Ptolemy to Copernicus
The Copernican revolution is the scholastic transition from teaching the earth is fixed in the centre of the universe to suggesting and then teaching the sun to be fixed in the centre of the universe.
Ancient religious doctrines had been stating or were interpreted as specifying that the earth is fixed in the centre of the universe.
In 1543 Nicholas Copernicus published a book. In rebellious contradiction, the book was about the earth being a planet in motion around the sun.
Around 1600 Galileo Galilei devised a physical explanation of why the earth and the other planets are orbiting the sun. Coupled with a balance between a compulsion towards the sun and a theoretical motion at a right angle to the compulsion, the explanation involved planetary motion being a perfect circle around a fixed sun.
In the early 1600's Johannes Kepler published three laws of planetary motion. The laws stated that the path's of the planets around the sun were elliptical, that the speed of an individual planet relative to the sun varied with the inverse of distance from the sun and that the average speeds of the planets squared relative to the sun varied with the inverse of distance from the sun.
The works of all three of these moving earth believers stated a belief about the sun being fixed in the centre of the universe.
In the late 1600's Sir Isaac Newton published a book. The writing included a marriage between Galileo's physical explanation of circular planetary motion and Kepler's elliptical discernment of the same motions. And there our academia (link) accepts the revolt against the fixed earth as concluded.
Sometime in the twentieth century the sun was telescopically ascertained to have a superior speed around a galaxy than what the planets have relative to the sun.
A Copernican revolution just to do with successive modern scholars saying past scholarship was stupidly wrong about a fixed earth is a finished and successful revolution.
As a revolution boasting of a successful understanding of planetary motion at its heart, the Copernican revolution is an abject failure.
The problems centre on Galileo starting his understanding of planetary motion from fixed sun and ascending planetary motion misconceptions. When the fixed sun error is removed, the ascending error likewise vanishes. In its place is a beginning of an understanding of the inner workings of the interwoven trajectories the sun, earth, moon and other planets are following within the galactic motion of the sun's inverse square law.
