Immanuel Kant
German philosopher Immanuel Kant surrounded by Ouroboros, an emblematic serpent of ancient Egypt and Greece, engraving by John Chapman, published in London, 1812.
In 1755, the German philosopher Immanuel Kant proposed a theory regarding the origin of the solar system known as the nebular hypothesis.
Kant suggested that the Sun and planets formed from a nebula that was in a state of slow rotation. He proposed that this gaseous cloud was gradually pulled together by its own gravitational force, eventually flattening into a spinning disk that gave birth to the Sun and the planets.12
