In 1905 when Einstein presented special relativity it was treated as incomplete by the theoretical physicists of the day, because potentials were not included in the energy relation. In general relativity, a decade later, the problem with the missing potentials was not resolved. The issues were the two different potentials: electrostatic and gravitational that could not be treated in the same way. An understanding of better experiments that were long ignored was needed to define the spaces matter occupied before relativity could be integrated with quantum mechanics. The result was a new set of equations replacing the Schrodinger and Dirac equations.
