General Relativity and EM - Heim Theory

[Antiphon]

Some questions in the Theory Development forum seem to be revolving
around the topic of formulating electromagnetism as a geometrical theory
along the same lines as gravity in General Relativity. (I couldn't post this in
that forum for some reason.)

This was apparently done 50 years ago but not widely known by a
man named Burkhard Heim. Remarkably, this theory is the only one which
seems to reproduce the mass spectra of the known subatomic particles
from first principles, and no he was not a crank. His theory is not widely
known because he was severely handicapped and did much of his (mostly
unpublished) work in seclusion.

A good overview is at: http://en.wikipedia.org/wiki/Heim_theory

For the conveneince of the forum goers, I have collected together some of
the papers referenced in the overview. These papers are good background
for the Heim Theory but are somewhat speculative and geared toward
the possible application of Heim theory to exotic propulsion systems.

Keep an open mind and let's hear some feedback from the experts on
the forum.
