It is, perhaps, expecting rather too much to hope that the answer to this question be given within the limited scope of 'Answers'! To begin with, there are two theories of relativity: the Special and the General. To grasp an understanding of these theories the questioner is referred to the book written by Einstein himself and called, in fact,
"Relativity: the Special and the General Theory".
Like many things, there is no short cut to understanding - you just have to get down to the job!
By the way, Einstein's theory is NOT simply e = mc^2 !!!

Albert Einstein's theory of relativity, or simply relativity, refers specifically to two theories: special relativity and general relativity.
Special relativity considers that observers in inertial reference frames, which are in uniform motion relative to one another, cannot perform any experiment to determine which one of them is "stationary". This is known as the principle of relativity.
General relativity is a geometrical theory which postulates that the presence of matter "curves" spacetime, and this curvature affects the path of free particles (and even the path of light). It uses the mathematics of differential geometry and tensors in order to describe gravitation without the use of the force of gravity. This theory considers all observers to be equivalent, not only those moving with uniform speed.
The equation E = mc2 was derived as a consequence of the special theory of relativity.

There are two theories, general relativity and special relativity and they are linked to the concept that light in a vacuum travels at a fixed velocity, 'c'. One of the strange features is that no matter where the measurement is made from, light always travels at velocity 'c' and therefore if light is emitted from a fast moving object, its velocity will not change but its wavelength will which is known as the Doppler effect. This is why in space most galaxys, which are moving away from us are red shifted in that the wavelength of the light coming from them is measured to be longer than would be expected while Andromeda, which is moving towards us is blue shifted.

ok. I don't think E=MCsquared is not the theory of relativity.
i think the best way to describe the theory is that time is relative to the speed at which a object is traveling. i.e the faster you go the slower time passes.
and by the way energy is equal to the total amount of mass destroyed by the speed of light squared. Mass cann't be destroyed. but at a atomic level some mass is and the energy provided is big because the speed of light is so big. and its squared.

Get 'Einstein's Universe' by Nigel Calder. It throws some light on the subject.

E=mc^2
or E = mc squared
What it means is that the total Energy (E) in a substance is equal to the mass (M) multiplied by the speed of light squared (C^2).

energy equals mass x the speed of light squared
