The Special Theory of relativity is an acknowledged physical theory that revolutionized advancements in the relationship between space, and time. The theory is one of the most interesting discoveries that are still used today in science fiction movies such as Star Wars, and Star Trek through the use of black holes, and time travel due to it’s astonishing results, and it occurrence at speeds close to the speed light, which can be appealing to a wide range of audience. This was a harvest from six years of extremely handwork by Albert Einstein. Einstein used resources that were widely available to the public due to his economic constraints. It wasn’t until 1905, when Einstein finally had finished and published his discoveries, and gatherings of previous discoveries from other scientists regarding the special theory of relativity. It wasn’t until the 19th century when Albert’s discoveries were put on a dependable experiment by Maxwell adding to the legitimacy of Einstein’s discoveries. The special theory of relativity is still in use today in modern technological devices such as the GPS, as well as sub-microscopic particle interactions, and motion of stars and galaxies, and cosmology. The Special theory of relativity’s first postulate of principle relativity, also known as Galilean Principle of Relativity states that, no physical measurement can distinguish one inertial frame from another, meaning that the laws of physics apply in all situations, at all times, and in all places. The Special theory of relativity’s second postulate states that the speed of light in vacuum is the same in all inertial frames, regardless of any motion of the source. This means that the speed of light is essentially the same in vacuum under all conditions... ... middle of paper ... ...damentally the decrease in length observed by a person from stationary reference frame on the object that is in motion, and the more the speed relatively to the observer the shorter the length of the object is observed. L = L0((1 - v2/c2))1/2 where: L = the length measured by the "other" observer L0 = the length measured by the observers on reference frame v = the speed of the object c = the speed of light in a vacuum L = 6.5 m v = .55c L0 = ? 6.5 = L0×(1- .55c2/c2) 6.5 = L0×(0.45) L0 = 5.5/(0.45) = 12.2 m As to conclude the Special theory of relativity is one of the breakthroughs, and can be considered the masterpiece of Einstein’s work. Its principles are bases of technological devices that are still use today, such as the GPS. It has two basic principles that contribute to further conclusion regarding time dilation, length contraction, and mass increase.
