Link between Allais Effect and General Relativity’s Residual Arc during Solar Eclipse

The purpose of this article is to establish a relation between two gravitational anomalies: one that has attracted part of the scientific community, the Allais effect that occurs during solar eclipse; the other, noticed but forgotten by the whole scientific community, the General Relativity’s residual arc of the curvature of rays of light in the solar gravitational field during the same eclipse. There is a systematically observed deflection about 10% larger than the theoretical value of General Relativity, which coincides with the “eclipse effect” found by Maurice Allais, thrown aside because it upsets the established truths. These corresponding anomalies were never explained by any theories and turn out to be new gravitational physics.


Preliminaries
Based on the equivalence principle, Einstein revealed a deep relation of gravity to the geometry of spacetime. General Relativity (GR) has undergone an impressive series of confirmations mostly regarding "strong" fields. But in "weak" fields where GR does not distinguish from the Newtonian limit, there are unexplained phenomena like galaxy rotation curves, the Pioneer anomaly. There is little direct evidence that conventional theories of gravity are correct on large scales.
Despite all the success of Newtonian gravity and GR on the scale of the solar system, data of unique precision collected for the last two decades by satellite-based telescopes covering all frequencies and digital image processing gave a Journal of Modern Physics number of results where these theories run into problems, such as the unexpected secular increase of the Astronomical Unit or the abnormal change in acceleration for flybys of spacecraft. We emphasize the scientific aspect of peculiar movements exhibited by an anisotropic paraconical pendulum at the time of a solar eclipse in 1954.
The aim of this article is to establish a relation between the abnormal deviation of the pendulum (Allais effect) during this solar eclipse and the observed residual arc of the curvature of the rays of light in the solar gravitational field (GR) during the same eclipse. Both gravitational anomalies were never explained by GR or by any other theories and it raises question about their nature. Our approach is as follows. In Section 1, we describe the gravitational deflection of light by the Sun during solar eclipses insisting on the fact that many observations gave a deflection 10% larger than the theoretical value during eclipse experience. We present from the outset the Allais effect, first reported in 1954 by Maurice Allais, which is an anomalous precession of the plane of oscillation of a paraconical pendulum during a solar eclipse. In Section 2, we make a mathematical link between the unexpected turn that the pendulum took during the eclipse, changing its angle of rotation by 13.5˚, and the about 10% arc's deviation observed during the same eclipse experience. Although it is not the task of this paper, we also speculate on modification of Einsteinian gravitational mechanics and a discussion mentions briefly that these anomalies turn out to be new gravitational physics including "antigravity". In Section 3, the fact that an exact agreement between theory and measurements has been obtained by radio interferometry, but has never been obtained by eclipse technique, indicating a genuine insufficiency of Einstein's theory during eclipse. In Section 4, we discuss two manners to experiment the behaviour of the gravity: measure the angle of deflection of light and measure the delay time of signals. In Section 5, we show three possible cosmological consequences of the Allais effect linked to GR's residual arc during total solar eclipse. Conclusion in Section 6: during the eclipse, the unexplained excess of arc of general relativity would be consistent with the abrupt deviation of the oscillation plane of the Allais pendulum; for these two phenomena, the currently accepted physical theories offer no explanation for this slight deviation from gravitational laws, which suggest a new physics.

Many Observations Gave a Deflection 10% Larger Than the Theoretical Value of General Relativity during Eclipse Experience
The first test of Einstein's prediction was the apparent bending of light as it passes near a massive body [1]. This effect was conclusively observed during the solar eclipse of May 29, 1919, when the Sun was silhouetted against the Hyades star cluster, for which the positions were well known. It was mainly made through the initiative of the British astronomer Eddington. He was stationed on an island off the western coast of Africa and sent another group of British scientists to Brazil. Their measurements of several of the stars in the cluster showed anywhere between three-quarters and one and one-half times the general relativistic prediction: many observations gave a deflection 10% larger than the theoretical value. The deviation between theory and measurements is too high to be only due to errors of observation [2] [3].
Even if there is no doubt that GR is nearer the truth than the value obtained from Newtonian mechanics or any other theory so far proposed, even if radio interferometry now replaced the eclipse technique bringing an almost exact agreement between theory and measurements (which has never been obtained by eclipse technique), this deviation during eclipse indicates a genuine insufficiency of Einstein's theory.  [6]. During the eclipse, M. Allais put in evidence an unexpected disturbance of the effect of Foucault. At the exact onset of the eclipse, the plane of the oscillation got up abruptly of 4.5˚.

