In the 12th century, [[Abū Ishāq Ibrāhīm al-Zarqālī|Arzachel]] departed from the ancient Greek idea of [[uniform circular motion]]s by hypothesizing that the planet [[Mercury (planet)|Mercury]] moves in an [[elliptic orbit]],<ref name= "Rufus1939"/><ref name= "Hartner1955"/> while [[Nur ad-Din al-Bitruji|Alpetragius]] proposed a planetary model that abandoned the [[equant]], [[Deferent and epicycle|epicycle and eccentric]] mechanisms,<ref name= "Goldstein1972"/> though this resulted in a system that was mathematically less accurate.<ref name= "Gale"/> [[Fakhr al-Din al-Razi]] (1149–1209), in dealing with his [[Physics in medieval Islam|conception of physics]] and the physical world in his ''Matalib'', rejects the [[Aristotelianism|Aristotelian]] and [[Avicennism|Avicennian]] notion of the Earth's centrality within the universe, but instead argues that there are "a thousand thousand worlds (''alfa alfi 'awalim'') beyond this world such that each one of those worlds be bigger and more massive than this world as well as having the like of what this world has." To support his [[Islamic theology|theological argument]], he cites the [[Qur'an]]ic verse, "All praise belongs to God, Lord of the Worlds," emphasizing the term "Worlds."<ref name= "Setia2004"/>
The "Maragha Revolution" refers to the Maragha school's revolution against Ptolemaic astronomy. The "Maragha school" was an astronomical tradition beginning in the [[Maragheh observatory|Maragha observatory]] and continuing with astronomers from the [[Umayyad Mosque|Damascus mosque]] and [[Ulugh Beg Observatory|Samarkand observatory]]. Like their [[Al-Andalus|Andalusian]] predecessors, the Maragha astronomers attempted to solve the [[equant]] problem (the circle around whose circumference a planet or the center of an [[epicycle]] was conceived to move uniformly) and produce alternative configurations to the Ptolemaic model without abandoning geocentrism. They were more successful than their Andalusian predecessors in producing non-Ptolemaic configurations which eliminated the equant and eccentrics, were more accurate than the Ptolemaic model in numerically predicting planetary positions, and were in better agreement with empirical observations.<ref name= "Saliba1994"/> The most important of the Maragha astronomers included [[Mo'ayyeduddin Urdi]] (d. 1266), [[Nasīr al-Dīn al-Tūsī]] (1201–1274), [[Qutb al-Din al-Shirazi]] (1236–1311), [[Ibn al-Shatir]] (1304–1375), [[Ali Qushji]] (c. 1474), [[Al-Birjandi]] (d. 1525), and Shams al-Din al-Khafri (d. 1550).<ref name= "Dallal1999"/> [[Ibn al-Shatir]], the Damascene astronomer (1304–1375 AD) working at the [[Umayyad Mosque]], wrote a major book entitled ''Kitab Nihayat al-Sul fi Tashih al-Usul'' (''A Final Inquiry Concerning the Rectification of Planetary Theory'') on a theory which departs largely from the Ptolemaic system known at that time. In his book, "Ibn al-Shatir, an Arab astronomer of the fourteenth century," E. S. Kennedy wrote "what is of most interest, however, is that Ibn al-Shatir's lunar theory, except for trivial differences in parameters, is identical with that of [[Nicolaus Copernicus|Copernicus]] (1473–1543 AD)." The discovery that the models of Ibn al-Shatir are mathematically identical to those of Copernicus suggests the possible transmission of these models to Europe.<ref name= "Guessoun2008"/> At the Maragha and [[Ulugh Beg Observatory|Samarkand observatories]], the [[Earth's rotation]] was discussed by al-Tusi and [[Ali Qushji]] (b. 1403); the arguments and evidence they used resemble those used by Copernicus to support the Earth's motion.<ref name= "Ragep2001a"

However, the Maragha school never made the [[paradigm shift]] to heliocentrism.<ref name="Huff2003"/> The influence of the Maragha school on [[Copernicus]] remains speculative, since there is no documentary evidence to prove it. The possibility that Copernicus independently developed the Tusi couple remains open, since no researcher has yet demonstrated that he knew about Tusi's work or that of the Maragha school.<ref name="Huff2003">{{cite book |last= Huff |first= Toby E. |title= The Rise of Early Modern Science: Islam, China and the West |year= 2003 |publisher= Cambridge University Press |isbn= 9780521529945 |page= [http://books.google.com/books?id=DA3fkX5wQMUC&pg=PA58 58]}}</ref><ref name="KirmaniSingh2005">{{cite book |last1= Kirmani |first1= M.

