The Concept

Mass is just a super-concentrated form of energy. Because the speed of light ($c$) is enormous, a tiny amount of mass ($m$) multiplied by $c^2$ equals a massive amount of energy ($E$).

1 gram of matter contains as much energy as the atomic bomb dropped on Hiroshima (~15 Kilotons of TNT).
