E=mc2 is an incorrect format to write Einsteins equation for the theory of special relativity. The correct way to write the equation when the hypertext capability is not possible is to use ^2. Thus, the correct way to write the equation is E=mc^2. (ESMC) Rest Energy=Rest Mass*Speed of Light (3.0*10^8m/s)^2 Derived by Einstein and is the fundamental equation that explains mass->energy conversion.
