who showed that our universe is heliocentric the planets of the solar system revolve around the sun
Heliocentrism It was not until the 16th century that a geometric mathematical model of a heliocentric system was presented, by the Renaissance mathematician, astronomer, and Catholic cleric Nicolaus Copernicus, leading to the Copernican Revolution. In the following century, Johannes Kepler elaborated upon and expanded this model to include elliptical orbits, and Galileo Galilei presented supporting observations made using a telescope.
Heliocentrism Early in the 11th century Alhazen wrote a scathing critique of Ptolemy's model in his Doubts on Ptolemy (c. 1028), which some have interpreted to imply he was criticizing Ptolemy's geocentrism,[33] but most agree that he was actually criticizing the details of Ptolemy's model rather than his geocentrism.[34] Abu Rayhan Biruni (b. 973) discussed the possibility of whether the Earth rotated about its own axis and around the Sun, but in his Masudic Canon, he set forth the principles that the Earth is at the center of the universe and that it has no motion of its own.[35] He was aware that if the Earth rotated on its axis, this would be consistent with his astronomical parameters,[36] but he considered it a problem of natural philosophy rather than mathematics.[31][37]
