If he heliocentric view was really “clearly observable reality”, people wouldn’t have been fooled for tens of thousands of years. What is clearly observable is that everything moves around the earth. Unfortunately, that is not reality. Reality was extremely difficult to observe. It depended on things like the retrograde motion of Mercury.
The church simply said, “Can you prove it? If you can’t prove it, don’t state it as fact, because we don’t want to reinterpret scripture for every half-baked theory.” Galileo was unwilling to follow this simple request.
When religious authority thinks they can control what a scientist can and cannot publish they have stepped out of their domain and into the realm of tyranny of the worst sort.
After Kepler's work the idiocy of epicycles within epicycles was washed away by the clear principle that all observations were much more consistent with the Earth circling the Sun.
Galileo's direct observation of the moons of Jupiter clearly circling Jupiter and not the Earth showed that the notion that all celestial bodies orbit the Earth was incorrect.
The definitive data was already in when the Church took its immoral stand on the wrong side of reality.
