Thanks for the complement, Prof. However, to answer some of the concerns raised, I believe from one of Einstein's famous principle (the mass-energy equivalence principle) and from his formula, E=mc², that anything that has mass also has an equal amount of energy vice versa. Meaning that the equivalent energy of an object can be calculated as the mass × speed of light, c². The formula also implies that an object at rest having a considerable amount of mass has a very amount of energy internally.
