The Motion of the Perihelion of Mercury
THE MOTION OF THE PERIHELION OF MERCURY
In his general relativity calculation of the motion of the perihelion of Mercury Albert Einstein had only taken into account the gravitational actions between the Sun and the Mercury, which he also assumed as two points. What will be, according to the theory of general relativity, the value of the motion of the perihelion of Mercury if the gravitational actions of all the planets in the solar system are taken into account and also it is taken into account that the Sun is a little oblate? Have any done these calculations? Best regards Louis Nielsen Denmark

Different for each orbit as Venus, Earth and Jupiter advance. Have any done these calculations? Le Verrier, who had no computer.

Have any done these calculations? Best regards Louis Nielsen Denmark As fas as I know, the only person dealing explicitly and honestly with this is the French astrophysicist JeanMarc BonnetBidaud. Einstein has made his calculations on the assumption that the mass of the sun is perfectly spherical, and if it is not, the confirmation of relativity becomes in fact a refutation: http://astronomy.ifrance.com/pages/g.../einstein.html "Le deuxième test classique donne en revanche des inquiétudes. Historiquement, pourtant, l'explication de l'avance du périhélie de Mercure, proposé par Einstein luimême, donna ses lettres de noblesse à la relativité générale. Il s'agissait de comprendra pourquoi le périhélie de Mercure ( le point de son orbite le plus proche du soleil ) se déplaçait de 574 s d'arc par siècle. Certes, sur ces 574 s, 531 s'expliquaient par les perturbations gravitationnels dues aux autres planètes. Mais restait 43 s, le fameux effet "périhélique" inexpliqué par les lois de Newton. Le calcul relativiste d'Einstein donna 42,98 s ! L'accord et si parfait qu'il ne laisse la place à aucune discussion. Or depuis 1966, le soleil est soupçonné ne pas être rigoureusement sphérique mais légèrement aplati à l'équateur. Une très légère dissymétries qui suffirait à faire avancer le périhélie de quelques secondes d'arc. Du coup, la preuve se transformerait en réfutation puisque les 42,88 s du calcul d'Einstein ne pourrait pas expliquer le mouvement réel de Mercure."

I think we can dispense with the planets pretty quickly. Venus weighs 1/500,000 of Sun, and that's the nearest one. Effects from the Sun being oblate you would have to imagine are at least 2nd or 3rd order, and its not very oblate at all. Long and short is that measuring these effects would be experimentally impossible, I bet.

In an actual observation of Mercury’s orbital advance, there are 5,600” (in arcseconds) per century of observed perihelion advance. Among these, 5,025” are due to the 22,000year precession of earth’s orbital around the second. 532” were accounted for through inclusion of other planets. That leaves (5,600” – 5,015” = 43”) unaccounted for. I suspect this 5,600” per century of perihelion advance is not very accurate in the first place. I want to see error bars associated with this experiment. Tell me if that is too much to ask. What will be, according to the theory of general relativity, the value of the motion of the perihelion of Mercury if the gravitational actions of all the planets in the solar system are taken into account and also it is taken into account that the Sun is a little oblate? The 43” was calculated based on Paul Gerber’s work. Other mathematical methods do not yield the same result. shrug Have any done these calculations? There are at least 12 such calculations to predict Mercury’s orbital advance in which the spacetime with the Schwarzschild metric is just one of them according to Gerber’s method. shrug

Entirely correct. What will be, according to the theory of general relativity, the value of the motion of the perihelion of Mercury if the gravitational actions of all the planets in the solar system are taken into account and also it is taken into account that the Sun is a little oblate? Unknown to me, but I haven't done a literature search. The classical analysis for Mercury's perihelion precession is almost completely explained using perturbation theory, from the effects of other planets. There is no reason  except for it being hard  that the analysis can't be replicated while taking into account effects from the other planets. However, the effect between the Sun and Mercury is sufficient to explain what is observed. There's a breakdown in MTW, by the way. Have any done these calculations?

All Gerber did was guess the form of a velocitydependent potential that would give the same effects. The actual analysis was based on the works of Le Verrier. Do you have a literature reference for the assertion that other methods "do not yield the same result", or is this more of your typical nonsense that has no scholarly backing? [...]
