By the utilization of the Theory of Relativity, the world has been able to advance in the feilds of technology, and technological research related to cosmology. To understand how the implication of the theory of relativity affects technology you must under stand the basic theory. In November of 1919, Albert Einstein, confirmed that light rays from distant stars were deflected by the gravity of the sun in just the amount he had predicted in his theory of gravity, general relativity. General relativity was the first major new theory of gravity since Isaac Newton's more than 250 years earlier (Lightman). Many of the predictions of general relativity, such as the bending of starlight by gravity and a tiny shift in the orbit of the planet Mercury, have been quantitatively confirmed by experiment. Two of the strangest predictions, impossible ever to completely confirm, are the existence of black holes and the effect of gravity on the universe as a whole (cosmology). General relativity may be the biggest leap of the scientific imagination in history (General Relativity). Unlike many previous scientific breakthroughs, such as the principle of natural selection, or the discovery of the physical existence of atoms, general relativity had little foundation upon the theories or experiments of the time. No one except Einstein was thinking of gravity as equivalent to acceleration, as a geometrical phenomenon, as a bending of time and space. Although it is impossible to know, many physicists believe that without Einstein, it could have been another few decades or more before another physicist worked out the concepts and mathematics of general relativity. ** Einstiein's Theory of Special Relativity: **
 * __The Theory of Relativity__**
 * General Relativity:** Space and time depart from the usual rules of geometry when they seem to be curved by the presence of a gravitational field, according to Albert Einstein (Lightman).

Einstein's Special Theory of Relativity predicted that time does not flow at a fixed rate: moving clocks appear to tick more slowly relative to their stationary counterparts. But this effect only becomes really significant at very high velocities that app roach the speed of light (Lightman).


 * The Modern Aplication of Relativity : **

In the decade after its publication in 1916, Einstein's Theory of General Relativity led to a burst of experimental activity in which many of its predictions were vindicated. These predictions were encapsulated in a series of field equations that laid the foundation for all subsequent research into relativity and partly for modern cosmology as well. The mathematics behind the Einstein Field Equations not only presented a huge challenge to solve, but also led to seemingly bizarre consequences, particularly those of black holes and gravitational waves (General Relativity). At the time they were concieved, both were dismissed by many experts as mathematical flaws. It remains to be seen whether either truly exist. One example of how modern day physicist are testing einstiens laws is through experiments. An Earth satellite named Gravity Probe B is putting Albert Einstein's general theory of relativity to the test. The satellite is measuring two parts of Einstein's predictions by assessing how the presence of Earth warps space and time, and how Earth's rotation drags space and time. Building Gravity Probe B required fundamental breakthroughs in a variety of technologies to ensure this experiment could be performed. The probe mesured frame dragging//,// which is the effect of Earth's rotation on space and time. Einstein had predicted that very large objects in space would distort time and space as they spin, like a tornado. Frame dragging has not been measured previously because the effect is so small that technology previously could not record it. This use of technology helped prove the thoery proposed by einstien, by using technology that in his time would not be avalible. The theory of relativity has allowed the United States to advance in the fields of technology. In result has kept the Unites States in the now and to progress in the worlds eyes.

//This website provides the most basic information needed to understand the theory of relativity. The article is credible because it is backed by the organization of PBS. The author is also credible because of his credentals. I would have to say that this article could use the authors point of view or hi oppion on the subject to shown how others feel on the subject. Over all i found this site to very usefull.//
