In 1913, Danish physicist Niels Bohr applied Max Planck’s quantum theory to the nuclear atom of Ernest … There is evidence that Emanuel Swedenborg first proposed parts of the nebular theory in 1734. 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 collapse and flatten due to gravity, eventually forming stars and planets.
