Wang Chong
Although Wang Chong was certain of his ideas about eclipses (without the knowledge of how gravity forms naturally large spherical bodies in space), his ideas on this would not be later accepted in China. Although there were some figures like "Liu Chi", writing in his Lun Tian (Discourse on the Heavens) of 274 AD that supported Wang's theory by arguing the inferior Yin (moon) could never obstruct the superior Yang (sun), Liu was still outside of the mainstream accepted Confucian tradition. The Song Dynasty (960-1279) polymathic scientist Shen Kuo (1031–1095) supported the old theory of a spherical sun and moon by using his own reasoning about eclipses, which he explained were due to the moon and the sun coming into obstruction of one another. The Song dynasty Chinese philosopher Zhu Xi (1130–1200) also supported this theory in his writing. Although Wang Chong was right about the water cycle and other aspects of early science, his stern opposition to mainstream Confucian thought at the time made him a skeptic of all their theories, including eclipses (the Confucian-accepted model being correct).
