I don't think that it (blame) can be pointed to the construction:
After 2 ½ years of data analysis, we have a very good understanding of the physics underlying them. We now know that the interaction of patch effects between the gyro rotors and their housings is the root cause of both, and in our September 25, 2007 status update, we described how our team has honed and utilized a technique called trapped flux mapping to dramatically improve our determinations of the polhode phase and angle for each gyroscope throughout the entire 353-day experiment period. (GPB Mission status)
As you say, it is odd that there is such a turn-about of opinion. Here are some quotes from the April 2007 article http://space.newscientist.com/article/dn11615, updating the mission:
| QUOTE | The first result from the Gravity Probe B satellite confirms a prediction of Einstein's general theory of relativity to a precision of better than 1%. "For the first time, we have seen one of Einstein's effects directly," says mission leader Francis Everitt of Stanford University in California, US.
"But lunar ranging provides indirect measurements. Gravity Probe B provides a direct measure that's unique and new."
The predictions of general relativity fall well within the probe's precision, though that might change when the team announces far more accurate results. <br>And, from the MISSION UPDATE — Spring 2008 web page: http://einstein.stanford.edu/highlights/status1.html

The subsequent SAC report noted "the truly extraordinary progress that had been made in data analysis since SAC-16 [March 23-24, 2007]" and unanimously concluded "that GP-B is on an accelerating path toward reaching good science results."
Following a peer-reviewed bridging proposal to NASA's Science Mission Directorate (SMD) and actions by Stanford and a private donor, the GP-B program has been extended at least through September 2008. <br> Maybe that private donor (and others) will step up and extend this mission.
Back to the "blame":

A time variation in the polhode motion of the gyroscopes, which creates complications in the gyro scale factor calibrations (conversion of electrical signals to angles).
Much larger than expected classical misalignment torques on the gyroscopes, attributable to “patch effect” (contact potential difference) interactions between the gyro rotors and their housings. <br> The likely occurrence of other Solar flares notwithstanding, it seems than another years worth of collecting data would be wise use of the investment so far.

QUOTE (alongman+May 21 2008, 06:21 AM) The proposed GME-2 experiment (if it works) will produce - in the rubber sheet analogy - a sustained depression whose focus is additionally displaced away from the center of the device -- accomplished by the spinning disk which interacts with the field and displaces its 'center' some distance along the disk's axis of rotation. The result in free space would be that the engine, ship and payload would 'fall' towards the low point of the depression in the rubber sheet analogy, but since the drive holds this low point away from the center of mass, a continuous acceleration will result.
Conversely, one can visualize that on the far side of the 'low point' - away from the drive device - there will be a reverse gradient as, in the analogy, the rubber sheet returns to its normal undisturbed level. So at a suitable distance away from the drive device one would experience a gravitational attraction TOWARDS the device --- providing the generation of an attractive gravity field with the many potential beneficial uses that would follow. 1) If your hypothesis holds then ground launch using GME2 would be ruled out, as attracting the mass of the Earth while being "pushed" upward would not produce a net propulsive force. Unless I misunderstand your assertions? 2) For use as a tractor beam or repulsor beam, the intensity of the "aft" field lobe would need to be reduced or somehow distorted. No point "pulling" something to you if you're moving away from it just as fast. Standard directional antennas might be able to do it however, horn antennas, etc.

TRoc....You forgot this one: GP-B scores an "F" in NASA review: http://space.newscientist.com/article/dn13...s3_head_dn13938 | QUOTE | It recommended that Gravity Probe B receive no additional funding after its current funding runs out in September.
The probe's data was unexpectedly noisy due to solar flares in March 2005 that interrupted the satellite's observations, as well as unexpected torques on the gyroscopes that changed their orientation, mimicking relativistic effects. Additional interruptions ultimately chopped the observing time into seven intervals, which reduced the precision the probe could attain.
The noisy data meant that GPB could not measure the effects as precisely as astronomers had by firing laser beams at mirrors left on the Moon by the Apollo astronauts.
It warned that the reduction in noise needed to test rigorously for a deviation from general relativity "is so large that any effort ultimately detected by this experiment will have to overcome considerable (and in our opinion, well justified) scepticism in the scientific community".
<br>So basically GP-B is being de-funded...

