Einstein's most famous equation relates mass and energy: E=mc^2 . So, if you're not matter (mass), you're energy. Which, by the way, is how we make energy in fusion reactions, converting mass to energy.
Fission too. I personally have both mass (more than I want) and energy (Not as much as I would like).
Ahh so that's what it means. I was trying to think of what sounds like "energy" and could also fit in this sentence.
