Also unclear is how they generate a "gravity drive" from an electromagentic field without current science being able to define or determine what a graviton really is, except for it being the messenger particle of the force of gravity. Hard to manipulate something you cannot ascertain as of yet. (Except of course in theory...you might not have know what it is, if you know it is there...may be there thinking.)
There are four universal force...EM, the electromagnetic force, is completely seperate from the gravitaional force...though many have speculated you can use one (EM) to manipulate the other (Gravity)...and of course an inter-relationship of all those forces (and linkage) brings us back to M-Theory...do we already have an answer to unified field theory?
Maybe Dr. Hauser thinks he does...supposedly the answer lies in a mathematic tensor equation using topology (non linear geometry).
I hope this guy proves himself right.
Four universal force(s)
Gravitational
Electromagnetic
Strong (Nuclear)
Weak (Radioactive Decay)
Here's my take on what they're doing (I'm not an advocate -- before yesterday I'd never heard of Heim theory). It looks like they're taking the R4 Minkowski space from Einstein and extending it to 8 dimensions. It lets them come up with a set of metrics, for instance for the photon, W bozon, Z boson, graviton, etc. (that is, for the fundamental forces). Apparently the math also lets them come up with additional metrics, for two postulated particles that they have named gravitophotons and quintessense particles, corresponding to two additional postulated fundamental forces.
By manipulating the math it looks like they're expressing the photon metric in terms of the postulated gravitophoton metric. When they do this, it's in the form of a scalar potential, a vector potential, and an additional tensor potential (the scalar and vector potentials are reminiscent of the Lorenz force law we all know and love). The paper attempts to devise an experiment in which most of the terms cancel and only the gravitophoton component remains, which they interpret as a condition where gravitophoton particles dominate in the region of the magnetic field. Because of the properties of the postulated positive and negative gravitophoton particles, they propose that the effect should be a cancellation of the existing (Earth's) gravitational field if the strength of the gravitophoton field force is high enough.
There seems to be lots of hand-waving in the PDF, and I get the impression that a large piece is missing, that is, something detailing the fundamentals of Heim theory. This is really necessary to try to understand what they're claiming is going on, and barring that one is forced to take them on faith. Hopefully they will come out with something comprehensive that starts with basic principles and leads to their conclusions. I did a web search and there is a claim that Heim theory predicts the masses of several subatomic particles to within several decimal places of precision of experimental values, which has apparently never been done elsewhere, so perhaps this theory holds promise.
