Meteors
From Urantia Wiki, the encyclopedia of The Urantia Book
The atmospheric oxygen was exhausted by the combustion of heavy meteoric showers on the primitive planetary surface. (57:7.6,9)
The shooting star, awesome to early man, sparked reverence for all stones. 85:1.2
Nonbreathing worlds in Satania are protected from meteor bombardment by advanced races with electrical installations, but still face great danger when venturing beyond these protected zones. 49:3.2-3
Comets and meteors comprise an enormous aggregate of energy and material substance in space. 15:6.12
Meteors are a source of solar energy by incessantly diving into blazing suns. 41:7.7
Millions of meteors could penetrate the primitive planetary atmosphere in the volcanic age, but fewer are able to resist the oxygen-enriching atmosphere in later eras. 57:7.10
Shooting stars and Saturn's rings are fragments of disrupted space bodies influenced by tidal gravity from larger space bodies. 57:6.5
Meteors, generally composed of heavy materials, accumulated on ocean bottoms, contributing to the increasing weight of the Pacific Ocean. 57:8.20
Primitive cultures viewed shooting stars and meteors as signs of special spirits descending to earth. 88:1.1
The sun recaptured a large portion of meteoric material during the early times of erratic orbits in the solar system's infancy. 57:6.1
2 billion to 1 billion years ago, during the meteoric era, incessant impacts of space bodies kept the surface of the planet heated, causing heavier elements to settle towards the center. 57:7
Millions upon millions of meteorites enter the atmosphere of Urantia daily at a rate of almost 200 miles per second, posing significant danger to nonbreathing worlds' inhabitants who must rely on electrical installations for protection. 49:3.3
Planets grow by accretion from meteoric collisions in space. 15:5.9
The primitive atmosphere afforded little protection against meteoric impacts in the volcanic age, but as time passed, fewer meteors were able to penetrate the oxygen-enriching atmosphere. 57:7.10
Angona drew away ancestral material from the solar system, but did not secure any solar matter itself. 57:5.8
In Satania, inhabited worlds without a protective atmosphere are rare due to the abundance of meteoric space bodies, including comets that consist of swarms of smaller disrupted matter. 49:3.2
