Albert Einstein developed a theory about the relationship of mass and energy.
The formula, E=mc[2], is probably the most famous outcome from Einstein's
special theory of relativity. The formula says energy (E) equals mass (m) times
the speed of light (c) squared. In essence, it means mass is just one form of
energy. Since the speed of light squared is an enormous number (186,000 miles
per second)[2], a small amount of mass can be converted to a phenomenal amount
of energy. Or, if there's a lot of energy available, some energy can be
converted to mass and a new particle can be created. Nuclear reactors, for
instance, work because nuclear reactions convert small amounts of mass into
large amounts of energy.
