The conventional interpretation of relativity in terms of space–time is a special case of a general concept which can be extended to charge and gravitational mass. When defined in terms of a particle interaction model, charge and mass become coupled relativistic components of an invariant generalized charge. Electromagnetic and gravitational forces are interpreted as relativistic components of an invariant unified long-range force between particle pairs. The result is a linear model which yields electromagnetism, gravitation, Mach’s principle, and the principle of equivalence.
