Special relativity revealed that the speed of light is a limit that can be approached but not reached by any material object; it is the origin of the most famous equation in science, E = mc2; and it has led to other tantalizing outcomes, such as the “ twin paradox .”
Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to the forces of nature. [2] . It applies to the cosmological and astrophysical realm, including astronomy. [3]
Describe the experiments and scientific problems that led Albert Einstein to develop the special theory of relativity; Understand the postulates on which the special theory of relativity was based
Special relativity. Einstein’s Gedankenexperiment s. Scientists such as Austrian physicist Ernst Mach and French mathematician Henri Poincaré had critiqued classical mechanics or contemplated the behaviour of light and the meaning of the ether before Einstein.
The theory of special relativity, originally proposed by Albert Einstein in his famous 1905 paper, has had profound consequences on our view of physics, space, and time.
In 1905 Albert Einstein developed the theory of special relativity. This theory explains the limit on an object’s speed and describes the consequences. Relativity does not only apply to far-reaching and (as yet) unrealized activities like human interstellar travel.
There are really two Einstein theories of relativity. This chapter is concerned with the Special Theory of Relativity, which dates from 1905. In 1915 Einstein published an additional theory, called the General Theory of Relativity.
