Nicolaus Copernicus's scientific ideas regarding the universe and specifically the idea of heliocentrism were at odds with the generally accepted ideas of his time. It was difficult for people to accept these new ideas, made even more difficult by the Catholic Church's powerful opposition to them for some time.
the ideas would prove all knowledge to be wrong
Because they felt it contradicted and called into question the literal truth of the Bible.
People were afraid to believe Copernicus's ideas because they challenged the long-held geocentric model, which placed Earth at the center of the universe, a view that was supported by religious doctrine and widely accepted by society. They feared that accepting the heliocentric model, which posited that the Earth orbits the Sun, would undermine their understanding of the cosmos and contradict biblical teachings. Additionally, the lack of observable evidence at the time made it difficult for many to accept such a radical shift in thinking.
Copernicus was reluctant to publish his ideas because he knew that the church would oppose him, so he was scared of being kill. this is why copernicus was reluctant of publishing his ideas
