The metaphysical view that the universe will never change fetters scientists' thoughts. They seldom think about the origin of the solar system or the universe and cannot answer the above questions. The first person who put forward the answer was not a scientist, but a German philosopher Kant, whose philosophy was unique. Different from the mechanical materialism represented by Newton, Shabnitz and others developed dialectics. Vegetable Bunitz is the first president of Berlin Academy of Sciences, and his philosophy is basically idealistic. He disagreed with Newton's view of absolute structure and thought that space and matter were inseparable. He also believes that present things have the concept of gestating the future and developing and evolving. Kant inherited and developed the dialectical factors in Shabnitz's philosophy.

Kant was born into a family of craftsmen and completed his high school and college studies in Konigsberg. After graduating from college, he worked as a tutor for eight years and read a lot of books in his spare time. His major scientific achievements were made during this period. Later, he taught philosophy, mathematics, physics, geography, anthropology and natural history at Gunsburg University for nearly 30 years. Kant is very concerned about the development of natural science and resolutely opposes metaphysical views. British astronomer Wright (171-1786) published a paper on the Milky Way. Previously, French mathematician and astronomer Mo Podio (1698- 1759) mentioned "polysaccharide" in his paper. Based on the existing scientific knowledge at that time, Kant boldly explored the origin of celestial bodies under the inspiration of predecessors' thoughts. At the age of 3 1, Kant published the General History of Nature and the Theory of Celestial Bodies (introduction to the development of the universe), and put forward the nebula hypothesis of the origin of the solar system for the first time.

Prototypes of planetary orbits, that is, their orbits are very close to the garden. French naturalist Fu Feng (1707 ~ 1788) inferred from these facts that the motions of the planets must be caused by a common cause. He imagined that our solar system was formed by the accidental meeting of comets and the sun, and some material fragments extracted from the sun by comets formed six planets one after another.

Under the ideological background of this era, the German philosopher Kant (1724 ~ 1804) put forward the nebula hypothesis of the origin of the solar system. 175 1 year, an Englishman Wright (171kloc-0/~1786) observed the Milky Way and thought that the stars in the Milky Way were generally distributed on the same plane. This inspired Kant, who believed that the solar system was similar to the Milky Way, and the Milky Way as a whole was also rotating. He is reminiscent of many "clouds" found at that time, that is, nebulae, which are all galaxies. Therefore, in the "General History of Nature and Celestial Theory" published by 1755 (generally translated as "Introduction to the Development of the Universe"), he put forward his own theory that the solar system evolved from nebulae.
