Back in the 1500s, Nicolaus Copernicus posited that the center of our solar system was NOT the Earth, but in fact, the sun (heliocentrism). Galileo revived this but was charged with heresay and threatened with torture if he did not publicly recant.
It is only within the last 20+ years (done in 1992) that the Catholic Church actually exhonerated Galileo. It took them over 400 years to do this.