Model Ptolemaik mengenai tata surya masih terus dianut sampai ke awal zaman modern. Sejak akhir abad ke-16 dan seterusnya perlahan-lahan digantikan sebagai penggambaran konsensus oleh model heliosentrisme. Geosentrisme sebagai suatu kepercayaan agamawi terpisah, tidak pernah padam. Di Amerika Serikat antara tahun 1870-1920, misalnya, berbagai anggota [[Gereja Lutheran – Sinode Missouri]] menerbitkan artikel-artikel yang menyerang sistem astronomi Kopernikan, dan geosentrisme banyak diajarkan di dalam sinode dalam periode tersebut.<ref name= "Babinski1995">{{cite journal |editor-last= Babinski |editor-first= E.

L. Graebner menyatakan bahwa sinode itu tidak mempunyai posisi doktrinal terhadap geosentrisme, heliosentrisme, atau model ilmiah lainnya, kecuali kalau itu bertolak belakang dengan [[Alkitab]]. Ia menyatakan pula bahwa deklarasi apapun yang dikemukakan para penganut geosentrisme di dalam sinode bukan merupakan pendapat badan gereja secara keseluruhan.<ref name= "Graebner1902">{{cite journal |title= Science and the church |journal= Theological Quarterly |first= A.

Artikel-artikel yang mendukung geosentrisme sebagai pandangan Alkitab muncul pada sejumlah surat kabar sains penciptaan yang berhubungan dengan [[Creation Research Society]]. Umumnya menunjuk kepada beberapa nas [[Alkitab]], yang secara harfiah mengindikasikan pergerakan harian Matahari dan Bulan yang dapat diamati mengelilingi Bumi, bukan karena rotasi Bumi pada aksisnya, misalnya pada {{Alkitab|Yosua 10:12}} di mana Matahari dan Bulan dikatakan berhenti di langit, dan {{Alkitab|Mazmur 93:1}} di mana dunia digambarkan tidak bergerak..<ref name= "Numbers1993">{{cite book |title= The Creationists: The Evolution of Scientific Creationism |publisher= University of California Press |last= Numbers |first= Ronald L. |authorlink= Ronald L.

=== Posisi historis hierarki Katolik Roma ===
:we have to contend against those who, making an evil use of physical science, minutely scrutinize the Sacred Book in order to detect the writers in a mistake, and to take occasion to vilify its contents. . . . There can never, indeed, be any real discrepancy between the theologian and the physicist, as long as each confines himself within his own lines, and both are careful, as St. Augustine warns us, "not to make rash assertions, or to assert what is not known as known." If dissension should arise between them, here is the rule also laid down by St. Augustine, for the theologian: "Whatever they can really demonstrate to be true of physical nature, we must show to be capable of reconciliation with our Scriptures; and whatever they assert in their treatises which is contrary to these Scriptures of ours, that is to Catholic faith, we must either prove it as well as we can to be entirely false, or at all events we must, without the smallest hesitation, believe it to be so." To understand how just is the rule here formulated we must remember, first, that the sacred writers, or to speak more accurately, the Holy Ghost "Who spoke by them, did not intend to teach men these things (that is to say, the essential nature of the things of the visible universe), things in no way profitable unto salvation." Hence they did not seek to penetrate the secrets of nature, but rather described and dealt with things in more or less figurative language, or in terms which were commonly used at the time, and which in many instances are in daily use at this day, even by the most eminent men of science. Ordinary speech primarily and properly describes what comes under the senses; and somewhat in the same way the sacred writers-as the Angelic Doctor also reminds us – `went by what sensibly appeared," or put down what God, speaking to men, signified, in the way men could understand and were accustomed to. ([[Providentissimus Deus]] 18).
