahrenheit, while during the period of light recession it falls to a little lower than 50 degrees.

^{P519:5, 46:1.4} The lighting system of Jerusem should not be so difficult for you to comprehend. There are no days and nights, no seasons of heat and cold. The power transformers maintain one hundred thousand centers from which rarefied energies are projected upward through the planetary atmosphere, undergoing certain changes, until they reach the electric air- ceiling of the sphere; and then these energies are reflected back and down as a gentle, sifting, and even light of about the intensity of Urantia sunlight when the sun is shining overhead at ten o'clock in the morning.

^{P520:1, 46:1.5} Under such conditions of lighting, the light rays do not seem to come from one place; they just sift out of the sky, emanating equally from all space directions. This light is very similar to natural sunlight except that it contains very much less heat. Thus it will be recognized that such headquarters worlds are not luminous in space; if Jerusem were very near Urantia, it would not be visible.

^{P520:2, 46:1.6} The gases which reflect this light-energy from the Jerusem upper ionosphere back to the ground are very similar to those in the Urantia upper air belts which are concerned with the auroral phenomena of your so-called northern lights, although these are produced by different causes. On Urantia it is this same gas shield which prevents the escape of the terrestrial broadcast waves, reflecting them earthward when they strike this gas belt in their direct outward flight. In this way broadcasts are held near the surface as they journey through the air around your world.

^{P520:3, 46:1.7} This lighting of the sphere is uniformly maintained for seventy-five per cent of the Jerusem day, and then there is a gradual recession until, at the time of minimum illumination, the light is about that of your full moon on a clear night. This is the quiet hour for all Jerusem. Only the broadcast-receiving stations are in operation during this period of rest and rehabilitation.

^{P520:4, 46:1.8}   Jerusem receives faint light from several near-by suns -- a sort of brilliant starlight -- but it is not dependent on them; worlds like Jerusem are not subject to the vicissitudes of sun disturbances, neither are they confronted with the problem of a cooling or dying sun.
^{P520:5, 46:1.9} The seven transitional study worlds and their forty-nine satellites are heated, lighted, energized, and watered by the Jerusem technique.
