    This formula equates mass and energy as part and parcel to each other (x amount of mass = x amount of energy)

    Logical it seems at frist glance, but i wonder when i look at atoms colliding which produce gigantic amounts of energy way out of proportion to their mass.

    is the equation which tells us the total amount of energy a given mass of matter has contained within it.

    For example, a 1 gram piece of matter has a total energy of 9x10^13 J:


    so



    This is roughly equivalent to the yield of the Hiroshima bomb, by the way.

    However, this formula is used for mass at rest- a slightly moderated formula is used for the total energy of matter in motion:



    This formula actually predicts the existence of antimatter, as shown by Dirac- using matrices, which is quite ironic as he set out to remove the negatives (antimatter) from the equation.

    Following the above line of thought, Then a black hole with its compressed mass must contain energy beyond measure thereby rendering it's mass noll and void.

    How on Earth did you come to that conclusion, then?
