Just so that guy can get brainliest, ill just tell you something random!
On Sep. 27, 1905 Albert Einstein, came up with his equation. E=mc2, it is used to find how much energy is in a mass or object. E stands for energy, M stands mass, c2 stands for, times the speed of light squared, so you would say it like this, energy equals mass times the speed of light squared.
I hope this taught you something!
