Earth around the Sun theory
In a survey of the sky, WISE found more brown dwarfs farther from the sun than it did nearby. In this image of our astronomical back yard, shown from a the view of 30 light-years from the sun, brown dwarfs within 26 light-years from the sun are circled, with objects in blue having been previously identified, while red circles indicate new brown dwarfs revealed by WISE.

Earth Centered theory
Photo by: rgbspace Viewpoint: Yes, early scientists believed that what appeared to be movement around Earth by the Sun and other entities was, in fact, just that. Viewpoint: No, later scientists such as Nicolaus Copernicus and Galileo correctly realized that Earth moves around the Sun, not vice versa, and thus cannot be the center of the universe. It is easy in our human nature…

What was the heliocentric theory?
The heliocentric theory argues that the is the central body of the and perhaps of the universe. Everything else (planets and their satellites, asteroids, , etc.) revolves around it. The first evidence of the theory is found in the writings of ancient Greece. Greek philosopher-scientists deduced by the sixth century B.C. that is round (nearly spherical) from observations that…

Copernicus epicycles
Nicolaus Copernicus (19 February 1473 – 24 May 1543) was a Renaissance mathematician and astronomer who formulated a heliocentric model of the universe which placed the Sun, rather than the Earth, at the center. He is generally considered to be the initiator of the Scientific Revolution. His most developed model of the system was set out in on De revolutionibus orbium coelestium…

Geocentric view: Earth-centered view. (600BC – 150 AD) Came from the belief that God created humans at center and everything moved in perfect divine circles. Earth was a sphere that remained motionless at center of the universe Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn orbited earth in circles Stars traveled around the earth on a celestial sphere (transparent and…
