The small thousand worlds mentioned by the Buddha in the "Awakening Sutra" are the Milky Way, because the thousand suns and thousand moons that make up this small thousand world were put together by the Buddha, and said that this small thousand world It is shaped like "Zhou Luo", that is, it is not only disk-shaped, but also spiral, which is exactly the shape of the Milky Way; and these thousands of suns and thousands of moons all refer to the star system with life. When broken down, there are "Thousands of Jambudvipas" , Qianhudani, Qianfuboti, Qianyu Danyue', and 'Eighty Thousand Continents' are quite close to the 10,000 to 1 million star systems with advanced life in the Milky Way estimated by modern scientists. There are many small thousand worlds, one thousand small thousand worlds make up one middle thousand world, and one thousand middle thousand worlds make up one big thousand world, which means there are a large number of galaxies similar to the Milky Way in the universe.
The Buddha talked more about the four continents of 'Jambuti, Kudani, Fupati and Udan Yue', that is, the four types of planets
