  2. Nebular hypothesis - Wikipedia

    en.wikipedia.org/wiki/Nebular_hypothesis

    There is evidence that Emanuel Swedenborg first proposed parts of the nebular theory in 1734. [ 5 ] [ 6 ] Immanuel Kant , familiar with Swedenborg's work, developed the theory further in 1755, publishing his own Universal Natural History and Theory of the Heavens , wherein he argued that gaseous clouds ( nebulae ) slowly rotate, gradually ...

    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]

    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.

  5. Formation and evolution of the Solar System - Wikipedia

    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]

    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 ...

  7. Universal Natural History and Theory of the Heavens - Wikipedia

    en.wikipedia.org/wiki/Universal_Natural_History...

    Kant proposes the nebular hypothesis, in which solar systems are the result of nebulae (interstellar clouds of dust) coalescing into accretion disks and then forming suns and their planets. [4] He also discusses comets, and postulates that the Milky Way is only one of many galaxies. [1]

    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.

  9. Chamberlin–Moulton planetesimal hypothesis - Wikipedia

    en.wikipedia.org/wiki/Chamberlin–Moulton...

    The Chamberlin–Moulton planetesimal hypothesis was proposed in 1905 by geologist Thomas Chrowder Chamberlin and astronomer Forest Ray Moulton to describe the formation of the Solar System. It was proposed as a replacement for the Laplacian version of the nebular hypothesis that had prevailed since the 19th century.
