In Einstein's mass energy relation E=mc2 why velocity of light is used and never ordinary vel..

Answer / sajad ahmad mir, department of

If we shall introspect Einstein's first paper on relativity, we find that the speed "c" is involved, not because we considered light instead of some other energy form, but because "c" is the speed at which time becomes, in a sense, equivalent to space. The fact that "c" is also the speed of light in a vacuum is coincidental. Einstein would have found the same relation between mass and energy even if he had considered energy emitted in a form other than light, although it might have made the math more difficult.