According to Basic Physical Laws that is "Force and Motion Laws" All forces are Repulsive and or Positive, Each Force should be treated as a Potential. A negative force can only be theoretical and or possible on paper via overlooking the fact that once a mass or potential has been divided off to else and there is nothing left so that what we refer to is borrowed mass and or potential.. We also need to refer to Potential and Kinetic Energy Laws and or the equation PE/KE=V or meters/second=change and or work. As anything less than zero is VOID when we are working with a practical model, I mean can anyone seriously imply and explain how nothing or less than nothing can do anything other than nothing? So lets start by being practical and by considering Space is with potential via it is capable of increasing and decreasing in potential and or it is capable to propagate electromagnetic waves and or if one prefers quanta of photon/s.. A Potential can only be created and or in reality increased via the experience of an opposing Velocity, before I proceed I should point out all possibilities are part and parcel of the Universe and no matter where or what part of the Universe it should be treated as a division (portion) of the Universe and each division (portion) should be treated as an open sub-system with a quanta of energy to it, mind you implied as a force and or Potential - Higgs field included if you wish to go there.. An opposing velocity should be noted - Is the direct result of previous differing Potentials having being presented to each other, being mindful a potential is merely two or more velocities departing from the experience of the other velocities creating the potential and or compression point, it also should be noted a velocity is a Potential in its self only it is with momentum to it as in implied to be electron/s and or photon/s or in a macro sense even a body large enough to be deemed as a body of mass or collection of Potentials, Importantly it is here that an opposing velocity that is before each velocity has experienced the other velocities is what most laymen including members of NASA refer to as the PERCIEVED Attraction of mass (Gravity) if that last part of my statement is unclear and or you don't believe me then seriously read and learn what is entailed for a force to be Possible and more importantly how momentum or velocity is made possible, don't take my words on it, I am sure once one understands force and Motion and or Potential and Kinetics we should be able to apply the two aspects together so that when one refers to a velocity as in a small portion of Potential availed with momentum to it, one should have a clear idea what gravity is really about.. Yes ~ Its simply the highly kinetic near vacuums potential, perhaps best imagined as countless low potentials with a velocity to it, that are actually the cause for density changes and or a Masses demise to a compression point.. Why do I mention all this? The above mentioned velocities, Err~Electromagnetic waves and or Photons with a velocity to them seems to be totally misunderstood even by the experts!..

Ones clueless professor's lead, Ask any one today and they simply wont have a clue about Gravity! AND WHY IS THIS SO!? Well simply because force and motion is not completely understood by them.. So lets once and for all consider in detail how pull and or attraction is to work, and lets attempt to have the model working in a near vacuum so that Gravities misconception can be once and for all binned and replaced with the proper model! <sigh> NUFF SAID!

The rubber sheet analogy gives one an intuitive way to understand the behavior of the gravity field.
Start with the bowling ball on the rubber sheet to represent the earth's gravity field. Then imagine yourself shrunk down that you are standing on the bowling ball earth's surface. You are at the bottom of the earth's gravity well, so imagine the rubber sheet starting at your feet and extending up and away from you at say 45 degrees. It's steepness represents the strength of the earth's gravity field, and motion away from you and up the slope is equivalent to climbing directly up out of eath's gravity well.
Place a baseball on the sheet at arms length and it will roll immediately to your feet. But if you poke the rubber sheet with a baseball bat you can perhaps form a depression that will hold the baseball and prevent it from falling to your feet. If you then artfully work the baseball bat upwards while maintaining the depression, the baseball can perhaps be coaxed to follow the moving depression in the rubber sheet caused by the baseball bat and so climb up the slope. The earth's gravity in the form of the prevailing slope of the sheet around would be unaffected beyond the small local distortion of it's field. The depression must be big enough for the ball to fit comfortably on the advantageous reverse part of the depression, that is opposite in direction to the prevailing slope around it. So one can see that for the space to launch from earth there will be parameters that must be properly balanced for a particular payload and vehicle, and sufficient power to locally reverse the gravity field.
In the case of the GME-2 device and any future drive design it seems that the position of maximum field strength must be maintained at a point in front of (above) the payload (or at least the ship's center of mass) even though the engine itself may be mostly (or entlrely) behind it. With sufficient field strength, this allows the ship to 'fall upward' off the earth's surface.
A similar process of analogy may also be applied to visualizing tractor beam applications.

