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.
Pierre-Simon Laplace, one of the originators of the nebular hypothesis. The history of scientific thought about the formation and evolution of the Solar System began with the Copernican Revolution. The first recorded use of the term "Solar System" dates from 1704.
1796 – Pierre Laplace re-states the nebular hypothesis for the formation of the Solar System from a spinning nebula of gas and dust. [124] 1798 – Henry Cavendish accurately measures the gravitational constant in the laboratory, which allows the mass of the Earth to be derived, and hence the masses of all bodies in the Solar System. [125]
The nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud, [9] most likely at the edge of a Wolf-Rayet bubble. [10] The cloud was about 20 parsecs (65 light years) across, [9] while the fragments were roughly 1 parsec (three and a quarter light-years) across. [11]
His formula, at least approximately, matches the later model from Einstein's general relativity, but Gerber's theory was incorrect. 1902 – Henri Poincaré questions the concept of simultaneity in his book, Science and Hypothesis. [31] [32] 1904 – Hendrik Antoon Lorentz publishes the Lorentz transformations, [33] so named by Henri Poincaré ...
As mentioned, the idea of the nebular hypothesis had been outlined by Immanuel Kant in 1755, [58] who had also suggested "meteoric aggregations" and tidal friction as causes affecting the formation of the Solar System. Laplace was probably aware of this, but, like many writers of his time, he generally did not reference the work of others.

He also outlined his cosmology, which included the first presentation of his nebular hypothesis. (There is evidence that Swedenborg may have preceded Kant by as much as 20 years in the development of that hypothesis. [35]) Other inventions by Swedenborg include a submarine, an automatic weapon, an universal musical instrument, a system of ...
