Man and Our Amazing Sun

Since ancient times man has observed the sun and the sun has played a large role in the development of culture. Stonehenge is one example. It was built over 4,000 years ago in England and still stands today. People once thought that it was used to tell what time of the year it was. When that theory was tested, the researchers found that to be very inacurate. Now, it is thought to have been used in an ancient celebration

From ancient times until just a few hundred years ago, it was strongly beleived that everything in the universe, including the sun, revolved around the Earth. Aristotle first put into writing that the Earth was the center of the known universe. Later, Ptolemy gave mathematical credence to Aristotle's theory . It was not until Copernicus wrote that the Earth revolved around the sun and Kepler proved that ,mathematicaly, using Brache's observations that this belief became no longer credible. In those times before Kepler, people also thought that the Earth was flat. It was hard even then for Christopher Columbus to prove to the world that the Earth was round, so it was really a challenge for people to accept that the Earth was not the center of the universe.

Through the discoveries that many scientists have made, we now know more about our galaxy, solar system and the universe. Eventhough our sun is not the center of the universe, or our galaxy, it still has a big impact. We know through experience and studies that the light from our sun travels millions of miles through space. The Earth is 93 million miles away from the sun, and we still get temperatures that are above 100 degrees Fareinheight. Some of our most advanced satelites have trouble penetrating the intense light that our sun gives off. This is proof of how powerful and amazing our sun is.
