When applying GR to calculate Mercury's precession, the result is 43 arcseconds which coincides with the part of observed precession unexplained by newtonian theory . My question is: why the formula from GR gives precisely this unexpained 43 arcseconds and not the total observed precession of 5600 arcseconds per century as if the calculation had implicit the rest of approximations? I guess it is the way the GR derivation is set up but I'm curious abot how exactly.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks
