Skewon Exotic Propulsion?

The skewon w is poised right on the cutting edge w = - 1/3 of what is needed for WWD.
If the skewon energy tensor could be tweaked to have w more negative than - 1/3.
Note the basic idea here is that in Einstein's 1915 GR in the weak field slow speed limit the full field equation

Guv(Geometry) = -(8piG/c^4)Tuv(source)

Limits to the Newtonian Poisson eq.

Grad^2V(Gravity) ~ (G/c^2)Trace{Tuv} = (G/c^2)(Energy Density)(1 + 3w)

w = Pressure/Energy Density

For ordinary matter at slow speed v/c << 1

w ~ 0

For real photons w = +1/3

For skewons w = - 1/3 hence Trace{Tuv(Skewon)} = 0

So NO GRAVITY is induced from the untweaked isotropic skewon field of Hehl et-al.

But FOR ALL vacuum zero point fluctuations ZPF of ALL quantum fields universally, Lorentz invariance in the LIF + EEP imply w = -1 ON THE DOT EXACTLY.

Therefore, in Newtonian limit, easy to visualize classically

Grad^2V(gravity) ~ -2(G/c^2)(ZPF ENERGY DENSITY)

This means that an ISOTROPIC POSITIVE ZPF ENERGY DENSITY ANTIGRAVITATES (UNIVERSALLY REPULSIVE) from its dominating NEGATIVE PRESSURE. This is DARK ENERGY.

Similarly a NEGATIVE ZPF ENERGY DENSITY will GRAVITATE ATTRACTIVELY (UNIVERSALLY) and this is DARK MATTER when in COMPACT CLUMPED SOURCES.

NO REAL PARTICLES HERE TO BE DETECTED. This is ABSOLUTE BENDING OF SPACETIME BY THE ABSOLUTE AMOUNT OF ZPF FROM ALL FIELDS. This is UNLIKE CASIMIR FORCE OF QED, which is the RELATIVE DIFFERENCE between SPACE WITH NO PLATES and SPACE WITH PLATES. That effect is completely IRRELEVANT to anything important in the METRIC ENGINEERING OF WWD and WORMHOLE TRAVEL.

The ZPF is NONLOCALLY COHERENT but LOCALLY INCOHERENT (RANDOM) as are ALL Einstein-Podolsky-Rosen EPR correlated states. That is, in my theory of emergent macro-quantum gravity, at 0 deg Kelvin in vacuum of space

4D Supersolid Density = ZPF Density + Higgs Field Density

The Higgs Field Density is NONLOCALLY COHERENT and it is also LOCALLY COHERENT out of which we get the LOCAL CURVED TETRAD FIELD that is Diff(4)scalar

B(P) = (Effective Planck Lattice Length)'d'(Goldstone Phase of Higgs Field at P)

P is the LOCAL DIFF 4 INVARIANT "Einstein local coincidence", i.e. Diff(4)orbit of manifold points x.

OK Skewon Field has w = -1/3 so it is not as good as ZPF which has w = -1.

Skewon Field DOES NOT WARP SPACE-TIME! It's gravity neutral so it is NO GOOD for WWD, but it still may be good for non-geodesic Corum EM stress-propulsion pulling g-force.

An anti-symmetric stress-energy source tensor permits propellantless propulsion I seem to recall. This may related to Jim Corum's idea. However, remember there are two kinds of propellentless propulsion:

1. Geodesic (e.g. Paul Hill's "acceleration field", G. Trimble's "G-engine")
i.e. Weightless Warp Drive WWD) pulling no g-force in sharp-turn maneuvers.

Here M drops out of the problem. M = mass of ship.

2. Non-geodesic, i.e. pulling g-force like James Woodward's scheme, Shipov's scheme, & Puthoff's scheme.

i.e. VdM/dt term without actual ejection of propellant.

I suspect a hypothetical skewon field engine will still be non-geodesic with g-force and not WWD.

WWD is what we want of course.

Hehl is a serious theorist. Thanks for the tip.

"The skewon field contributes non-trivially to the electromagnetic energy. In particular, it induces an asymmetric electromagnetic energy-momentum tensor, which can cause specific gravitational effects in the Einstein-Cartan-Maxwell system (with skewon)."
