In 1954, physicist Maurice Allais discovered a gravitational anomaly when he used a Foucault pendulum during a solar eclipse. What it is about and how it is likely to happen On Monday, August 21, the total solar eclipse will finally occur, which has captured unparalleled attention in the United States for months. There will be thousands of photos, lots of comments, millions of interested people. There will also be a mass of spectators with special glasses and even half a kilo less in them. What remains to know is whether the Allais effect will occur.
In 1954, Maurice Allais, French economist and physicist, carried out a curious experiment. For this, he only had a pendulum of Foucault, who a century ago had demonstrated its gradual movement in unison with the rotation of the Earth. Everything on Earth moves in circular form every 24 hours, he stipulated, but in the vicinity of the equator it moves faster than at the poles.
Such a terrestrial movement causes the pendulum to barely move with each oscillation. The effect is known as precession and, although very small, it accumulates. However, Maurice Allais came to challenge him. He believed that gravity could arise as a consequence of a cosmic ether and that during an eclipse, precession – the effect accepted by physics – would be reversed. And he proved it. Did you prove it?
“The Allais effect is the supposed anomalous oscillation of a pendulum when a solar eclipse occurs,” Daniela Pérez, an astronomy doctor and postdoctoral researcher at CONICET of the Argentine Institute of Radio Astronomy (IAR), told Infobae.
Since 1954, the effect passed to posterity as the “Allais effect”. Its statement goes against the gravitational models. Since then, it has been the subject of questions, tests and counter-tests, ratifications and rectifications. “The first thing that should be asked is whether this effect really exists or is the product of insufficient experimental controls,” Perez said. “And if it exists, why it has been observed in some eclipses of Sun and in others not,” he continued.
The latest work published in this regard, said the astronomer, is 2010 and corresponds to the Argentine Horacio Salva. In “Searching the Allais effect during the total sun eclipse of July 11, 2010”, published in the journal Physical Review, the researcher analyzed the eclipse that could be seen in the country. In his results, he found no evidence of the Allais effect.
Is that according to traditional physics the rate of precession should not vary. It would have to be the same despite any eclipse. However, the effect did appear in previous studies. Allais himself replied in 1959 and noticed the anomaly. Another, in 1970, also detected a slight oscillation, although without clear causes.
So how can the Allais effect occur? “Those who think the effect is real, suggested several ‘explanations.'” The most radical is that the Allais effect is the product of a gravitational anomaly that can not be explained by the theory of general relativity. That return to the theory of ether, in which it is assumed, among other things, that the speed of light depends on the direction of movement.This is in contradiction with the first postulate of Special Relativity, “Perez replied.
Next Monday will unveil another mystery. Will the Allais effect be present? “I doubt if the effect really exists, and if I do not think it is due to some kind of gravitational anomaly,” he said. Although his scientific sustenance is weak, more than 50 years that contradicts to the own Albert Einstein.
