The geocentric model, during which planet Earth is the center of the universe and is circled by the sun and all of the planets, had been the accepted cosmological mannequin since historical occasions. A geocentric mannequin of the universe appears first to have been formalized by Ptolemy, the well-known Greek astronomer who lived in Alexandria round A.D. Ptolemy’s mannequin envisioned every planet moving in a small circle, the middle of which moved along a big round orbit in regards to the earth. This model was generally accepted until Copernicus revealed his heliocentric mannequin in 1543. It was also through the 4th century BCE that Plato and Aristotle would create works on the geocentric universe that would secure its place because the predominant cosmological theory. According to Plato, the Earth was a sphere and the stationary center of the universe.
By the 16th century, this mannequin was gradually superseded by the heliocentric model of the universe, as espoused by Copernicus, and then Galileo and Kepler. Unfortunately, these explanations did not account for all the observed behaviors of the planets. Most noticeably, the dimensions of a planet’s retrograde loop were typically smaller, and larger, than anticipated. To alleviate the issue, Ptolemy developed the equant – some extent close to the center of a planet’s orbit. To an observer standing at this point, a planet’s epicycle would at all times appear to maneuver at uniform velocity, whereas it will appear to be shifting at non-uniform velocity from all other locations. The Scientific Revolution, which took within the sixteenth and 17th centuries, was a time of unprecedented learning and discovery.
Geocentric Orbit
He also said that the Earth spinning on its axis, rotates as soon as every day and makes a full revolution around the Sun in a year. Copernicus believed that the Sun was located close to the center of the universe. It was this middle of the universe which influenced these bodies and brought on them to revolve. This principle is called the heliocentric or sun-center concept of the universe. Copernicus began work on his major work, “On the Revolutions of the Celestial Spheres,” which he didn’t complete till 1530. However, it was not published till 1543, just before Copernicus died.
Not lengthy after Copernicus, Johannes Kepler refined the heliocentric mannequin in order that the planets moved around the Sun in ellipses , not circles . The geocentric model labored properly, by explaining why all the celebs appear to rotate around Earth once per day. The mannequin additionally defined why the planets move in a different way from the celebs and from each other. The geocentric model was according to planetary parallax and was assumed to be the reason why no stellar parallax was noticed.

To do this he discards Aristotle, Copernicus, Galileo and even Einstein also. He made correspondence with NASA, but NASA does not need any moot debate concerning the anti establish theory of Mr. Paul. He is rebuked by nearly all and seldom will get any help for preaching his anti set up concept. But this octogenarian nonetheless writes and preaches his concept with firm belief that in the future the world will recognise him absolutely. Among Catholics, Christoph Clavius (1537–1612) was the main astronomer within the sixteenth century.
