E=mc² - What does it mean ?

E=mc² is an equation discovered by Albert Einstein that describes the relationship between mass and energy. It means that energy (E) and mass (m) are two forms of the same thing and can be converted into each other. The equation states that the energy (E) of a particle or object is equal to its mass (m) multiplied by the speed of light (c) squared (²). In simpler terms, it means that even a tiny amount of mass can be converted into an enormous amount of energy. This equation is the basis for nuclear energy and the development of atomic bombs.
