"It confirms the nebular hypothesis!"
"How so?" Smith wanted to know.
"Because it proves that the process of condensation and
concentration, which produces planets out of the original gases can
take place at uneven speeds! Instead of concentrating to the
globular form, Sanus cooled too quickly; she concentrated while she
was still a ring!"
Smith was struck with another phase of the matter. "Must have a
queer sort of gravitation," he pointed out. "Seems to be the same,
inside the ring or outside. Surely, doc it can't be as powerful as
it is here on the earth?"
"No; not likely."
"Then, why hasn't it made a difference in the inhabitants? Seems to
me the humans would have different structure."
"Not necessarily. Look at it the other way around; consider what an
enormous variety of animal forms we have here, all developed under
the same conditions. The humming-bird and the python, for instance.
Gravitation needn't have anything to do with it."
Billie was thinking mainly of the question of day and night.
