Fakhr al-Dīn al-Rāzī (Arabic : فخر الدين الرازي) or Fakhruddin Razi (Persian : فخر الدين رازی) (1149 or 1150 – 1209), often known by the sobriquet Sultan of the Theologians, was an influential Iranian and Muslim polymath, scientist and one of the pioneers of inductive logic. He wrote various works in the fields of medicine, chemistry, physics, astronomy, cosmology, literature, theology, ontology, philosophy, history and jurisprudence. He was one of the earliest proponents and skeptics that came up with the concept of multiverse, and compared it with the astronomical teachings of Quran. A rejector of the geocentric model and the Aristotelian notions of a single universe revolving around a single world, al-Razi argued about the existence of the outer space beyond the known world.
