What non-astronomical scientific explanation became possible due to the Copernican Revolution?

Expert Answers

One good topic might be the change in scientific thinking from religion-based to secular-based. Many old scientific theories drew from the religious beliefs of the day, including a real, tangible heaven above the clouds where spirits took physical form and a real, tangible hell below the surface of the earth where demons tormented the wicked. The studies and essays of Copernicus stayed away from the unverifiable religious aspects and focused on only theories that could be proved by evidence. This led to a scientific revolution based on provable evidence, not untested theory, which remains vitally important in science and medicine to this day.

Tides could not be explained scientifically before the Copernican Revolution, and indeed were not really understood until quite a bit later. Ironically, the first explanations of tides offered in the wake of the publication of De Revolutionibus were incorrect, though they were rooted in the new understanding that the earth revolved around the sun. Galileo and some other scientists thought the tides were the result of the oceans sloshing about as the Earth moved. Isaac Newton was the first to show that lunar gravity was the main force causing tides, though some Greek thinkers had proposed it long before.

Well, one such thing is global and planetary gravity. This was, of course, identified by Sir Isaac Newton, yet indirectly involves Copernican astronomy. Newton's discoveries about Earth's gravitational pull--which explained something that could not be explained before the Copernican Revolution--later allowed him to understand gravity in the solar system and to confirm Keplar's discovery of the elliptical shape of planetary orbits. While the second phase of Newton's gravitation discoveries relate to astronomy, if you focus on the key factor of gravitation, you see that astronomy is only indirectly related and not centrally related to Newton's new explanations of the laws of motion.