Allais Effect; An Experience of Great Precision
Twenty minutes before the maximum of the eclipse, it reached 13.5˚ to decline slowly until an abnormality of 1˚ at the end of the phenomenon. This unexpected large scale excursion in the angular plane persisted throughout the length of the eclipse, a total of 2.5 hours of observations from eclipse start on Earth's west limb to end on the east limb. Both before and after the eclipse, the pendulum experienced normal rotation, the Foucault effect, of 0.19˚/minute. M. Allais was not looking for any effect here [6].
He got similar results when he later repeated the experiment to a much lesser degree during a solar eclipse on October 2, 1959 (the amount of the solar surface eclipsed in Paris was only 36.8% of the surface eclipsed in 1954). Like in the first case a well-defined anomaly was detected in the motion of the paraconical pendulum: its plane of oscillation shifted abruptly. Both were partial eclipses in Paris, the point of observations. Currently accepted physical theory offers no explanation whatsoever for this phenomenon. His finding raises new questions about the nature of such phenomena.
Attempts to confirm Allais's observations upon the behavior of a pendulum during a solar eclipse have met with varied results: some experiments have confirmed the presence of anomalies, while some yielded ambiguous results, and others detected nothing unusual. However none of these trials used a paraconical pendulum according to Allais's design (hangs from a special joint that permits free rotation around the vertical and it can track the Earth's rotation); nor did the experimenters follow Allais's operational procedures or ask his advice on design of the experiments.
Most of this kind of experiments had been performed using other sorts of pendulums or with Foucault's pendulum which gives spectacular effects. Even if they are close, there are essential differences between the Foucault pendulum and the paraconical pendulum with anisotropic support. The paraconical pendulum is short, can turn on itself (capable of rolling in all directions upon a plane horizontal surface), was observed without discontinuity while Foucault pendulum is long, connected to the thread which supports it and has never been observed without discontinuity for the previous experiments. Although difficulties are inherent to a short Allais pendulum, and its movement is a complex phenomenon, difficult to analyze, as long as the pendulum oscillation remains flat, the movement in azimuth of the pendulum oscillation plane is reduced to Journal of Modern Physics the Foucault effect. The experiments of the paraconical pendulum with anisotropic support include totally the Foucault effect.
The deviation of the plane with regard to the plane corresponding to the Foucault effect, at most twenty minutes before the maximum of the eclipse, entailed increases of angular speeds corresponding to the fast variations of azimuth observed. In his book Anisotropie de l'Espace [7], who is dedicated to the analysis of the eclipse effect in a more general context, M Allais quotes: "we can finally notice that the fast variations of azimuth observed from 11:20 am to 12 am and from 12:20 am to 1 pm correspond to angular speeds of the order of 6.2 × 10 −5 and 7.9 × 10 −5 radian per second which are respectively 1.13 and 1.43 times the Foucault effect (that is 5.5 × 10 −5 radian per second in the latitude of Saint-Germain's laboratory). The strengths involved in the noticed disturbances are thus of the order of magnitude of those who intervene in the Foucault effect". This deviation due to the eclipse is interpreted as a kind of antigravitation. While for other pendulums (without free support) the antigravity will manifest itself by a change in the direction of rotation of the plane of oscillation and a lower angular speed of rotation (such as the torsion pendulum of Saxl and Allen in 1970 [8] which leads to the same conclusions as M. Allais), it will manifest itself in the case of the paraconical pendulum by a greater angular speed within the framework of a deviated plane.