With regard to GME-2, can the better informed among you say whether the effect will occur if one holds the superconducting ring stable and spins the magnet instead?
As I understand it the gravitophoton force is proportional (in some way) to the relative velocity of the material (bosons, fermions, whatever) in/to the magnetic field.

The renewed activity here sent me back to review some of the earlier Heim theory papers,... thus far Heim’s Theory of Elementary Particle Structures (Auerbach and von Ludwiger, Journal of Scientific Exploration,Vol. 6, No. 3, pp. 217-231, 1992) and Extended Heim Theory, Physics of Spacetime, and Field Propulsion (Dröscher and Hauser, 10 April 2006).
In the former work, a statement is found that the speed of propagation of gravitons in Heim's six-dimensional universe should be 4/3 of light-speed, meaning that, once a working detector is established, we should have ample warning of approaching supernovae radiation. Having just read that the mission of LIGO is to, among other things, prove that gravitational waves propogate at the speed of light, we can't expect verification of Heim's 6-D prediction to come from them. :-/
In the latter paper, there is no mention of the propogation speed of gravitons, raising the question: Does EHT back away from the gravitons @ 4/3 C statement?
Does anyone 'listening in' here have an answer to that question? Verification of this would be a real attention-getter for Heim Theory.

For more on how Tajmar results could have influenced the GP-B data, (and solar effects) see here: <br>Thanks for the link, according to the poster "Gsquare" in that thread, the DeSitter-Fokker effect of the Sun was considered (19 milliarc sec/yr).
So, the other "Solar contribution", ie. the flare, was "unlucky". But, as I indicated, it seems a little odd that they did not expect any Solar flares for the duration of the experiment?
Gsquare also had this to say:
| QUOTE | **The other modeling I would like to see (in GP- is that which would take into account the Tajmar / deMatos effect. As I mentioned to Publius some time back, the greatly enhanced gravitomagnetic field of the gyros should not influence the frame dragging precession portion of the experiment.....BUT that was ONLY considering its interaction (or lack of interaction) of a SINGLE gyroscope with the earth's gravitomagnetic field.
The problem developes when we realize there are FOUR gyros in GB-P, two spinning one direction and 2 spinning the other direction....(which was done for redundancy to cross check and make for greater accuracy in the data).
If we consider the multiple effects of 4 greatly increased GM fields of the 4 SC gyroscopes, then we have to deal with their INTERACTION WITH EACH OTHER. Surely if the gravitomagnetic field of a superconducting Gyro is enhanced as great as Tajmar experiments suggest, then the interaction of the dipole GM field of each gyro with the others must be taken into account.
Even though each gyro is magnetically isolated, it is impossible to gravitomagnetically isolate them....Gravitomagnetism is an angular momentum transferring field, the interaction between gyros of which can very possibly mimic unbalanced torque (or at least confound any modeling) of polhode / electrostatic coupling of the gyro to the frame.
<br> Since we had had no takers on the reference, I did a little digging. Here are a few papers that might contain that GPB "coincidence":
Experimental Detection of the Gravitomagnetic London Moment [ PDF ] Martin Tajmar, Florin Plesescu, Klaus Marhold & Clovis J. de Matos

Also, a couple of articles to read:
Gravity's secret [ Link ] 11 November 2006 - NewScientist.com
Towards a new test of general relativity? [ Link ] ESA News
I think that it's also important to note, that NASA did not recommend to stop funding because of the problems, per se. Just that they did not have the funds to continue "everything", and GPB did not make the cut. It's now "free-agent"; which is why I think that someone else may "pick it up". They were concerned that the results (apparently challenging some well established work) needed to be "cleaner", in order to validate the results. "Extraordinary claims >> extraordinary proof" kind of a thing; with so many problems with the data, there will be people who won't accept it.

