E = mc^2 actually refers to particles without motion, plus the energy of motion
With the energy of motion, you can have mass of 0, and still have energy
Applies to many different areas of the universe
E = mc^2: A recipe for converting matter to energy and vice versa - requires energy to make such a conversion, and a lot of energy
Energy doesn't take up much space, takes up more space when converted into matter
