A. The theory that the Sun is the center of the universe
Explanation:
Unquestionably, the Heliocentric Revolution is among the most important scientific breakthroughs ever. It involved the systematic replacement of the more recent Heliocentric Model, which accorded the sun global priority, with the earlier Geocentric Model, which put Earth at the center of the universe. From a philosophical standpoint, this would also alter how Western philosophers would need to redefine our significance in the cosmos. By casting doubt on their alleged infallibility in the sciences, it would politically undercut the influence of established religion, which supported the Geocentric model to a great extent.
