Pierre-Simon Laplace independently developed and proposed a similar model in 1796 in his Exposition du systeme du monde. He envisioned that the Sun originally had an extended hot atmosphere throughout the volume of the Solar System. His theory featured a contracting and cooling protosolar cloud-the protosolar nebula.Pierre-Simon, marquis de Laplace was a French scholar whose work was important to the development of mathematics, statistics, physics and astronomy. He summarised and extended the work of his predecessors in his five-volume Mécanique Céleste.
Mam here James Jeans propounded the theory in 1919 and was modified by Harold Jeffery in 1929
