Document Summary
Task 2 - through the lens of new science. The geometric model of the universe in the sixteenth century. Earth as the center of the universe. The length of the year depends on the movements of the sun and the earth relative to each other. Six wandering stars (moon, venus, mercury, mars, jupiter, saturn) Two distinct regions: (1) from the earth up to the moon (sub-lunar region) and (2) from the moon to the end of the universe (super-lunar region) Nothing exists outside the universe, not even space. Aristotle proposed he called their movements in small cycles epicycles: ptolemy also proposed those cycles for bigger stars, this geometric model was in use until the seventeenth century and well adopted by the church. The sun as the center of the universe, the mercury, venus, the earth (orbited by the. Moon), followed by mars, jupiter, saturn and the sphere of immobile stars.
