Why did his theory cause dissatisfaction and panic in the church at that time?

Because people at that time were confused by "science at that time" and thought that heaven and earth were round and misunderstood the description of the world in the Bible, the church put forward a theological view based on the theory of heaven and earth in order to conform to science. Bruno was opposed to this kind of science at that time, which made the church dissatisfied, especially the Catholic church always thought that the Pope was right, and Bruno's remarks would affect the authority of the Pope.

In addition, during Bruno's period, western science began to develop, and most famous schools were run by churches. The church did not oppose science, but was misled by the accepted science and inertial thinking at that time and treated Bruno cruelly. It is wrong to teach such behavior. We should learn from it.

Therefore, it proves that we must treat the Bible correctly and not misunderstand it because of inertia thinking or "science". How many former "science" were overthrown by later "science"? We shouldn't be superstitious about what authorities say. Only the Bible mentions God, saying that even if heaven and earth are abolished, God's word will not change. Only the Bible is pointed by God, saying, "A word cannot be added or deleted." .

Only the Bible is correct. It's just that people's own understanding is wrong, just like color blindness doesn't know what color it is when looking at red.
