Like quarks, space charges are also fractionally charged particles. But unlike quarks, the absolute magnitude of space charges is always 1/6 while that of quarks are 2/3 and 1/3. There are also two polarities (+/-) of space charges. The grouping of space charges forms the elementary particles (fermions and bosons). Analogous to the energy levels of atoms, space charges are formed by levels of existence (LOE). The LOEs determine the mass of the space charges. In order for space charges to form fermions or boson, they must acquire eight directional invariance properties. These are the top-right-front, top-right-back, down-right-front, down-right-back, top-left-front, top-left-back, down-left-front, down-left-back.
