There is no such requirement to a mathematical model. The question is whether a mechanism can be identified to define what the speed of gravity is. Both Newtonian and GR fail at that. <shrug> > > Know what?

I would certain bet against that. <shrug> In the meantime, keep drinking more fermented diarrhea of Einstein the nitwit, the plagiarist, and the liar from Einstein Dingleberries. <shrug>

I am certain interested to see that math where these legions of astronomy students can conclude all bodies with the solar system or beyond can contribute exactly 530 arcseconds to the orbital advance of Mercurys perihelion.

What "whole equation" did Einstein base on observations of Mercury? I guess Mr. Kadoshima probably means the Schwarzschild metric which is one of the infinite numbers of solutions to the field equations that are static, spherically symmetric, asymptotically flat, and degenerative to Newtonian law of gravity. However, Einstein the nitwit, the plagiarist, and the liar had already predicted (3 G M / c^2 / R, where M = solar mass, R = average orbital distance to the sun) per revolution of advance in perihelion. That was about half a year before the field equations. In fact bragging about this so-called achievement was what prompted Hilbert to pull out that so-called Lagrangian as a density of some sort to the ever so mystic Einstein-Hilbert action. With that Lagrangian, Hilbert was about to derive the field equations. What Einstein the nitwit, the plagiarist, and the liar did was to mechanically copy Gerbers work. Both modified the Newtonian gravitational potential to do so. Gerbers approach was to design a speed dependent gravitational potential, while Einstein the nitwit, the plagiarist, and the liar chose to add a second order effect to the orbital distance. Of course, being a nitwit, Einstein the nitwit, the plagiarist, and the liar naturally made a lot of mistake on that. <shrug>

The GR equation of Einstein that this whole thread is all about: The advance of the perihelion of the orbits (i.e., exactly 43 arcsec/century in the case of Mercury) = 24pi^3(a^2/T^2c^2[1-e^2]) See page 163 of 'The Principle of Relativity' authored by Lorentz, Einstein, Minkowski, and Weyl, and originally published in German in 1923. This is in English in 'Gravity, the Glue of the Universe', therefore so are the definitions of the letters used in the equation. D.Y.K.

And it is your contention that Einstein derived General Relativity from this equation? So what were the other 162 pages of the book about do you think?

I posted that Einstein derived this GR equation from the 43 arcsec/centrury of Le Verrier's findings. Your logic is extremely weak, if you have any at all. Furthermore your responses to my posts positively demonstrates that your sense of cause and effect is non-existent. I hope you know that this equation does not work with the same degree of precession when applied to the other planets of the Solar System. Furthermore, the values of what T. Roberts claims as errorbars are astronomical when applied to many binary extra-Solar System bodies. So do not expect any more responses to your flummox posts. To argue with a fool only demonstrates that there are two. D.Y.K. |
