The Copernican Revolution At the beginning of the 16th century, Nicolaus Copernicus challenged the geocentric model and proposed that the Earth and other planets revolve around the sun. Who disproved the geocentric theory of universe? Due to Church control of medical training Physicians and medical students tried to make new discoveries fit into the older theories, rather than experimenting to explain the discoveries. Why was there little change in medieval medicine?įinally, there was a lack of progress in medicine during the middle ages because of a lack of scientific understanding.

In modern calculations, the terms “geocentric” and “heliocentric” are often used to refer to reference frames. Vedic Astrology uses both geocentric and heliocentric models in the genesis of its principles. The eighth sphere carried the fixed stars, all at the same distance from Earth. Each planet had its own sphere and moved in perfect circular motion. The medieval cosmos was sensibly organized, structured within seven concentric, transparent layers. Such a universe did not exist in the Middle Ages. What was astronomy like in the Middle Ages?
