Final answer:
During the Scientific Revolution, body and universe concepts stemmed from Greek thought, proposing indivisible particles called 'atomos' or continuous division of elements. Enlightenment thinkers critically reassessed these notions, paving the way for modern science.
Step-by-step explanation:
At the beginning of the Scientific Revolution, accepted ideas about the body and universe heavily relied on classical thought. Ancient Greek philosophers like Leucippus and Democritus proposed that all matter was composed of indivisible particles they referred to as atoms. Other thinkers like Aristotle believed in the four-element theory, stating that matter consisted of earth, air, fire, and water and could be divided infinitely.
However, it was during the Enlightenment that traditional beliefs were critically assessed, leading to the modern understanding of science and the universe. The idea of atoms laid the groundwork for our current understanding, though the notion has evolved significantly to include the knowledge that atoms themselves can be divided into even smaller particles.