The eclipse effect was again observed during the eclipse of the Sun on October 2, 1959. Later, at the University of Jassy (Romania), during the eclipse of the Sun on February 15, 1961, a sudden deviation from the oscillation plane of a Foucault pendulum was observed. The pendulum had oscillated in the same plane until the moment of the deflection. An experiment carried out in China during the 1973 eclipse seemed to confirm an Allais effect, but the experiment was not very conclusive because the protocol did not exclude many biases. Another experiment concerning the eclipse effect was carried out in Mexico City during the eclipse of July 11, 1991. After the maximum of the eclipse, a decrease in the rotational speed of the plane of oscillation was observed. During the total solar eclipse of August 11, 1999, the Allais effect was studied in Bucharest, using two Foucault pendulums. On the occasion of the eclipse, NASA (National Aeronautics and Space Administration) proposed a program to observe the effect. Several universities and laboratories around the world have participated in this program, coordinated by Dr. David Noever, but no in-depth analysis of the results was published. At the same time the phenomenon received the denomination of "Allais effect". Observations in Zambia and Australia between 2001 and 2002 also show anomalies. Eight gravimeters and two pendulums were deployed across six monitoring sites in China for the solar eclipse of July 22, 2009. Although one of the scientists involved described in an interview having observed the Allais effect, no result has been published in any academic journal [5] [6].
Observations of the Allais effect are rare and rather contradictory, not only because of the rarity of such eclipses, but also because no rigorous experimental protocol has been followed. The sometimes ambiguous experimental results Journal of Modern Physics mean that the veracity of the Allais effect remains controversial within the scientific community.
Regarding the experimental results for the eclipse experiment, let's say that since the total solar eclipse of May 29, 1919, proclaimed as the triumph of Einstein's theory, measurements of the deviation of light by the Sun were performed at a number of total eclipses. Although the measurements were difficult, the effect was very close to the predicted magnitude which is double the value obtained from Newtonian mechanics. But exact agreement between theory and measurement has never been achieved. The average of the observations made during eight eclipses between 1919 and 1960 gives a figure of 1.97 for the deviation. This figure, although considered to be one of the proofs of relativity, is higher than the number predicted by the calculation and in a proportion greater than the experimental errors. Several physicists seem to estimate that a deflection 10% greater than the theoretical value is due to observation errors. Rather, we think that this is a real insufficiency of Einstein's theory, and the connection we have made between the Allais effect and the arc residue only strengthens our understanding.
To establish a link between the Allais effect and the anomaly of the arc residues of General Relativity during total solar eclipses, we will not take into account the unexplained regularities of lunisolar periodicity discovered by M. Allais to examine only the sudden and unpredictable disturbance that occurred during the solar eclipse of June 30, 1954, when the Moon interposing itself between the Earth and the Sun acted as a screen against gravity. We will perform the unorthodox calculation which follows by treating the paraconical pendulum as if it were a simple pendulum.

