Kant & Laplace – the most accepted theory, it explains the creation of stars and planets throughout the universe.
- There was a giant molecular gas cloud, which was interstellar and permitted the formation of molecular hydrogen
Due to self-gravity, the gas cloud contracts. since it is cold, internal pressure that can act outward is much less the force of internal gravity.
Conservation of angular momentum pulls the cloud into a desk
Early theories of origin.
- this theory was developed by Immanuel Kant and modified by Pierre Laplace
wandering star –
In 1900, Chamberlin and Moulton considered that a wandering star approached the sun which resulted in the formation of a cigar-shaped extension of material that got separated material that got separate from solar surface.This separated material continued to revolve around the sun and slowly got condensed
