Trial of Galileo

The trail of Galileo was about Galileo getting arrested for agreeing with Copernicus theory of the sun being the center of the universe and not the earth . He was sentenced to trial after agreeing with that theory because of the churches believing that the center of the universe was earth and not the sun, during those times you couldn't oppose to the churches judgement so he was arrested. Galileo was able to find out that the theory through a telescope and it showed him that the earth was the one revolving because the sun doesn't rotate it stands there, so he believed in Copernicus theory and this was called heliocentric.

Geocentric was the theory that earth was the center of the universe and everything else revolved around it. Geocentric started before heliocentric was approved, heliocentric was approved by the church in 1664. So the church believed in geocentric up until 1664 when it was approved that the earth and everything around it revolved around the sun.
