Question
What is the basic difference in the arguments related to the origin of the earth given by :
(a) Kant and Laplace
(b) Chamberlain and Moulton?
Solution
The Nebular Hypothesis, as proposed by Immanuel Kant and later revised by Laplace in 1796 considered that the planets were formed out of a cloud of material associated with a youthful sun, which was slowly rotating while, in 1900, Chamberlain and Moulton considered that a wandering star approached the sun.
As a result, a cigar-shaped material separated from the solar surface. As the passing star moved away, the material separated from the sun, continued to revolve around the sun and it slowly condensed into planets.