Gravitational Acceleration during the Disturbance Due to the Eclipse
Let us take a simple pendulum in Paris (49˚N), which can be considered to be a point mass suspended from a string or rod of negligible mass, and suppose this resonant system with a single resonant frequency is with a free anisotropic support. For small amplitudes, the period of such a pendulum can be approximated by ( ) We notice a decline of the gravitational acceleration: 9.4548 m/s 2 instead of 9.8094 m/s 2 [9].
A decrease of the gravitational acceleration is equivalent to a longer range of the radius. We know that 9.8094 m/s 2 apply to the Earth's radius 6.3776 × 10 6 m ( ) ( ) The radius is 118,481 m (6.49608 × 10 6 m − 6.3776 × 10 6 m). This implies, during the disturbance due to the eclipse, an addition of 118.481 km to the Earth's radius, which gives a gravitational acceleration of 9.4548 m/s 2 in Paris.

Parallax
The solar parallax in general is the difference in the apparent position of the Sun as seen from the Earth's centre and a point one Earth radius away, i.e., the angle We will suppose that during the eclipse the centre of the Sun is the theoretical apparent position of the star. We already know the distance Sun-Earth which is 1.495 × 10 11 m. S is the centre of Sun and the angle ASE is the horizontal solar parallax. Because this angle is so short, we can confuse, without sensible error, the Earth radius r with the arc AE of 8.80 arcseconds (or 8.80''), which is part of a circumference with centre the centre S of Sun and for radius the length d, average distance between the two centres.
The length of arc AE, compared with the entire circumference, is given by the The arc AE, or the parallax angle 8.80'', is equivalent to the Earth radius 6.3376 × 10 6 m, and to a gravitational acceleration of 9.8094 m/s 2  . For the gravitational acceleration of 9.4548 m/s 2 at most of the disturbance of the eclipse, corresponding to a radius being 6.49608 × 10 6 m, we shall obtain the pa-

Value Calculated by General Relativity
The value calculated by the theory of relativity of the angle of deviation of light by the Sun is (G is the universal constant of gravitation; c is the speed of light; M S is the solar mass and R S is the Sun's radius [12]).

Value Calculated by the Theory of Relativity by Considering the Allais Effect
The If we take into account the Allais disturbance and the residual arc observed during a total eclipse of the Sun, it will be necessary from the theory of relativity The angle does not correspond any more to the value calculated by the General theory of Relativity but rather to the average of the observations which gives a 10% deviation wider than the theoretical value (1.74'' + (1.74'' × 10%) = ~1.916'') [13]. In that case the equation would become Δα being a fragment of arc going from p towards the centre of the Sun, and which expresses a supplementary gravity due to the eclipse.
The formula of the General Relativity during total eclipse could thus be: The three ad hoc formulae (9) (10) (11), although in compliance with the observations, remain nevertheless profoundly deficient not to say erroneous.

Discussion
According to General Relativity, a light ray passing in the vicinity of a celestial body undergoes a deflection in the direction of the decreasing gravitational potential, that is turned towards the celestial body itself, deflection of size We suppose that the speed of light, given by equals 0, and that g 44 /2, who plays the gravitational potential role determining the movement of the material point in a gravitational field stipulated almost static, does not vary [14]. At ordinary times, without eclipse, the interferometric experiments practically validated this formula in which α and d are inversely proportional inside the point p ( Figure 2 & Figure 3). With a more stressed curvature of light, the deflection angle α becomes wider as much as d, the minimal distance of approach of the centre of the Sun, gets closer to the length of the solar radius. It is the inverse for a lesser curvature.
During a total eclipse, our reckoning from the gravitational disturbance pin down by the pendulum gives a distance d stretched out as well as a widened angle 2α. They are proportional, what seems incomprehensible. By locating 0.1634 arcsecond at p, the minimal distance of approach of the centre of the Sun d, slightly superior to the Sun radius R S , is surpassed. Point p placed at p', pushes Journal of Modern Physics Supposing that the pendulum got an excess of gravity, the calculation would have given a shorter distance d corresponding to a smaller angle 2α, that is going towards 1.6 arcseconds already observed during experiment of eclipse. Here also the distance d would be proportional to the angle 2α. It is clear that the size d observed during an eclipse is not the same as the theoretical value in normal time and is on average larger. We can suppose that the speed of light would not equal any more 0 (12) and that the gravitational potential can vary [15]. With the Allais effect of the 1954 eclipse, a ray of light passing along a celestial body would suffer a deflection on the side of the increasing gravitational potential, which is on the side opposed to the celestial body. The uv g would have varied in an unexpected way. There would have been, in addition to a concavity turned toward the Sun, which means that light rays curve with regard to the system of coordinates, a tiny concavity turned toward the outside, what indicates that starlight rays "straighten" [16]. It seems that from p pointing toward p' the curvature of the space around a big mass such the Sun decreases and that a particle (planet or photon) is solicited according to the Newtonian laws. As if the gravitational potential

Formula of GR Altered during Solar Eclipses with Antigravitational Potential
According to General Relativity, light emitted from a source far away from the  1 v c + could be considered as an antigravitational potential.

