Eddington's 1919 hoax:

Frederick Soddy, An Address to the fourth Conference of Nobel Prizewinners at Lindau (Bodensee), S. Germany, 30.VI.1954: "Incidentally the attempt to verify this during a recent solar eclipse, provided the world with the most disgusting spectacle perhaps ever witnessed of the lengths to which a preconceived notion can bias what was supposed to be an impartial scientific inquiry. For Eddington, who was one of the party, and ought to have been excluded as an ardent supporter of the theory that was under examination, in his description spoke of the feeling of dismay which ran through the expedition when it appeared at one time that Einstein might be wrong! Remembering that in this particular astronomical investigation, the corrections for the normal errors of observation - due to diffraction, temperature changes, and the like - exceeded by many times the magnitude of the predicted deflection of the star's ray being looked for, one wonders exactly what this sort of "science" is really worth." http://www.reformation.edu/scripture-science-stott/aarch/pages/10-soddy-to-nobel-prizewinners.htm

In 1924 Eddington calculated the "Einstein shift" and commanded two observatories to confirm his estimate (by that time he was an all-powerful boss in post-truth physics). For half a century, the fraudulent test was deemed the most solid confirmation of Einstein's general relativity:

"Consider the case of astronomer Walter Adams. In 1925 he tested Einstein's theory of relativity by measuring the red shift of the binary companion of Sirius, brightest star in the sky. Einstein's theory predicted a red shift of six parts in a hundred thousand; Adams found just such an effect. A triumph for relativity. However, in 1971, with updated estimates of the mass and radius of Sirius, it was found that the predicted red shift should have been much larger – 28 parts in a hundred thousand. Later observations of the red shift did indeed measure this amount, showing that Adams' observations were flawed. He "saw" what he had expected to see." http://puritanreformed.blogspot.bg/2010/08/fallible-nature-of-supposed-objective.html

"In January 1924 Arthur Eddington wrote to Walter S. Adams at the Mt. Wilson Observatory suggesting a measurement of the "Einstein shift" in Sirius B and providing an estimate of its magnitude. Adams' 1925 published results agreed remarkably well with Eddington's estimate. Initially this achievement was hailed as the third empirical test of General Relativity (after Mercury's anomalous perihelion advance and the 1919 measurement of the deflection of starlight). It has been known for some time that both Eddington's estimate and Adams' measurement underestimated the true Sirius B gravitational redshift by a factor of four." http://adsabs.harvard.edu/abs/2010AAS...21530404H

"...Eddington asked Adams to attempt the measurement. [...] ...Adams reported an average differential redshift of nineteen kilometers per second, very nearly the predicted gravitational redshift. Eddington was delighted with the result... [...] In 1928 Joseph Moore at the Lick Observatory measured differences between the redshifts of Sirius and Sirius B... [...] ...the average was nineteen kilometers per second, precisely what Adams had reported. [...] More seriously damaging to the reputation of Adams and Moore is the measurement in the 1960s at Mount Wilson by Jesse Greenstein, J.Oke, and H.Shipman. They found a differential redshift for Sirius B of roughly eighty kilometers per second." http://adsabs.harvard.edu/full/1980QJRAS..21..246H

Jean-Marc Bonnet-Bidaud has a breathtaking hypothesis. According to him, initially Einsteinians were all fraudsters but the fraudulent period ended in 1971 when Eddington's second (Sirius B) major hoax was exposed. Then, in the 1970's, all Einsteinians became extremely honest:

"Le monde entier a cru pendant plus de cinquante ans à une théorie non vérifiée. Car, nous le savons aujourd'hui, les premières preuves, issues notamment d'une célèbre éclipse de 1919, n'en étaient pas. Elles reposaient en partie sur des manipulations peu avouables visant à obtenir un résultat connu à l'avance, et sur des mesures entachées d'incertitudes, quand il ne s'agissait pas de fraudes caractérisées. Il aura fallu attendre les années 1970 pour que de nouvelles méthodes parviennent enfin à fournir des preuves expérimentales solides de la relativité. [...] Autour de l'étoile brillante Sirius, on découvre une petite étoile, Sirius B, à la fois très chaude et très faiblement lumineuse. Pour expliquer ces deux particularités, il faut supposer que l'étoile est aussi massive que le Soleil et aussi petite qu'une planète comme la Terre. C'est Eddington lui-même qui aboutit à cette conclusion dont il voit vite l'intérêt : avec de telles caractéristiques, ces naines blanches sont extrêmement denses et leur gravité très puissante. Le décalage vers le rouge de la gravitation est donc 100 fois plus élevé que sur le Soleil. Une occasion inespérée pour mesurer enfin quelque chose d'appréciable. Eddington s'adresse aussitôt à Walter Adams, directeur de l'observatoire du mont Wilson, en Californie, afin que le télescope de 2,5 m de diamètre Hooker entreprenne les vérifications. Selon ses estimations, basées sur une température de 8 000 degrés de Sirius B, mesurée par Adams lui-même, le décalage vers le rouge prédit par la relativité, en s'élevant à 20 km/s, devrait être facilement mesurable. Adams mobilise d'urgence le grand télescope et expose 28 plaques photographiques pour réaliser la mesure. Son rapport, publié le 18 mai 1925, est très confus car il mesure des vitesses allant de 2 à 33 km/s. Mais, par le jeu de corrections arbitraires dont personne ne comprendra jamais la logique, le décalage passe finalement à 21 km/s, plus tard corrigé à 19 km/s, et Eddington de conclure : "Les résultats peuvent être considérés comme fournissant une preuve directe de la validité du troisième test de la théorie de la relativité générale." Adams et Eddington se congratulent, ils viennent encore de "prouver" Einstein. Ce résultat, pourtant faux, ne sera pas remis en cause avant 1971.. Manque de chance effectivement, la première mesure de température de Sirius B était largement inexacte : au lieu des 8 000 degrés envisagés par Eddington, l'étoile fait en réalité près de 30 000 degrés. Elle est donc beaucoup plus petite, sa gravité est plus intense et le décalage vers le rouge mesurable est de 89 km/s. C'est ce qu'aurait dû trouver Adams sur ses plaques s'il n'avait pas été "influencé" par le calcul erroné d'Eddington. L'écart est tellement flagrant que la suspicion de fraude a bien été envisagée." http://bonnetbidaud.free.fr/ce/relativite2008/pdf_CE/RELATIVITE-052-456.pdf

a high-level capitalist Eurocrat said on Tuesday, the Executive Vice-
President of the European Commission Frans Timmermans:

"Donbass recognition ‘one of the darkest day in Europe’s history’ – EU"

Nah, that was the carpet-bombing of Serbia, vermln!
