Look closely at the image above to understand what was considered “true” for centuries. When men like Galileo (1564-1642) began to question conventional wisdom, they faced opposition and vilification. As the “father of modern science,” Galileo’s advocacy of a heliocentric model (the Sun as center) positioned him in direct conflict with religious authorities. His books were banned, he was accused of heresy and forced to recant his views. For many years he lived under house arrest.

The idea of a geocentric universe seems laughable to those of us looking back from our 21st century perspective.
