Except it gives the wrong answer for Mercury.
By using a strict analogy with Maxwell's equations, they get the coefficient in front of "magnetic" effects wrong, as seen in Wald,
General Relativity. The result is their prediction of Mercury's orbit is wrong.
Kindly see from arXiv (sorry for this kind of reference, this is from my paper):

This shows clearly that the linearized theory of GR is not perfectly isomorphic with electromagnetism...
... which shows de Matos and Tajmar are on the wrong track.
The same essential mistake is here:
http://arxiv.org/abs/gr-qc/0304104The point being unless you use the linearized equtions of GR, there is no way
a priori to conclude that both v_G = c and the proper coefficients in the Graviational analogue of the Lorentz force. Thus de Matos and Tajmar depend on linearized GR to get as far as they do, thus they predict the same as Einstein because they have used Einstein's math and their own theory which rests on no postulates. Having stolen Einstein's math without insight, they are left with a sterile theory.
Compare

rpenner,
I like the simple approach. If the Sun & Moon affect the Oceans; then what you've suggested regarding magma flows gives a fairly sound explanation to gravitation variance seen in instances of such alignment.
Zarkov,
>> the change in velocity of the Voyager spacecraft ?
Could this be due to an increase in interplanetary dust?...would slow down the probe a tad.

As far as I know, the Voyger anomaly is an anomaly because all KNOW factors that could play a part have been addressed to no avail.
What I posted is the reason. Jupiter is an energy emitter thus the field spin velocity of the Sun at that distance is increased, thus increasing the gravity value of the Sun at that distance. (drawn form a mathematical analysis)

Can someone offer a promising explanation to the Allais effect (see link)?
http://www.economist.com/science/displaySt...tory_id=3104321
The Allais Effect is due to Sun's gravitational field variation that in turn induces a varying gravitomagnetic, the varying gravitomagnetic field creats, in gases and liquids, Foucault masse currents (Eddy masse currents)

Thanks to all who are contributing to this discussion. I'm still digging into these subjects, but I came upon another question - always easier than answers :-)
Regarding the ejection of matter from galaxies via jets (see:
http://antwrp.gsfc.nasa.gov/apod/ap041211.html ) and a novel paper concerning anti-gravitational effect of spinning masses (see
http://arxiv.org/pdf/gr-qc/0505099 ) Could the paper be explaining the observed effect? Could the paper also explain the repulsive gravitational force, currently being ascribed to dark energy?
Thanks!
