__**Einstein's Theory of Relativity**__ The Theory of Relativity has effected modern society to the extent of GPS, Space Flight, and other scientific laws. The theory of relativity in one sentence is: Time, Space, and Gravitation, and mass all have no separation, therefore, they are all relative where we get the name The Theory of Relativity.


 * Other Scientific Laws**

Many other theories and laws have been effected or produced by the theory of relativity include time dilation or the fact that an object moving at a faster velicity will moce through time at a slower pace. Time dilation has created an unusual hypothetical scenario known as the Twin Paradox, as demonstrated in the pictures below, states that if a set of twins is born and one is shot into space at a speed near that of light and then returned home 60 years later, the space twin would seem to have aged significantly less due to time dilation.) another theory that is similar is the Lorentz Contraction which states that in a high velocity situation, space will shorten/contract so that to a bystander, the high velocity object will appear shorter in length.(Schombert)


 * GPS Systems**

Another thing effected by the theory of relativity that also happens to prove the theory of relativity is a Global Posistioning System or GPS. These systems work by communicating with an orbiting sattelite to relay coordinate and infromation. Since a satelite is moving extremely fast around the earth, taking time dilation into account, its clock will continuously be thrown off my a fraction of a second on a regular basis. Also the fact that sattelites feel less gravity than the earth, means its clock will be thrown off even more each day. These issues forced the manufacturers to make corrections so that the GPS can preform with pinpoint accuracy.(Will)


 * Final Thoughts**

The theory of relativity has effected our modern day society in many ways such as the effects of time dilation on its mission crews. another would be the other theoris such as the Twin Paradox, time dilation, and the Lorentz Contraction. Lastly, and perhaps the most prominent is The global posistioning system, which actually proves the Theory of Relativity to be true to a degree, and how their manufacturers need to account for the theory of relativity in order to make the sattelite-console information transfer as accurate as possible.
