Fakhr al Din al-Razi (died 1209 A.D. 606 A.H.) questioned Aristotle’s claim that stars were immobile and equidistant from the earth, as well as the claim that the movements of other heavenly bodies were all alike and similar.
Fakhr al Din al Razi (aliyekufa 1209 BK 606 BH) alihoji tamko la Aristotle kwamba nyota hazibadili nafasi zake na ziko mbali na dunia, pia tamko lisemalo kuwa miondoko ya viumbe vingine vya mbinguni yote hufanana na ni sawa sawa.
