The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets.
The nebular hypothesis was first proposed in 1734 by Swedish scientist Emanuel Swedenborg [6] and later expanded upon by Prussian philosopher Immanuel Kant in 1755. A similar hypothesis was independently formulated by the Frenchman Pierre-Simon Laplace in 1796. [7]
Pierre-Simon Laplace, one of the originators of the nebular hypothesis. Ideas concerning the origin and fate of the world date from the earliest known writings; however, for almost all of that time, there was no attempt to link such theories to the existence of a "Solar System", simply because it was not generally thought that the Solar System, in the sense we now understand it, existed.
In 1905, Chamberlin and Forest Ray Moulton developed a theory of the formation of the Solar System that challenged the Laplacian nebular hypothesis. Their theory, the Chamberlin-Moulton planetesimal hypothesis , received favorable support for almost a third of a century, but passed out of favor by the late 1930s.
In cosmogony, the nebular hypothesis is the most widely accepted model explaining the formation and evolution of the Solar System. It was first proposed in 1734 by Emanuel Swedenborg . Originally applied only to our own Solar System , this method of planetary system formation is now thought to be at work throughout the universe .
Laplace developed the nebular hypothesis of the formation of the Solar System, first suggested by Emanuel Swedenborg and expanded by Immanuel Kant. This hypothesis remains the most widely accepted model in the study of the origin of planetary systems.
Nichol turned to popular lecturing and authored a number of popular and successful books about astronomy, especially championing the nebular hypothesis. [ 2 ] [ 4 ] In 1841 George Eliot wrote: [ 1 ] I have been revelling in Nichol's Architecture of the Heavens and Phenomena of the Solar System , and have been in imagination winging my flight ...
The Solar System is believed to have formed according to the nebular hypothesis, first proposed in 1755 by Immanuel Kant and independently formulated by Pierre-Simon Laplace. [2] This theory holds that 4.6 billion years ago the Solar System formed from the gravitational collapse of a giant molecular cloud. This initial cloud was likely several ...