Tajmar's experiments need no magnetic fields. But you have to keep in mind the topic of the thread I am posting in. Of cause the theory was almost not peer reviewed and so it is very hypothetical to talk about the impacts to the physics. Therefore, please, read the description of the experimental setup of GME 2 that depends on magnetic fields. I'm not going to discuss the validity of HT or EHT at the moment. I just intended to renew the discussion about the limits of GME 2. What I wanted to show is that GME 2 could be extended to be used for zero-G applications or even for levitation and space propulsion. According to EHT - if EHT is considered being applicable - the setup of such a field propulsion would be far more simpler with superconductors than using rotating plasma in a magnetic field(fermion vs. boson coupling). And my question to the sophisticated physicists was "Am I right in saying so?"

JW GME1 is what Droscher et al use to refer to the Tajmar experiment GME2 is Droscher e al's term for their proposed variant experiment.

Duane <br>Thanks , Duane, for clarifying the meaning of their use of GME1 and GME 2; I went back and re-read, and you are correct. Of course, all experimental set-ups that involve superconductors must take into account Cooper pairing, that is the whole fundamental basis for condensed matter physics....Tajmar included. However, it really bothers me that this Droscher report ignores any reference to the magnetic field interaction (in their GME 2 proposal) that will arise when a external B field is applied to a dipole (London moment) field of a rotating superconductor. (see figure 6 & 7); in the report. (they appear to be totally unaware of such an interaction): http://www.hpcc-space.de/publications/docu...Abbreviated.pdfHow can someone propose an experiment and not even take into consideration the forces that shall result from the most obvious resulting field interactions....completely ignoring them....and only including some speculative gravitational force that supposed arises from purely theoretical assumption that "photons convert to gravi-photons" ?? Furthermore, How can Droscher justify not even giving their derivation of the equation which supposely gives the acceleration force? And the eqn. they give doesn't even include the magnetic field at all!
Since the ENTIRE experimental success hinges on equation #16 (in that report), please TELL ME WHERE I can get a copy (a link) to the DERIVATION of that equation.I really don't see how everyone can be jumping onto this very simple proposal without any analysis from the perspective of standard well known physical principles.

Thanks, JW IIRC, the rotating disks in both the original and current proposed Heim experiments are not superconductive. The non-rotating coil below the disk is superconductive. The mathematics for the force creation are detailed in older papers, early 2006 and before. However, those were for the presumed fermionic pathway, which required gargantuan magnetic fields (20-60+ Tesla). I'm not sure if it carries over completely to the post-Tajmar bosonic pathway (far lower technical requirements). Links to the older papers can be found: http://www.hpcc-space.de/publications/http://en.wikipedia.org/wiki/Heim_Theory#Propulsion_physicsAnd yes, I'd like to see a complete linear review of the mathematics to date, and/or a tabletop experiment that is at least indicative and designed from the get go to identify any EHT effects.

Good explanations, Duane - you've clarified a few things quite well there. Tajmar is very interested in D&H's GME2, which he hadn't considered himself. He studied the derivation and agreed in principle, and even found some minor numerical errors which D&H will correct in some of their next papers. And just to show that Tajmar is still working with Droscher & Hauser, look at this latest paper of T et al. which again refers to D&H 's explanation as well as those of De Matos, Beck et al. - it is the first paper to make a detailed comparison with the GPB results - and shows the Tajmar mechanism could indeed explain that. http://arxiv.org/ftp/arxiv/papers/0707/0707.3806.pdfOr has this been mentioned here before?

