**__Theoery of Relativity__**
====The theory of relativity is two different theories created by Albert Einstein to help explain how things such as how gravity works in general physics. The two branches are general and special relativity. General Relativity provides a unification of newtons laws with special relativity. Special relativity is the theory on how spacetime is constructed. These theories are generally accepted although not proven in the scientific community.====

====Although not proven most scientics accept that there is no absolute frame of reference in the universe (Howstuffworks 6). This is taken from Einsteins theory of special relativity. It explains that there is no one place in the universe that is completely stationary. That means that everything is moving compared to something else.====

====It is also universally accepted that when travelling near the speed of light time slows down. This was an idea first put forth by Einstein in his theory of special relativity. This idea is proven by the Lorentz Transforms. This test is preformed by taking two attuned atomic clocks, leaving one on earth and bringing another to a high altitude moving at a fast speed. After the test is completed the clock that was at the higher speeds is no longer attuned but is behind the clock on earth. This proves the clock slowed down at a higher speed.====



Another idea of Einstein that was proven by the Lorentz Transforms was the idea that objects moving at high rates of speed actually contract in length. This works if you have a stationary person (remember frames of reference) observering an object at a high rate of speed. The object is actually perceieved to become shorter in length.



In conclusion, many parts of the theory of relativity have been proven or are widely accepted in the scientific community and impact the world because of its acceptence.

Zavisa, John. "How Special Relativity Works." 01 April 2000. HowStuffWorks.com.  29 January 2009. This is an alright source for the theory of relativity, it is not as easy to understand as my other article. It also has lots of backround info, but the site has not been updated as recently.

Theory: Special Relativity (SLAC VVC)." __SLAC Public Website Server__. 29 Jan. 2009 . This article seems like a good unbiased source of info for the theory of relativity and has lots of backround info with it. It is a reliable updated source.
