The theory was developed by Immanuel Kant and published in his Universal Natural History and Theory of the Heavens (1755) and then modified in 1796 by Pierre Laplace. Originally applied to the Solar System, the process of planetary system formation is now thought to be at work throughout the universe.
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]
Kant had read a 1751 review of Thomas Wright's An Original Theory or New Hypothesis of the Universe (1750), and he credited this with inspiring him in writing the Universal Natural History. [ 1 ] Kant answered to the call of the Berlin Academy Prize in 1754 [ 2 ] with the argument that the Moon's gravity would eventually cause its tidal locking ...
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. According to Laplace's description of the hypothesis, the Solar System evolved from a globular ...
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.
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 ...
1796 – Pierre Laplace re-states the nebular hypothesis for the formation of the Solar System from a spinning nebula of gas and dust. [ 75 ] 1826 – Heinrich Wilhelm Olbers puts forth Olbers' paradox .
He develops an analytical theory of tides, deduces the mass of the Moon, improves the calculation of cosmic orbits, and predicts that Saturn's rings will be found to rotate. Most notably, he propounds the modern nebular hypothesis, independently outlined by Kant.
