Definition of E = mc2: Implicit Concepts of Physical Units

Abstract

Mass-energy equivalence (E = mc2) states that latent energy can be converted into an equivalent amount of mass and vice versa. However, the ulterior motives of each constituent have not yet been understood because the present definitions and analyses of E=mc2 are mostly restricted to the phenomenological theory of results. The meaning of mass creation in space can be interpreted as the division of given space. In other words, the energy quantity differences in constant space can occur during, before, and after mass creation, satisfying the following equality: space energy as a universal set = space energy as a complementary set + space energy transformed into mass as a complementary set. Accordingly, based on invariable space energy, our research shows and defines a series of energy-maximum, energy-quantity, and energy-level relationships in E = mc2 via physical units such as electron, mass, and velocity.
