In ancient times, many people believed in a geocentric model of the solar system, where the Earth was the center of the system. During the 16th and 17th centuries, men such as Copernicus, Kepler, and Galilei theorized or found evidence that the Sun was actually the center of the solar system. However, despite convincing evidence, this idea was not accepted until some time later.

Why was this idea not initially accepted?

It is difficult to change a commonly held belief.

There was no evidence published supporting their ideas.

After a theory has been around for one hundred years, it cannot be changed.

The Sun is not large enough to be at the center of the solar system.
