After long-term observation and research, he created a more scientific cosmic structure theory, that is, he denied the Western domination of geocentrism for more than a thousand years, and believed that this was a great astronomical revolution, which not only led to the great expansion of the human universe From then on, natural science began to be liberated from theology, and the development of science would never take great strides (Engels' Dialectics of nature).
