The speed of light squared is a colossal number, illustrating just how much energy there is in even tiny amounts of matter. A common example of this is that 1 gram of water -- if its whole mass were converted into pure energy via E=mcÂ² -- contains as much energy as 20,000 tons (18,143 metric tons) of TNT exploding.ow we're getting to the cÂ² part of the equation, which serves the same purpose as the star-on and star-off machines in The Sneetches.. The c stands for the speed of light, a universal constant, so the whole equation breaks down to this: Energy is equal to matter multiplied by the speed of light squared.
The speed of light is the upper limit for the speeds of objects with positive rest mass, and individual photons cannot travel faster than the speed of light. This is experimentally established in many tests of relativistic energy and momentum.
