The Heliocentric Theory: Copernicus and Kepler
The Heliocentric Theory: Copernicus and Kepler is a skill on Pengi from Lesson 1: The Scientific Revolution in Pengi Social Studies (Grade 7).
Key Concepts
For over a thousand years, everyone believed the Geocentric Theory —that the Earth was the unmoving center of the universe. In 1543, Polish astronomer Nicolaus Copernicus shattered this view with his Heliocentric Theory , proposing that the sun stood at the center and the Earth revolved around it.
This idea was radical and dangerous. Later, German astronomer Johannes Kepler used math to prove Copernicus right, but he corrected one detail: planets do not move in perfect circles, but in oval shaped paths called Ellipses . This mathematical proof made the heliocentric model undeniable to scientists, even if the public remained skeptical.
