The full equation is E squared equals mc squared squared plus p times c squared, where p represents the momentum of the object in question.
E, or energy, which is the entirety of one side of the equation, and represents the total energy of the system. m, or mass, which is related to energy by a conversion factor. And c2, which is the speed of light squared: the right factor we need to make mass and energy equivalent.Jan 23, 2018

And that constant happens to be the speed of light squared.
Also in 1905, which has been called Einstein's annus mirabilis (amazing year), he published four groundbreaking papers, on the photoelectric effect, Brownian motion, special relativity, and the equivalence of mass and energy, which were to bring him to the notice of the academic world, at the age of 26.
Now we're getting to the c² 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.Apr 7, 2021
It's taken more than a century, but Einstein's celebrated formula e=mc2 has finally been corroborated, thanks to a heroic computational effort by French, German and Hungarian physicists.Nov 20, 2008
Light has no mass so it also has no energy according to Einstein, but how can sunlight warm the earth without energy? Light indeed carries energy via its momentum despite having no mass.Apr 1, 2014
On paper at least, he showed that while E=mc2 always holds true for inertial mass, it doesn't always for gravitational mass. “What this probably means is that gravitational mass is not the same as inertial,” he said. According to Einstein, gravitation is a result of a curvature in space itself.Jan 3, 2013
