Copernican

My surprise reached a climax, however, when I found incidentally that he was ignorant of the Copernican Theory and of the composition of the Solar System.

The heliocentric view of the world, in which the Sun is at the centre of the universe, is also described as the Copernican system. It represents a step forward from the geocentric view of Ptolemy.

The Eratosthenian Period (3.2–1.1 aeons ago) and the Copernican Period (1.1 aeons ago to present) were times of lesser volcanism and a still lower, probably constant impact rate.

Philosophy disconnects everything and relativizes the universe. Like the Copernican model, it destroys any solid ground and sets adrift what is at rest.