Hugh The article is seriously flawed. As it treats a Perception as if it is some magical force that is able to violate laws pertaining to how force and motion is possible. May I point out that all forces are a potential and a potential is created via its opposing velocities, ergo all forces are repulsive! If one cares to consider opposing velocities, where a velocity is a portion of a Potential with momentum to it, hence implied to be Kinetic Energy it should be obvious what the experience of gravity really is.. Consider the following.. Let force = Newton meter Let Newton meter = height Let height = Potential Energy Let width = kinetic Energy or a time frame of work, as in seconds of time for instance" Let this symbol in the quotes "-" equal a Potential by (one Kinetic) or (one second), It may also be implied to be a "c^2" near vacuum. Let this symbol in the quotes"=" equal double the previous symbols Potential by (one kinetic) or (one second), It may also be implied to be a c^2 "NEAR Gas" or a Near Vacuum with a Photons Potential to it. Now.. Let this system in the quotes imply a small percentage of the universe "--------" we will note it's dimensions are 1 by 8, and I could imply the system is a NEAR Vacuum, I could also imply we have 8 individual sub-systems and or masses and therefore imply one M=one subsystem and or a single c^2 with a minimum potential as in M=8 "c^2" subsystems next to each other. And if we wanted our model or system to consist with a mass with double the density perhaps a photons potential or a near gas somewhere amongst it, we would need to introduce into the model opposing velocities, as in.. Force applied for one second to the right-> "---=---" <- Force applied for one second to the left, we will note our system has and is experiencing compression, in fact if we consider the Outer Near vacuum medium in our model Vs the inner Near vacuum, the inner would experience Blue-Shift while the outer would experience Red-shift, just as our universe behaves, anyway if we wish, we could point out the more opposing velocities introduced the greater the mass we could create, so lets please consider the following image, but note how the artist has depicted a serious flaw to it! User posted image: User posted imageWe can prove that the images plots and or grids are flawed by filling out the rest of the planes of grid-ding as per the artist has for one plane or we could correct the image by using just some of the suggested planes in the following image.. User posted image: User posted imageAnyway my point is all Potentials are the result of opposing velocities and the resulting stored Energy creates an increase in Potential Energy, At this point let me stress the NEAR Vacuum "SPACE" is with Potential Energy as well as Kinetic Energy and therefore should be considered to consist with stored opposing velocities, via considering where there are two opposing velocities we have a resulting potential. Also going by the fact that kinetic quanta is exchanged to Potential Quanta, via opposing momentum is cancelled out via opposing velocities, resulting as a compression point and best referred to as Blue-Shifting, and by taking another gander at the first image and by ignoring the Artists fatal error, it should be easy to imagine how a Black-Hole or any other compression point is created by what ever potentials are presenting repulsion, as far as laymen are concerned it results as a perception of a magical and or unexplained inertia towards some common point the earths core for instance, when in fact inertia is from above us via compression via the collective near vacuums repulsive potential "perceived accelerating expansion of the universe".. BTW if some physicist reading my rants, understands my above models and has enough data applied PROPERLY as per the above models with electromotive forces, they should be able to devise a method of artificial gravity... Any Questions? Then Cheers, Peter J Schoen..

If so, a major potential support of EHT just collapsed. If the "Tajmar Effect" is mistaken then so too at a minimum is the imputed bosonic mechanism. Tho the last lines of the conclusion seem to reverse that judgment: Compared to classical frame-dragging spin-coupling predictions, our signals are up to 18 orders of magnitude larger. This suggests that the observed phenomenon is new and without explanation so far. As a layman I'm misunderstanding something here. Duane

Astaprintine....you obviously read the report WRONG...please go back and re-read.

