Heliocentric

adj. considering the sun to be the center of the universe

In astronomy, heliocentrism is the theory that the sun is at the center of the Universe and/or the Solar System. The word is derived from the Greek (Helios = "Sun" and kentron = "Center"). Historically, heliocentrism is opposed to geocentrism and currently to modern geocentrism, which places the earth at the center. (The distinction between the Solar System and the Universe was not clear until modern times, but extremely important relative to the controversy over cosmology and religion.) Although many early cosmologies speculated about the motion of the Earth around a stationary Sun, it was not until the 16th century that Copernicus presented a fully predictive mathematical model of a heliocentric system, which was later elaborated by Kepler and defended by Galileo, becoming the center of a major religious dispute.

Heliocentric The heliocentric system was universally known in antiquity as a part of the teaching of the Mysteries, and certain eminent sages of those archaic times even taught it more or less openly, among them Confucius in China, Greek philosophers, Egyptian priests, and Hindu astronomical and other writers. Pythagoras veiled the heliocentric theory under the teaching that the planets (and the sun) revolved around a mysterious central fire, invisible to us, but whose light was reflected to the earth by the sun.
At the same time, practically all antiquity adopted the geocentric point of view for public dissemination of their ideas. Secrecy may have been their reason; or they may have wished to represent the mechanism geocentrically for convenience of use, since they and their readers lived upon the earth and not upon the sun. The same secrecy is not necessary today because we no longer recognize the harmony of nature and the universal correspondences: we can be trusted with the key because we have mislaid the lock.
