Question

C=mc2 What does the C mean?

Answer 1

which c ?

Answer 2

Actually, it's E = mc2, and E stands for energy.

Answer 3

E = mc^2  is likely the equation you refer to.

In Einstein's theory of special relativity, it means that there is an equivalence between the Energy and the Mass.

Mathematically, it means that the total energy (E) of a body is equal to the mass of the body (m) times the square of the speed of light (c).  (remember that c, or the speed of licht is a constant).

Answer 4

The equation is E = mc^2.

E is energy

m is mass

c is the speed of light in a vacuum

Answer 5

E=mc2
