What does E = mc^2 actually mean?
Let's start at the very beginning, A very good place to start. When you read, you begin with A-B-C. In science, you begin with E and MC:
E, a quantitative property.
M, the mass of something there.
C, a speed as fast as light.
2, that stands for something squared.
So, if mass and light combined-
Square, and equal energy,
Then, in relative spacetime-
That will bring us back to E equals MC (squared).
That's all in a musical by Rodgers and Einstein of course.