JW Hmmm... Assuming you're correct, that's actually a closer approximation of the proposed Heim experiments (GME2), both bosonic & fermionic. Mag field from a (super)conductor creating a quasi-gravitational force through interaction with a rotating insulator. No reason in principle that the insulating "rotating disk/torus" needs to be solid. Oh, reread some of the earlier papers yesterday. I reversed the "special materials" used. The "STL" version is cited as using the low-z material (preferably hydrogen), not a higher-z material. Which has obvious implications here, helium being second-best to hydrogen in the low-z category. Dropped a line to John Reed, looking forward to some feedback from both him and Hugh. Duane

Hi Duane,
Well, having skimmed through the paper (I've been busy with other things and hadn't seen it yet - thanks Greg for posting!), I see that the actual effect is a combination of material used - i.e . again they see a dependence on sample composition (Niobium, Al, etc.). but this is weaker than before. The main effect is a coupling between the rotating helium and the rotating sample, as far as i can tell - I believe that He on its own gave a signal, but much weaker.
Well, the HE nucleus is justan Alpha particle - a boson. The HE atom is still a boson, with 2 electrons added to the Alpha particle. So it's still about rotation of bosons. What I also understood was that the effect may indeed not be due to accelaeration of the disk but movement of the He - it seems that the latter has to accelerate its ang. vel. to give the effect. I must study in greater detail later.
Their conclusions:
Conclusions Anomalous signals from two different fiber-optic gyroscopes (KVH DSP-3000 and Optolink SRS-1000) were observed above spinning rings at temperatures below 30 K. Results from different configurations suggest that the origin is most probably connected to the rotating helium and not the angular momentum of the spinning source as it was suspected from earlier measurements. Our observed signal strengths are not ruled out by any other experiment up to our knowledge [17-18] and systematic effects appear to be at least two orders of magnitude below all reported measurements for the various setups. The gyro signal seems to follow the rotating ring velocity with high correlation. Compared to classical frame-dragging spin-coupling predictions, our signals are up to 18 orders of magnitude larger. This suggests that the observed phenomenon is new and without explanation so far.

Hope you understand where I'm coming from. JW Hi JW, Thanks for the skilled overview. Were GR utterly unflawed, one assumes there would be no conflict with QM and all would be hunky-dorey in the world of physics, theory complete. Any data in the report on whether the effect is some sort of pressure artifact due to rotational action of gases? As to "quasi-gravitational," poor terminology on my part. I am not an expert, and my descriptions should be treated as qualitative at best, tho I have reviewed the available sources in decent depth. I agree with you about the need for derivations. The below may have what you want. It is a moderately brief review of the asserted mechanisms. Beyond that, IMO Heim is a hypothesis at this point, not a theory, albeit moderately well developed. It should be approached and evaluated on that basis, with the assumption that parts are immature and judgment as to whether the developed aspects have merit or not. http://www.hpcc-space.com/publications/doc...RevisedSept.pdfEHT posits that there are six fundamental forces, not four. The two additional forces are gravitational in nature ("quasi-gravitational"), one accounting for repulsive dark energy ("quintessence"), and the other coupling gravitation and electromagnetism (gravitophotons). It is gravitophotons that are used to create the proposed physical effects. The gravitational constant "G" is thus composed of three terms, Gg (graviton constant) + Ggp (gravitophoton constant) + Gq (quintessence constant). Gg ~= G, Ggp ~= (1/67)^2 Gg, and Gq ~= 4*10^-18 Gg. Thus the contributions of the gravitophoton force and quintessence to the overall established gravitational constant are quite minor in magnitude. Proper manipulation of physical conditions is purported to allow the conversion of photons into gravitophotons, which can be either positive (graviton-like, attractive) or negative (quintessence-like, repulsive). As for detailed mechanisms and mathematics, (shrug), the papers are available and penetration of Christoffel mathematics is slow going for me verging on preference for painful suicide at the hands of the Marquis de Sade. Review is your choice. :| I would certainly not assert that any evidence can support the Heim hypothesis. If the "Tajmar Effect" has been shown to be mechanical, it certainly shoots down a major possible supporting argument for EHT. If however a gravitational force is now seen as emanating from the rotating helium in the test cell, in relation to the superconductive coil, and only while the helium is in motion, that does bear striking descriptive similarity to the example mechanism cited in the early papers. However, that is qualitative analysis by a layman, and not in any way conclusive. It is certainly not proof, nor an attempt to act as a booster by any means possible. I welcome anyone to tear down EHT on the basis of Edison reasoning; we will have productively learned yet another way NOT to do it (try to produce a GUT). Duane