Eclipse and Radio Interferometry Measurements
We see that the numbers show that the Allais anomaly is in connection with the observed additional residual arcseconds and that both anomalies arise during a total solar eclipse.
Let us note on one hand that today the measure of these deflections is made by radio interferometry [1] [13] [16]. One of the advantages of this technique is that it can be made every year, by opposition to the measures of eclipse, which are sporadically taken and in inhospitable places.
The development of the interferometric methods in radio astronomy allowed verifying in a very precise way the predictions of Einstein and to impose strong limits on the possible anomalies of the General Relativity. On the other hand, it is strange that since 1919, while the best observations made by Eddington in favour of the value predicted by the General Relativity agreed in approximately 20% near, the measure of about four hundred stars during various eclipses did not allow to improve the precision of this method. The fact is that an exact agreement between theory and measurements has been obtained by radio interferometry but has never been obtained by eclipse technique [2]. The more effective measure with a precision of 0.05 of the bending of light made by radio interferometry inclines scientists to conclude that the General Relativity's value is confirmed, allows to release from eclipse experiences and end of story.
We conclude, on the contrary, that it rather confirms that there is an essential and intrinsic difference between the measures observed during eclipse and those  [18]. Our interpretation is that both anomalies result from the same phenomenon revealing an antigravity. The paraconical pendulum, of which the oscillation plane is free to turn all sides at the same time, seems to indicate that the more the anomaly increases the degree of oscillating plane (with regard to the plane corresponding to the Foucault effect), the more the deviated plane escapes the gravitation. The pendulum, and thus the Earth, is "lightened". Within the framework of the General Relativity, the excess of arcsecond would mean that there is "flatness", or a geodesic more remote from the Sun than the theoretical geodesic.

Two Manners to Experiment
Others could attribute it to an excess of gravity similar to the Pioneer effect [19].
Although the observational experiments are difficult it is important to compare experiments with total eclipse with other without eclipse for consistency. Fortunately, modern technology is available for such a comparison. The time delay can be measured as well as the arcseconds angles since the delay experienced by light passing a massive object is closely related to the deflection of starlight. Two manners thus offer to experiment to know if there is less or more gravity.

Measure the Angle of Deflection of Light
We could take the measure of light deflection near the Sun by using the radio interferometry on quasars. For some decades, the effect of deflection of the electromagnetic trajectories by a field of gravitation is determined by radio astro-

Measure Signal Delay
Currently the deflection of "light" is best measured using radio astronomy, since radio waves can be measured during the day without waiting for an eclipse of the Sun. Einstein predicts that light will be delayed instead of accelerated when

Possible Cosmological Consequences
We assume that there is a relation between the Allais effect and the not resolute anomaly of residual arc during total solar eclipse. It is evident at this stage that it needs further investigations in order to dissipate the confusion between significant gravitational anomaly and errors of observation, and determine if our calculation is indeed genuine or facility artefact. It must be taken into consideration that if the effects of these anomalies are real and in coincident evidence [22] [23], it gives a new aspect of the Allais effect which could lead at least to three possible cosmological consequences:

If the Allais Effect Is Real, Gravity Would Be Attractive and Repulsive
GR, based on the equivalence principle, is in an extension of special relativity and Newtonian gravity, but even if it is full of elegance and simplicity it doesn't mean that the theory is in agreement with recent observations (pioneer anomaly, anomaly of the astronomical unit, galaxy rotation curves, etc.) [24] [25]. If the Allais effect is real, gravitation could not be considered any more like a space-

The Allais Effect on Cosmological Scales Would Apply to the Gravitational Lenses and to the Distribution of Matter
It is easy to imagine that if the Allais effect is applied to the light-bending effect measured during a total eclipse of the Sun, then there is overwhelming evidence that this effect exists on various scales where eclipses are associated with light following curved paths through space distorted by the presence of matter.
According to GR, mass "warps" space-time to create gravitational fields and therefore bend light as a result. After this theory was confirmed in 1919 during a solar eclipse, Einstein realized that it was also possible for astronomical objects to bend light, and that under the correct conditions, one would observe multiple images of a single source, called a "gravitational lens" or sometimes a "gravita- Einstein's GR demonstrates that a large mass can deform spacetime and bend the path of light. So, a very massive object, such as a cluster of galaxies can act as a gravitational lens (deflector). When light passes through the cluster from an object lying behind it, the light is bent and focused to produce an image or images of the source. Viewed from the observer (the Earth), the image may be magnified, distorted, or multiplied by the lens, depending upon the position of the source with respect to the lensing mass. So, let us suppose that a sufficiently visible or invisible massive object is moving between Earth and the deflector, or between the deflector and the source, would not there be an Allais effect?
If the data could be compared, before, during and after, that the massive object travels between us, the gravitational lens and the source, there could be an excessive residual arc of the optic angle due to the antigravity, a divergent angle showing itself by a little less brilliance than foreseen by the Relativity, different images. The Einstein effect, in times of eclipse, should have a slightly lower shift of the spectral lines towards the red (blueshift) than in times without eclipse. In case it would be an effect similar to the Pioneer effect (over gravity) we should have a slightly superior movement of the spectral lines towards the red than in a frame without eclipse.
Because on the surface of celestial bodies reigns a field of very intense gravitation and the movements of the lines are considerable, gravitational lensing for R. Bagdoo the generalized Relativity is a powerful tool to estimate mass distribution on cosmological scales. But if the additional Allais effect is true, the mass distribution and the interpretation of gravity could be different.

