Copernicus' heliocentric theory was not accepted at the time for multiple reasons. Firstly, there wasn't enough observable evidence available at the time to confirm his theory. Secondly, his theory went against the widely accepted scientific theories of the time, particularly those of Aristotle and Ptolemy, who supported the geocentric model of the Solar System. Lastly, Copernicus' heliocentric theory also challenged the current religious teachings of the Church, which believed in a geocentric model based on biblical interpretations.
