136 The Secret History of the World
We believe that Einstein was following a path that was later to prove very
fruitful. Einstein, however, was somewhat nervous about this idea, but he followed
it anyway, writing in his paper:
If Kaluza’s attempt is a real step forward, then it is because of the introduction of
the five dimensional space. There have been many attempts to retain the essential
formal results obtained by Kaluza without sacrificing the four-dimensional
character of the physical space. This shows distinctly how vividly our physical
intuition resists the introduction of the fifth dimension. But by considering and
comparing all these attempts one must come to the conclusion that all these
endeavors did not improve the situation. It seems impossible to formulate Kaluza’s
idea in a simple way without introducing the fifth dimension.
We have, therefore, to take the fifth dimension seriously although we are not
encouraged to do so by plain experience. If, therefore, the space structure seems to
force acceptance of the five dimensional space theory upon us we must ask whether
it is sensible to assume the rigorous reducibility to four dimensional space. We
believe that the answer should be “no”, provided that it is possible to understand, in
another way, the quasi-four dimensional character of the physical space by taking
as a basis the five dimensional continuum and to simplify hereby the basic
geometrical assumptions.[…] The most essential point of our theory is the
replacing of …rigorous cylindricity by the assumption that space is closed (or
periodic).[…] Kaluza’s five dimensional theory of the physical space provides a
unitary representation of gravitation and electromagnetism. […] It is much more
satisfactory to introduce the fifth dimension not only formally, but to assign to it
some physical meaning. 60
The reader should note that when considering field theory, it is necessary to
differentiate between 1.) Pure field theory such as gravitation, and electrical and
magnetic fields and 2.) Quantum field theory. Fields such as electromagnetic fields
and gravitational fields are continuous and spatial while quantum fields are
quantized, broken into discrete sections of particulate substance or energy. The
basing of a theory of psi on a gravitational field rests partly on the fact that
gravitation is not subject to the maximum velocity of light because it doesn’t
travel, but is structural. Evidence from Vasiliev and others suggests that psi is also
independent of the velocity of light.
However, general relativity has obliged science to abandon the “action at a
distance” idea, causing the ‘distance force’ to be abandoned, and has placed
gravity under subjection to a maximum velocity. Nevertheless, Margenau has
suggested that general relativity ought to be regarded as a ‘formal’ principle such
as the Pauli Exclusion Principle. In this case, gravitation would be non-energetic
