I would like to know whether matter is energy? Does Einstein's formula, E=MC^2, prove that matter is nothing more than energy... all the atoms, the table in front of you, the views from your window, and the air you breathe are just different configurations of the one fundamental property: energy? Immediately after the big bang there was just energy, right? Everything else came later... from energy. So, perhaps matter can’t be destroyed, but simply converts back to a less dense form of energy? What do you think?
