Hello, Duane;
Not knowing the details of Heim theory, I'll have to trust you on that one.....however, I am 'correct' about what the Tajmar report says.
It is not a simple report to understand simply because of the way it is written ....however, the results are clear....
Unfortunately Astepintime took one passage out of context and drew a faulty conclusion based on his prejudice,,,,which I notice is a very common prejudice among those who have a predisposed belief that Gen Rel. can never be wrong...and who begin trying to interpret (very unobjectively) everyone else's reports AS supporting their prejudice.
In realty this report may turn out to have nothing at all to do with 'overthrowing' GR. and may simply be a quantum effect ...which we know already has never been reconciled fully with GR anyway.
Let me paraphrase...
In this report Tajmar merely repeated earlier exper. in Setups A & B .....with similar large anomalous results .
Then in Setup C, (the part Astepintime took out of context), the Helium was RE-ROUTED (in some manner) in order that the ROTATIONAL MOTION of the helium was eliminated . It was
ONLY in this Setup C that the effect seemed to disappear.
Thus the conclusion that the Helium had to be somehow responsible for the previously measured anomalous acceleration field (in Setup A & B ).
OK?
I understand what you are trying to say, ..but this is the very reason I cannot see any value in Heim stuff,... What in the h-ll is a 'quasi-gravitational force' ....there is no such thing in standard physics....and using such undefined and ambiguous terms clearly makes them look like amateurs...
Its like me trying to describe something to you and then saying "quasi-energy" is created from a such and such.....would you understand what I was saying?
The only way for any understanding is to connect it to an EQUATION that has TERMS which are ALREADY defined and WITH A DERIVATION.
Anyway, it is this nebulous ambiquity that makes me (and most physicists) VERY skeptical.....Apparently it is that very nebulosity that allows its proponents to keep claiming (after every new experimental result) that the results verify Heim/ Drescher theory.....apparently its so ambigous that
ANY exper. results can be made to verify their theory.
For a theory to be valid it must be not only testable and but also FALSIFIABLE.
Becuase Tajmar's theoretics contained both of the above attributes it became easy to falsify his original theory AND to easily identify (what they apparently see as) a serendipitous result that may still be of great value.
Hope you understand where I'm coming from.

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).

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. Assuming we're seeing anything at all.

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:"
"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.

"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. :->

The 'fins' are in place of the rotating ring, not attached to the gyro:

In order to test our helium hypothesis, we manufactured a thinwall cup with two fins (2 crossed fins to effectively spin the liquid helium) out of Al which we mounted instead of the usual rings. We then filled the cryostat up to the top with liquid helium in order to fill the cup as well.
The gyroscope is fixed to the stationary frame of the experiment, inside a separate vacuum chamber -- hence, no gas drag:

The sensors are mounted inside an
evacuated chamber made out of stainless steel, which acts as a Faraday cage and is directly connected by three solid shafts to a large structure made out of steel that is fixed to the building floor and the ceiling. The sensors inside this chamber are thermally isolated from the cryogenic environment due to the evacuation of the sensor chamber and additional MLI isolation covering the inner chamber walls.
In other words, the gyroscope is in a vacuum, and magnetically and thermally isolated from the dewar containing the rotating sample ring (and liquid He), yet still experiences an anomalous acceleration.

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.

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?

Most probably.

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.

Because the helium is AGAIN forced to rotate....fins ROTATE the helium.
If you read the paragraph before that you will see that in the FIRST part of Setup C, the helium is allowed to penetrate upwards (without rotation).....and results in NO anomalous signal.
When fins are placed in to allow helium rotation, the effect returns.
