ebular ring separated (like the present ring around Saturn)
from the rotating ball. In time the nebulous ring condensed to a planet,
which began to revolve around its own axis. When the centrifugal force
became more powerful than the centripetal force in the planet, rings
were formed, which, in turn, formed planets which revolved around their
axes, as also around their planets, as the latter moved around the sun,
and thus arose the moons, only one of which moves around our earth,
while four move around Jupiter and six around Uranus. This order of
things was repeated over and over again until thereby arose the
different solar systems--the planets rotating around their central suns,
and the satellites or moons moving around their planets. By a continuous
increasing of refrigeration and condensation, a fiery fluid or molten
state occurred in these rotating bodies. They then emitted an enormous
amount of heat by rapid condensation, and the rotating bodies--suns,
planets, and moons--soon became glowing balls of fire, emitting light
and heat. The 1/1000 part of a pound of magnesium wire, burning in the
open air, will give a light which will last during one second, and can
be seen at a distance of thirty miles; imagine, then, what the light
would be from these huge balls of fire floating through space. The earth
forms a small part--nay, even the sun whose mass is equal to 354,936
earths like ours, is but an infinitesimal portion of the whole. By the
continual emitting of heat, however, these fiery balls had a crust form
on the outside, which enclosed a fiery fluid nucleus. The crust for a
time must have been a smooth sheet, but afterward very uneven, having
protuberances and cavities form over its surface, owing to the molten
mass within becoming condensed and contracted; the crust not following
this change sufficiently close, must have fallen in, and thus produced
the cavities.
