E=mc2 | what is?

This simple formula pieced together by Albert Einstein represents the correlation of energy to matter. It essentially means that space, time, mass and energy are all related, and that [c] is the universal constant that ties them all together.

Here is a breakdown of the meaning of each letter of the formula:

  • [E] represents energy measured in joules.
  • [m] represents the mass of a specified object.
  • [c] represents the speed of light, which moves at 186,282 miles (299,792 km) per second within a vacuum.

What this equation is basically saying is that energy and matter are interchangeable, and within our universe there is a set amount of energy and matter. In other words, energy regularly changes form to matter and matter likewise changes into energy. Furthermore, the formula stipulates that energy is equal to matter multiplied by the speed of light squared.
