Glossary term: copernican principle

Description: This principle in its original form is an outcome of the Heliocentric (Copernican) model for the Solar System, whereby, the Earth is not at rest in a special position at the centre. Philosophically, the Copernican Principle represents a fundamental shift in the human perception of our place in the Universe. This shift was revolutionary, or perhaps evolutionary in the time of Copernicus. The Copernican Principle has been extended to = cosmology and is called the Cosmological Principle, which provides one of the key foundations of modern cosmology – there is no special location or direction within the observable Universe. Both principles are constantly being tested through a range of observations at various scales, using ground and space-based telescopes, and extensive theoretical work.
