We have already observed that matter and energy are two different manifestations of one and the same cosmic entity, instead of being two different entities. Matter instead of being immutable was energy in a frozen state, while; conversely, energy was matter in a fluid state. The liberation of energy in any form - chemical, electrical, or nuclear - involves the loss of an equivalent amount of mass.
