Great! You bothered to ask about the theory of my favourite scientist! E=mc2 means that the amunt of energy that can be released from a matter depends on the amount of substance destroyed. with this, scientists made the first atomic bomb. E is the energy in joules, and c is the speed of light in meters per second.

what others posted above, about the relation between mass and energy. it also implies the possibility of a nuclear bomb, because it states that mass can be turned into energy, and vice versa. this equation was the basis for the Manhattan project, as well as all other nuclear efforts. nuclear bombs cause so much destruction because when a neutron collides with a radioactive substance, like enriched uranium, the uranium breaks apart into three pieces: 2 "smaller" elements, and whatever remains of the enriched uranium after the two smaller elements form. this last piece of mass turns into energy by the equation e=mc^2.
it also seems to imply that mass and energy are simply different representations of the same thing, which could be superstrings, a small particle of energy.

It explains the energy difference (called binding energy) due to the mass defect (difference between the mass of the individual components that make up an atom and the mass of the atom). This mass difference multiplied by the speed of light squared is proportional to the amount of energy released during fission of heavy nuclei.
This formula is used by nuclear power plants to calculate the amount of U-235 depleted based on the amount of power produced in the reactor.

Conversion of energy into mass.
The deep connection Einstein discovered between energy and mass is expressed in the equation E=mc² . Here E represents energy, m represents mass, and c² is a very large number, the square of the speed of light.

The physicist and humanitarian took his place beside the great teachers with the publication of Relativity: The Special and General Theory, Einstein’s own popular translation of the physics that shaped our “truths” of space and time.
LOTS of information at this web page for you!

Energy = Mass * Speed of Light ^2
Its a universal fact now, instead of theory. It has been tested and proven with flight, space travel, etc. How he came up with it is more intriguing than what it means, since it is so common now.
The speed of light is a known constant. Square it, times your mass, and that is the energy you need to "fly" or become weightless.......

Energy produced is equal to the mass lost times the square of the speed of light. Even if minute loss of mass occurs, enormous energy would be produced becuase of the speed of light squared multiplier. That is the basis of nuclear power. Nuclear fission results in loss of mass and therefore release of energy.

Fundamentally, it means that our "human" perception that there is a physical difference between "matter" and "energy" is actually an illusion caused by the way we are able to interpret reality. If you make a piece of "something" move fast enough, it "becomes" energy....

Energy=Mass x Speed of light; squared

WHEN there is a nuclear reaction in which mass is destroyed, this formula indicates the amount of energy that is created from that mass.
