“C” is different from what we have looked so far. “E” is the vast energy domain of energies, and “m” is the material stuff of the universe. But “c” is simply speed of light. Celeritas in Latin means swiftness, as light travels very fast it is given that name. It was first thought that light travels at infinite speed. Galileo was the first person to clearly conceive of measuring the speed of light.
According to his experiment he wanted two people each holding lanterns on hillsides a mile apart. They would open their lantern shutters one after the other, and then time how much of a delay there was for the light to cross the valley. The experiment was a good idea, but the technology of the time was too poor to get any clear result. A scientist Roemer after thorough research discovered that the best estimate of the speed of light was 670,000,000 mph.
Einstein discovered from Maxwell’s research that nothing can go faster than light even if you are going at 699,999,999 mph you will find that light is too fast. As this was the upper limit of speed, Einstein related mass and energy with it.