Pardon, I did not mean to take anything out of context and certainly rereading the paper would help me understand it more detail. However, I believe we agree that the SETUP C tests that strongly suggests that it was the super chilled helium that "somehow" causes the anomalous effect. Note the test in setup C with the "FIN"s-- the effect is back. This combined with the discussion of the concern of the helium gas with the surface of the rings all led me to believe that it was a complex "mechanical" interaction between the moving helium and rings. (Note: I say moving since I can't tell from the figures how the helium is rotating with respect to the rings). In other words, no new physics just very tricky and complex classical physics and thus a very non interesting anomalous result. Sure, I might be reading this wrong - I'll reread --- but right now it still seems to me to be a face-saving paper.

"The only difference here is that THE SOURCE is apparently not simply the rotating superconductors but rather the ROTATING HELIUM...(.or possibly some interaction between the two)." Yes, but this does not mean new physics.
"Please note... neither Gen Rel. or any other theory predicts that any material (helium included) should produce such a large acceleration field upon rotation."
Well moving gas and the Bernoulli effect would be enough. But really this effect is not large it is very tiny ---look at the coupling. Any small systematic effect could mask it.
"There is no question that the effect persists ...simply look at the data (fig. 4 and 5)..its the same as the initial report....with the same anisotropic parity in the direction of rotation."
Sure and we now know it is the moving helium that 'somehow' causes it.
"The only difference is that they have now isolated the source...which appears to be connected with the rotation of helium." Agreed, but I think it will be difficult to rule out classical effects.

First of all, EHT does indeed say there are 6 forces instead of 4, with 3 of these being gravitational (no quasi- about it: unless you consider the 'normal' Newton-Einstein gravity as the one true one and the others as 'aberrations' - a question of semantics which so-called critics will leap upon: but that is merely nit-picking) .
The other point about the rotating liquid helium: Recall that liquid Helium is a composed of bosons, since He atoms are bosons, as are Alpha particles, their nuclei. THus it might well be that it is these bosons and not the Cooper pairs in the sample metal that causes the anomalous acceleration. Let there be no doubt: Tajmar et al. re-emphasise the fact that there is still an anomalous acceleration or artificial gravity. No 'mechanical' or 'gas' effect can magically cause a distance force as measured by the fiber-optic gyroscopes.

Note that Tajmar et al. say in the 2nd paagraph of the introduction to that paper:
"Recently, Tajmar and de Matos [6-8] predicted that spinning superconductors or superfluids instead of electron spin polarized materials might produce much larger non-classical frame-dragging fields in order to explain a reported Cooper-pair mass anomaly in niobium [9-10]. Other theoretical concepts were proposed supporting this conjecture [11-13]."
where Droscher & Hauser were nr. 12 of refs [11-13]. SO - Liquid He, being a superfluid, is indeed a candidate source for the effect.
Discussing setup A (He and sample rotating), they say:
"The results show that the rotation of our sample rings can indeed be seen by rigidly mounted gyroscopes at a distance once the sample ring passed a critical temperature below 30 K. At 4 K and a top speed of 420 rad/s, the anomalous gyro signal is as large as one third or the Earth’s rotation. Their behaviour can be summarized as follows: First, the gyro outputs show a parity violation between clockwise and counter-clockwise rotation (the clockwise signal is larger than the counter-clockwise signal). It is important to note that for the case of the above-ring gyros, if the gyro’s orientation is flipped, the effect sign flips as well and the large effect is only present for the same clockwise-rotating of the spinning ring. This measurement tells us that the effect seems to be rotationally symmetric and that the source for the parity anomaly does not result from the gyro itself."
No sign of evidence against an effect there - on the contrary, each new experiment only confirms the presence of the anomaly. Then they show how careful they were to exclude stray magnetic fields, gas drag, vibratons etc.:
" And third, the signal does not decay from the above to the reference position as one would expect from a dipolar-field distribution. Systematic effects were analysed in detail such as magnetic field influence, gas drag, sensor location and vibration [16]."
Finally - EHT in no way refutes General Relativity - since it is an amalgam of GR & QM in the same way as other quantum Gravity models (e.g. Loop QG), it is in fact an extension of GR.

