Hallo Jork,

Deze vergelijking 'zegt' wat er gebeurt als massa (m) wordt omgezet in energie (E). In de formule zie je ook nog de lichtsnelheid staan (c).

Of zoals Einstein het zelf uitlegt:

"It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing -- a somewhat unfamilar conception for the average mind. Furthermore, the equation E is equal to m c-squared, in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa. The mass and energy were in fact equivalent, according to the formula mentioned before. This was demonstrated by Cockcroft and Walton in 1932, experimentally."

Maar je kunt beter luisteren naar Einstein zelf:
