E = mc2
So, what is this famous equation by Einstein is all about?
Well, the equation says that matter (m) and energy (E) are two forms of the same thing.
The speed of light (c) which is constant, is an enormous number.
So basically, Einstein's equation shows that a very tiny amount of matter is the same as a huge amount of energy.
The equation is a direct result of Einstein's work on the special theory of relativity.
