Why did church leaders feel so threatened by Galileo's support of the heliocentric theory?

The church leader's felt threatened because then the people who went to the catholic church would believe Galileo's theory, protest against the church and do the same as what martin luther did in the past which was to protest against the catholic church and preach his own believes to the people of rome.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