The originally proposed fermionic mechanism asserted action on the protons and neutrons of the insulator, so it is possible we're seeing the fermionic pathway here.

Hdeasy,
Well, clearly I may not understand the experiment as well as others so please bear with me.
"Discussing setup A (He and sample rotating), they say:"

"No sign of evidence against an effect there - on the contrary, each new experiment only confirms the presence of the anomaly. Then they show how careful they were to exclude stray magnetic fields, gas drag, vibratons etc.:"
Well, it would seem to me to depend on what is going on with the He gas flow. Did its rotation also change or was it kept fixed when the gyro's rotation was reversed? Remember the effect went away 'for the standard rings' after rerouting the He flow, independent of the gyros rotation.
Yes, they might of carefully studied 'gas drag' effects but Ref 16 is before their discovery of what re-routing does. Recall that helium at these temperatures acts most strange.
Finally, putting 'FIN's on the gyros gets the effect back? What is going on here ? Am I being a simpleton here -- fins would seem to make the gyros much more sensitive to the gas flow in any new routing setup -- thus getting the effect back?
All that being said -- I agree that the conclusion is written is such a fashion to imply that the anomaly is still very important and NOT trivial. So clearly either I must not understand something or they are try to save face. Probably the former, but it would not be the first time I misunderstood something. :->

Astepintine; I think you are really not understanding what this is all about. First... As hdeasy (and Mongo) have explained....the lasers gyros are completely isolated from the moving rings or the moving gas. Second: Let me expalin what these gyros ARE....and their PURPOSE. These are laser gyroscopes and they are IN EFFECT the same as accelerometers. They are designed to measure ROTATION....if they are attached to SOMETHING rotating. But here they are NOT attached to anything moving....so their purpose is a little different. Now I think you may need a bit of relativistic understanding for the next part: In the first Tajmar / deMatos experiment (PLEASE read the report) ACCELEROMETERS were located OUTSIDE of the rotating rings and isloated from their movement. Why? The purpose was to detect what is called a "gravitomagnetic field" that may have been generated IN THE VACUUM . This 'acceleration' field is the result of a "frame dragging" field....typically caused by rotation of matter (in Gen. Rel. ) Do you understand how laser gyroscopes detect rotation? By counter rotating lasers..... (like a Sagnac gyroscope does). IF the inertial frame is 'dragged around', the laser phases are offset, producing a signal. So these are very well suited for detecting a gravitomagnetic field .... IOW, they can be used to detect FRAME DRAGGING.. IOW, any 'acceleration type' field that rotates the SPACE -TIME structure around the apparatus....(after the earth's rotation is subtracted out). Since gyros are more accurate and stable and far less susceptible to vibrational and temperature variations , etc. they can be substituted in place of the accelerometers. In this new set of experiments the accelerometers were replaced by LASER GYROSCOPES . Got it? It would really help is you learn about laser gyroscopes ..... These are NOT gyros as in the GP-B exper.

Bill MONGO Ok thanks, that clears a lot up! ! ! My misunderstanding! Although I am still probably very confused. A nice 3-D diagram might help. The gyroscope shows no gas drag but the rings might? Otherwise why use fins? Why does one see the effect when one uses FINS and not using the standard rings in SETUP C?

"I think you are really not understanding what this is all about." Most probably.
"First... As hdeasy (and Bill) have explained....the lasers gyros are completely isolated from the moving rings or the moving gas." Yes, I believe I now understand this. This is the huge point that I was missing!
"Got it?". Well probably not. I am still confused about why the effect comes back in SETUP C when the fins are used.
