  In 1945 Einstein concluded that [1]: "The present theory of relativity is
based on a division of physical reality into a metric field (gravitation) on
the one hand, and into an electromagnetic field and matter on the other hand.
In reality space will probably be of a uniform character and the present theory
be valid only as a limiting case. For large densities of field and of matter,
the field equations and even the field variables which enter into them will
have no real significance.". The dichotomy is resolved by introducing a complex
Randers metric with a real valued scalar field and complex valued vector field,
providing a unified mathematical framework for gravitation & electromagnetism
for which the resulting theory's predictions agree with General Relativity; to
leading order in the gravitational constant. Hence, the related experimental
results validate both theories; and the former theory's metric solutions are
free of spurious singularities, because its stress-energy tensor includes the
energy & momentum for the gravitational field; like e.g. Maxwell's
stress-energy tensor contains the electromagnetic field.
