Why Couldn’t Muslim Astronomers Discover the Heliocentric System?
Abstract
Extended Abstract
It comes to question the reasons why Muslim astronomers could not recognize the centrality of the Sun in the planetary system. While Europeans have spent centuries in their dark ages, Muslims spent the same centuries trying to verify the Ptolemaic planetary theory which has adopted the assumption of geocentricism, both theoretically and observationally. Many generations of Muslim astronomers from the 8th century to the 15th century lived circling in boring games of epicycles and deferments. Undoubtedly, Muslim astronomers devoted great efforts for developing the astronomical observations. For this purpose, they invented and developed many precise astronomical instruments and on the side of scientific literature, they wrote thousands of manuscripts in astronomy and observational techniques.
