This famous image of Earth is named the Pale Blue Dot.

From a secular perspective, that is all Earth is—a tiny bit of rock and water in a vast and meaningless universe of chance.

The heliocentric view pictures the sun as motionless at the center of the solar system with all the planets, including the earth, in motion around it.

Geocentricity is a conceptual model of the form of the universe which makes three basic assertions about the nature of the earth and its relationship to the rest of the universe. A geocentric model of the universe seems first to have been formalized by Ptolemy, the famous Greek astronomer who lived in Alexandria around A. This model was generally accepted until Copernicus published his heliocentric model in 1543.

Since it is convenient to compare other orbits to Earth’s orbit, we refer to this distance as one astronomical unit, or AU.

At one AU, it takes Earth one year to complete an orbit.

Yes, even scientists have biases and favorite theories.

No one, not even a scientist, likes to see a theory that has cost a great deal of money and much of one's personal time and effort, go up in smoke.

The conclusions that are drawn from the evidence are often and have often been very much exaggerated to fit personal beliefs and biases.The theory of special relativity holds as a basic assumption that the speed of light will always be the same everywhere in the universe irrespective of the relative motion of the source of the light and the observer.The ability of special relativity to successfully explain many non-intuitive physical phenomena which are manifested by atomic particles when moving at speeds greater than about one-tenth the speed of light seems to corroborate this assumption.Newton (1643-1727) was then able to explain why Kepler's laws worked based upon his famous law of gravity. Many attempts were made to prove that heliocentricity was true and geocentricity was false, right up until the early 1900's. The most well-known of these is the Michelson-Morley experiment which was designed to measure the change in the speed of light, due to the assumed motion of the earth through space, when measured in different directions on the earth's surface.This tremendous progress in understanding resulted in almost universal acceptance of heliocentricity and rejection of geocentricity. The failure of this experiment to detect any significant change played an important role in the acceptance of Einstein's theory of special relativity.

  1. I have received dozens of these emails over the last few weeks, both directly from scammers and as submissions from site visitors. Will send some of my pictures To some, more naive recipients, the messages may seem genuine since, unlike most spam email, they do not contain a link to a website and do not appear to be selling or promoting anything.
