Actually it's [tex]E = mc^{2} [/tex] and it says that the energy of an object (E) is equal to the mass (m) of the object multiplied with the squared speed of light ([tex]c^{2} [/tex]). This theory says that mass can be turned into energy and energy can be turned into mass. This is one of Einstein's theory of relativity.

Theory of relativity and E = mc²

Main article: History of special relativityEinstein's "Zur Elektrodynamik bewegter Körper" ("On the Electrodynamics of Moving Bodies") was received on 30 June 1905 and published 26 September of that same year. It reconciles Maxwell's equations for electricity and magnetism with the laws of mechanics, by introducing major changes to mechanics close to the speed of light. This later became known as Einstein's special theory of relativity.