Eclipse Perturbation Instead of Tidal Friction; Main Witness Becomes Main Culprit
Universal time and the length of day would be subject to variations not only because of the tides, atmospheric circulation, internal effects, but also because of Our suggestion is that the slowing rotation of the Earth, the increasing length of the day associated to the wider lunar orbit, are above all caused by eclipses instead of tidal friction. In this respect we suggest to examine in depth the Allais eclipse effect [32]. It could reveal that mechanisms of "antigravity" could produce "cosmological leaps" and "cosmological leap seconds" (different from "leap seconds" filling the split between the Earth's rotation second and the atomic clock second) and be so the main cause of the deceleration in the Earth's spin rate and, simultaneously, of the receding of the Moon. The listed total solar eclipses were always the only historic witnesses of the non-uniform change of rate of the rotation of Earth and of the day length. More than witness of the changes in Earth's dynamical behaviour, we think that eclipse could be also considered as perpetrator if the eclipse records and the Allais effect were scientifically investigated. Eclipse would have acted like a pyromaniac who, having lit a long series of fires, hurries to indicate every fire to the authorities who, in turn, use him as unique witness for the prosecution against possible suspects.

Conclusions
Does the relationship between the Allais effect and the higher displacement than predicted by GR of the positions of star images during solar eclipse a simple hypothesis, or is it a consequence of the observation at the time of the total eclipse?
We think that it is a consequence of the observational results at the time of the total eclipse and the measurements suggest that both anomalous phenomena have a common origin. Our approach to relating the two anomalies was first to calculate the gravitational acceleration in Paris during the disturbance caused by the total solar eclipse of June 30, 1954, starting from the plane of oscillation of the paraconical pendulum of M. Allais which rose 13.5 degrees. Then find the Earth's radius equivalent to this abnormal gravitational acceleration. Using the average horizontal parallax of the Sun which is 8.80'' of arc, we find that the abnormal addition to the Earth's radius during the eclipse is equivalent to a parallax angle that would vary by 0.1634''. By reversing the parallax, we find the same circumference for the Sun with an excess of arc. It just so happens that 0.1634'' corresponds to the deviation of about 10%, that is to say to the arc residue verified during total eclipse experiments and which is beyond the experimental errors.

R. Bagdoo Journal of Modern Physics
Scientific history seems to want to repeat itself. When the GR predicted for the deflection of starlight just grazing the edge of the Sun an angular distance of 1.74'', or two times the Newtonian prediction, the question of the precise value of the deviation became a matter of principle which had to allow choosing between both theories. The Relativity took it. Today, the Allais effect and the anomaly of residual arc during total solar eclipse persuade us that it is not the complete story. The observed 1.97'' for the deviation is higher than the number predicted by the calculation and in a proportion superior to the experimental errors.
And, as we tried to demonstrate, the unexplained arcseconds excess of these experiments would be in concomitance and accordance with the abrupt deviation of the plane of oscillation of the Allais pendulum with regard to the plane corresponding to the Foucault effect. GR does not explain the anomaly of the arc residue during total eclipses, which suggests that it is conceptually incomplete and that some substantive work needs to be done. We do not hesitate to assert that these confirmed experiences and these collected figures call into question the interpretation of GR and once again question our conception of the Universe.
