"In so many and such important ways, then, do the planets bear witness to the earth's mobility"
- Nicolaus Copernicus
About this Quote
Nicolaus Copernicus was a 16th century astronomer who proposed the heliocentric model of the universe, which placed the sun at the center of the universe instead of the earth. In this quote, Copernicus is recommending that the planets in the planetary system offer evidence of the earth's movement. He is saying that the planets are witnesses to the fact that the earth is not stationary, but remains in fact moving around the sun. This idea was revolutionary at the time, as it opposed the commonly accepted geocentric model of the universe. Copernicus' quote is a testimony to his revolutionary work and his desire to challenge the status quo. His work laid the foundation for modern-day astronomy and helped to usher in a brand-new period of scientific discovery.
