  1. Einstien.

    There are two relativity theories.

    General relativity is a theory of gravitation developed by Einstein in the years 1907–1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall is inertial motion: In other words an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and momentum within it.

    Special relativity is a theory of the structure of spacetime. It was introduced in Albert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies". Special relativity is based on two postulates which are contradictory in classical mechanics:

    *The laws of physics are the same for all observers in uniform motion relative to one another (Galileo's principle of relativity),

    *The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light.


  2. I believe that it's the result of many contributions

    Hendrik Lorenz  , Ali Moustafa Mosharafa , Jules Poincaré , Minkowski and Galileo

    but Albert Enistein put it in theoritical form

    I suggest you see this

    and If you have time see Wikipedea

    But if you need good information look for the original book  of Einstein I got it after some searches.

  3. Galileo came up with the theory of relativity. It states that there are no preferred reference frames.

    Over 300 years later, Albert Einstein added the observation that all frames obtain the same result for the speed of light, and arrived at special relativity. Some therefore mistakenly think he invented relativity. Not so.

  4. The theory of relativity refers to two theories of Albert Einstein. Of those the most famous is E=MC2, which means energy equals mass times the speed of light squared. All in all it is way to long to give a good answer to here, so check out the wikipedia article on the subject here.
