Detailed explanation-1: -Kant and Laplace proposed the “nebular hypothesis” of the origin of the solar system, whereby the planets formed from condensation out of matter orbiting the early Sun.
Detailed explanation-2: -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.
Detailed explanation-3: -Kant-Laplace Theory: Kant assumed that the gravitational force of all the dispersed particles led to their movement and collisions. Kant’s model of the solar system did not include the concept of planets moving around the sun nor did it include the concept of revolution.
Detailed explanation-4: -The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12].
Detailed explanation-5: -The first version of the nebular hypothesis was proposed in 1755 by the German philosopher Immanuel Kant and modified in 1796 by Pierre Laplace. The nebula that according to this hypothesis condensed to form the solar system is called the solar nebula.
