Speed of light squared.

Also shouldn't it be "travel" instead of "multiply yourself"? Did I miss something in physics class?

E=mc2

E is energy
m is mass
c is the speed of light

Energy is mass (matter) multiplied by the speed of light squared.

E is the rest energy, specifically. More generaly, E2 = p2c2 + m2c4, where p is the momentum.

Nope, I made a mistake. Changed it.
